The International Plumbing Code, in this 2012 edition, is designed to meet these needs through model code regulations that safeguard the public health and safety in all communities, large and small. This comprehensive plumbing code establishes minimum regulations for plumbing systems using prescriptive and performance -related provisions. It is founded on broad -based principles that make possible the use of new materials and new plumbing designs. This 2012 edition is fully com- patible with all of the International Codes (I -Codes) published by the International Code Council (ICC), including the International Building Code, International Energy Conservation Code, Inter- national Existing Building Code, International Fire Code International Fuel Gas Code, Interna- tional Green Construction Code TM (to be available March 2012), International Mechanical Code, ICC Performance Code, International Private Sewage Disposal Code, International Property Mainte- nance Code, International Residential Code, International Swimming Pool and Spa Code TM (to be available March 2012), International Wildland-Urban Interface Code and International Zoning Code. The International Plumbing Code provisions provide many benefits, among which is the model code development process that offers an international forum for plumbing professionals to discuss performance and prescriptive code requirements. This forum provides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the application of provisions. The first edition of the International Plumbing Code (1995) was the culmination of an effort initiated in 1994 by a development committee appointed by the ICC and consisting of representatives of the three statutory members of the International Code Council at that time, including: Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). The intent was to draft a com- prehensive set of regulations for plumbing systems consistent with and inclusive of the scope of the existing model codes. Technical content of the latest model codes promulgated by BOCA, ICBO and SBCCI was utilized as the basis for the development. This 2012 edition presents the code as origi- nally issued, with changes as reflected in the subsequent editions through 2009 and with changes approved through the ICC Code Development Process through 2010. A new edition such as this is promulgated every three years. This code is founded on principles intended to establish provisions consistent with the scope of a plumbing code that adequately protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not restrict the use of new materials, products or methods of construction; and provisions that do not give preferential treatment to par- ticular types or classes of materials, products or methods of construction. The International Plumbing Code is available for adoption and use byjurisdictions internationally. Its use within a governmental jurisdiction is intended to be accomplished through adoption by refer- ence in accordance with proceedings establishing the jurisdiction's laws. At the time of adoption, jurisdictions should insert the appropriate information in provisions requiring specific local informa- tion, such as the name of the adopting jurisdiction. These locations are shown in bracketed words in small capital letters in the code and in the sample ordinance. The sample adoption ordinance on page xi addresses several key elements of a code adoption ordinance, including the information required for insertion into the code text. 2012 INTERNATIONAL PLUMBING CODe III I " ' CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAgemt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Maintenance The International Plumbing Code is kept up to date through the review of proposed changes submit- ted by code enforcing officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code development process in which all interested and affected parties may participate. The contents of this work are subject to change both through the Code Development Cycles and the governmental body that enacts the code into law. For more information regarding the code development process, contact the Codes and Standards Development Department of the Interna- tional Code Council. While the development procedure of the International Plumbing Code ensures the highest degree of care, ICC and ICC's members and those participating in the development of this code do not accept any liability resulting from compliance or noncompliance with the provisions, since ICC and its members do not have the power or authority to police or enforce compliance with the con- tents of this code. Only the governmental body that enacts the code into law has such authority. Code Development Committee Responsibilities (Letter Designations in Front of Section Numbers) In each code development cycle, proposed changes to the code are considered at the Code Devel- opment Hearings by the International Plumbing Code Development Committee, whose action con- stitutes a recommendation to the voting membership for final action on the proposed change. Proposed changes to a code section that has a number beginning with a letter in brackets are con- sidered by a different code development committee. For example, proposed changes to code sec- tions that have [B] in front of them (e.g. [B] 309.2) are considered by the appropriate International Building Code Development Committee (IBC -General) at the code development hearings. The content of sections in this code that begin with a letter designation is maintained by another code development committee in accordance with the following: [A] = Administrative Code Development Committee; [B] = International Building Code Development Committee (IBC —Fire Safety, General, Means of Egress or Structural); [E] = International Energy Conservation Code Development Committee; [F] = International Fire Code Development Committee; and [M] = International Mechanical Code Development Committee.

The groupings are as follows: Group A Codes (Heard in 2012, Code Change Proposals Deadline: January 3, 2012) Group B Codes (Heard in 2013, Code Change Proposals Deadline: January 3, 2013) International Building Code Administrative Provisions (Chapter 1 all codes except IRC, administrative updates to currently referenced standards, and designated definitions) International Fuel Gas Code International Energy Conservation Code International Mechanical Code International Existing Building Code International Plumbing Code International Fire Code International Private Sewage Disposal Code International Green Construction Code ICC Performance Code International Property Maintenance Code International Residential Code International Swimming Pool and Spa Code International Wildland-Urban Interface Code International Zoning Code Code change proposals submitted for code sections that have a letter designation in front of them will be heard by the respective committee responsible for such code sections. Because differ- ent committees will meet in different years, it is possible that some proposals for this code will be heard by a committee in a differentyear than the year in which the primary committee for this code meets. For example, every section of Chapter 1 of this code is designated as the responsibility of the Administrative Code Development Committee, and that committee is part of the Group B portion of the hearings. This committee will conduct its code development hearings in 2013 to consider all code change proposals for Chapter 1 of this code and proposals for Chapter 1 of all I -Codes except the International Residential Code and the ICC Performance Code. Therefore, any proposals received for Chapter 1 of this code will be deferred for consideration in 2013 by the Administrative Code Development Committee. Another example is Section 607.5 of this code which is designated as the responsibility of the International Energy Conservation Code Development Committee. This committee will conduct its code development hearings in 2013 to consider code change proposals in its purview, which includes any proposals to Section 607.5. In some cases, another committee in Group A will be responsible for a section of this code. For example, Section 314.2 has a [M] in front of the numbered section, indicating that this section of the code is the responsibility of the International Mechanical Code Development Committee. The International Mechanical Code is in Group A; therefore, any code change proposals to this section will be due before the Group A deadline of January 3, 2012, and these code change proposals will be assigned to the International Mechanical Code Development Committee for consideration. It is very important that anyone submitting code change proposals understand which code devel- opment committee is responsible for the section of the code that is the subject of the code change proposal.

The regulations for plumbing systems in one- and two-family dwellings and townhouses are covered by Chapters 25 through 33 of the International Residential Code (IRC). The IPC addresses general plumbing regulations, fixture requirements, water heater installations and systems for water distribution, sanitary drainage, special wastes, venting, storm drainage and medical gases. The IPC does not address fuel gas piping systems as those systems are covered by the International Fuel Gas Code (IFGC). The IPC also does not regulate swimming pool piping systems, process piping systems, or utility -owned piping and systems. The purpose of the IPC is to the establish the mini- mum acceptable level of safety to protect life and property from the potential dangers associated with supplying potable water to plumbing fixtures and outlets and the conveyance of bacteria -laden waste water from fixtures. The IPC is primarily a specification -oriented (prescriptive) code with some performance -oriented text. For example, Section 405.1 is a performance statement but Chapter 6 contains the prescriptive requirements that will cause Section 405.1 to be satisfied. Where a building contains plumbing fixtures, those fixtures requiring water must be provided with an adequate supply of water for proper operation. The number of required plumbing fixtures for a building is specified by this code and is based upon the anticipated maximum number of occu- pants for the building and the type of building occupancy. This code provides prescriptive criteria for sizing piping systems connected to those fixtures. Through the use of code -approved materials and the installation requirements specified in this code, plumbing systems will perform their intended function over the life of the building. In summary, the IPC sets forth the minimum require- ments for providing safe water to a building as well as a safe manner in which liquid -borne wastes are carried away from a building. Arrangement and Format of the 2012 IPC The format of the IPC allows each chapter to be devoted to a particular subject with the exception of Chapter 3 which contains general subject matters that are not extensive enough to warrant their own independent chapter. The IPC is divided into thirteen different parts: Chapters Subjects 1-2 Administration and Definitions 3 General Regulations 4 Fixtures, Faucets and Fixture Fittings 5 Water Heaters 6 Water Supply and Distribution 7 Sanitary Drainage 8 Indirect/Special Wastes 9 Vents 10 Traps, Interceptors and Separators 11 Storm Drainage 12 Special Piping (Medical Gas) 13 Gray Water Recycling Systems 14 Referenced Standards Appendices A-G Appendices 2012 INTERNATIONAL PLUMBING CODE® vii I " ' CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAgemt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER The following is a chapter -by -chapter synopsis of the scope and intent of the provisions of the International Plumbing Code: Chapter 1 Scope and Administration. This chapter contains provisions for the application, enforcement and administration of subsequent requirements of the code. In addition to establish- ing the scope of the code, Chapter 1 identifies which buildings and structures come under its pur- view. Chapter 1 is largely concerned with maintaining "due process of law" in enforcing the requirements contained in the body of this code. Only through careful observation of the adminis- trative provisions can the building official reasonably expect to demonstrate that "equal protection under the law" has been provided. Chapter 2 Definitions. Chapter 2 is the repository of the definitions of terms used in the body of the code. Codes are technical documents and every word, term and punctuation mark can impact the meaning of the code text and the intended results. The code often uses terms that have a unique meaning in the code and the code meaning can differ substantially from the ordinarily understood meaning of the term as used outside of the code. The terms defined in Chapter 2 are deemed to be of prime importance in establishing the mean- ing and intent of the code text that uses the terms. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined. Where understanding of a term's definition is especially key to or necessary for understanding of a particular code provision, the term is shown in italics wherever it appears in the code. This is true only for those terms that have a meaning that is unique to the code. In other words, the generally understood meaning of a term or phrase might not be sufficient or consistent with the meaning pre- scribed by the code; therefore, it is essential that the code -defined meaning be known. Guidance regarding tense, gender and plurality of defined terms as well as guidance regarding terms not defined in this code is provided. Chapter 3 General Regulations. The content of Chapter 3 is often referred to as "miscella- neous," rather than general regulations. This is the only chapter in the code whose requirements do not interrelate. If a requirement cannot be located in another chapter, it should be located in this chapter. Chapter 3 contains safety requirements for the installation of plumbing and nonplumbing requirements for all types of fixtures. This chapter also has requirements for the identification of pipe, pipe fittings, traps, fixtures, materials and devices used in plumbing systems. The safety requirements of this chapter provide protection for the building's structural mem- bers, as well as prevent undue stress and strain on pipes. The building's structural stability is pro- tected by the regulations for cutting and notching of structural members. Additional protection for the building occupants includes requirements to maintain the plumbing in a safe and sanitary condi- tion, as well as privacy for those occupants. Chapter 4 Fixtures, Faucets and Fixture Fittings. This chapter regulates the minimum num- ber of plumbing fixtures that must be provided for every type of building. This chapter also regu- lates the quality of fixtures and faucets by requiring those items to comply with nationally recognized standards. Because fixtures must be properly installed so that they are usable by the occupants of the building, this chapter contains the requirements for the installation of fixtures. Because the requirements for the number of plumbing fixtures affects the design of a building, Chapter 29 of the International Building Code (IBC) includes, verbatim, many of the requirements listed in Chapter 4 of this code. Chapter 5 Water Heaters. Chapter 5 regulates the design, approval and installation of water heaters and related safety devices. The intent is to minimize the hazards associated with the instal- lation and operation of water heaters. Although this code does not regulate the size of a water heater, it does regulate all other aspects of the water heater installation such as temperature and pressure relief valves, safety drip pans, installation and connections. Where a water heater also sup- plies water for space heating, this chapter regulates the maximum water temperature supplied to the water distribution system. viii 2012 INTERNATIONAL PLUMBING CODE® i l i Copy,ghtOo O N I ICC ALL RIGHTS RESERVED Awsed by ().(-)O,d,,Nombsx 100760189 oc Sep 9o.2o19 m. oo PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, iff S I ( N ,Fod,Yo,,bymytl,dputy,o,Abau�to,o,sd Single —oPIA PTymg anodmgp� dortuokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,ED REAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 6 Water Supply and Distribution. This chapter regulates the supply of potable water from both public and individual sources to every fixture and outlet so that it remains potable and uncontaminated. Chapter 6 also regulates the design of the water distribution system, which will allow fixtures to function properly and also help prevent backflow conditions. The unique require- ments of the water supply for health care facilities are addressed separately. It is critical that the potable water supply system remain free of actual or potential sanitary hazards by providing protec- tion against backflow. Chapter 7 Sanitary Drainage. The purpose of Chapter 7 is to regulate the materials, design and installation of sanitary drainage piping systems as well as the connections made to the system. The intent is to design and install sanitary drainage systems that will function reliably, that are neither undersized nor oversized and that are constructed from materials, fittings and connections as pre- scribed herein. This chapter addresses the proper use of fittings for directing the flow into and within the sanitary drain piping system. Materials and provisions necessary for servicing the drain- age system are also included in this chapter. Chapter 8 Indirect/Special Waste. This chapter regulates drainage installations that require an indirect connection to the sanitary drainage system. Fixtures and plumbing appliances, such as those associated with food preparation or handling, health care facilities and potable liquids, must be protected from contamination that can result from connection to the drainage system. An indi- rect connection prevents sewage from backing up into a fixture or appliance, thus providing protec- tion against potential health hazards. The chapter also regulates special wastes containing hazardous chemicals. Special waste must be treated to prevent any damage to the sanitary drainage piping and to protect the sewage treatment processes. Chapter 9 Vents. Chapter 9 covers the requirements for vents and venting. Knowing why venting is required makes it easier to understand the intent of this chapter. Venting protects every trap against the loss of its seal. Provisions set forth in this chapter are geared toward limiting the pres- sure differentials in the drainage system to a maximum of 1 inch of water column (249 Pa) above or below atmospheric pressure (i.e., positive or negative pressures). Chapter 10 Traps, Interceptors and Separators. This chapter contains design requirements and installation limitations for traps. Prohibited types of traps are specifically identified. Where fix- tures do not frequently replenish the water in traps, a method is provided to ensure that the water seal of the trap will be maintained. Requirements for the design and location of various types of interceptors and separators are provided. Specific venting requirements are given for separators and interceptors as those requirements are not addressed in Chapter 9. Chapter 11 Storm Drainage. Chapter 11 regulates the removal of storm water typically associ- ated with rainfall. The proper installation of a storm drainage system reduces the possibility of structural collapse of a flat roof, prevents the leakage of water through the roof, prevents damage to the footings and foundation of the building and prevents flooding of the lower levels of the build- ing. Chapter12 Special Piping and Storage Systems. This chapter contains the requirements for the design, installation, storage, handling and use of nonflammable medical gas systems, including inhalation anesthetic and vacuum piping systems, bulk oxygen storage systems and oxygen -fuel gas systems used for welding and cutting operations. The intent of these requirements is to minimize the potential fire and explosion hazards associated with the gases used in these systems. Chapter13 Gray Water Recycling Systems. This chapter regulates the design and installation of gray water collection and disposal systems. The reduction of the use of potable water in buildings has led to the use of gray water for flushing of water closets and urinals and subsurface irrigation. As such, this chapter provides the overall requirements for these systems. 2012 INTERNATIONAL PLUMBING CODE® ix I i l i Copy,ghtOO?.ot I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m. oo PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —ooly mpymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter 14 Referenced Standards. The code contains numerous references to standards that are used to regulate materials and methods of construction. Chapter 14 contains a comprehensive list of all standards that are referenced in the code. The standards are part of the code to the extent of the reference to the standard. Compliance with the referenced standard is necessary for compli- ance with this code. By providing specifically adopted standards, the construction and installation requirements necessary for compliance with the code can be readily determined. The basis for code compliance is, therefore, established and available on an equal basis to the code official, contractor, designer and owner. Chapter 14 is organized in a manner that makes it easy to locate specific standards. It lists all of the referenced standards, alphabetically, by acronym of the promulgating agency of the standard. Each agency's standards are then listed in either alphabetical or numeric order based upon the stan- dard identification. The list also contains the title of the standard; the edition (date) of the standard referenced; any addenda included as part of the ICC adoption; and the section or sections of this code that reference the standard. Appendix A Plumbing Permit Fee Schedule. Appendix A provides a format for a fee schedule. Appendix B Rates of Rainfall for Various Cities. Appendix B provides specific rainfall rates for major cities in the United States. Appendix C Vacuum Drainage System. Appendix C offers basic information on how a vacuum drainage system relates to the code, should a vacuum drainage system be used for a building. Appendix D Degree Day and Design Temperatures. This appendix provides valuable tem- perature information for designers and installers of plumbing systems in areas where freezing tem- peratures might exist. Appendix E Sizing of Water Piping System. Appendix E provides two recognized methods for sizing the water service and water distribution piping for any structure. The method under Section E103 provides friction loss diagrams which require the user to "plot" points and read values from the diagrams in order to perform the required calculations and necessary checks. This method is the most accurate of the two presented in this appendix. The method under Section E201 is known to be conservative; however, very few calculations are necessary in order to determine a pipe size that satisfies the flow requirements of any application. Appendix F Structural Safety. Appendix F is provided so that the user does not have to refer to another code book for limitations for cutting, notching and boring of sawn lumber and cold -formed steel framing. 2012 INTERNATIONAL PLUMBING CODE® Copy,gbt OO?.ot I ICC ALL RIGHTS RESERVED Awsed by ().

At least three percolation tests in each system area shall be conducted. The holes shall be spaced uniformly in relation to the bottom depth of the proposed absorption system. More percolation tests shall be made where necessary, depending on system design. 1303.7.1.1 Percolation test hole. The test hole shall be dug or bored. The test hole shall have vertical sides and a horizontal dimension of 4 inches to 8 inches (102 mm to 203 mind. The bottom and sides of the hole shall be scratched with a sharp -pointed instrument to expose the natural soil. All loose material shall be removed from the hole and the bottom shall be covered with 2 inches (51 mm) of gravel or coarse sand. 1303.7.1.2 Test procedure, sandy soils. The hole shall be filled with clear water to a minimum of 12 inches (305 mm) above the bottom of the hole for tests in sandy soils. The time for this amount of water to seep away shall be determined, and this procedure shall be repeated if the water from the second filling of the hole seeps away in 10 minutes or less. The test shall proceed as follows: Water shall be added to a point not more than 6 inches (152 mm) above the gravel or coarse sand. Thereupon, from a fixed reference point, water levels shall be measured at 10-minute intervals for a period of 1 hour. Where 6 inches (152 mm) of water seeps away in less than 10 minutes, a shorter interval between measure- ments shall be used, but in no case shall the water depth exceed 6 inches (152 mind. Where 6 inches (152 mm) of water seeps away in less than 2 minutes, the test shall be stopped and a rate of less than 3 minutes per inch (7.2 s/ mm) shall be reported. The final water level drop shall be used to calculate the percolation rate. Soils not meeting the above requirements shall be tested in accordance with Section 1303.7.1.3. 1303.7.1.3 Test procedure, other soils. The hole shall be filled with clear water, and a minimum water depth of 12 inches (305 mm) shall be maintained above the bot- tom of the hole for a 4-hour period by refilling whenever necessary or by use of an automatic siphon. Water remaining in the hole after 4 hours shall not be removed. Thereafter, the soil shall be allowed to swell not less than 16 hours or more than 30 hours. Immediately after the soil swelling period, the measurements for determin- ing the percolation rate shall be made as follows: any soil sloughed into the hole shall be removed and the water level shall be adjusted to 6 inches (152 mm) above the gravel or coarse sand. Thereupon, from a fixed reference point, the water level shall be measured at 30-minute intervals for a period of 4 hours, unless two successive water level drops do not vary by more than '/,s inch (1.59 min). At least three water level drops shall be observed and recorded. The hole shall be filled with clear water to a point not more than 6 inches (152 mm) above the gravel or coarse sand whenever it becomes nearly empty. Adjustments of the water level shall not be made during the three measurement periods except to the limits of the last measured water level drop. When the first 6 inches (152 mm) of water seeps away in less than 30 minutes, the time interval between measurements shall be 10 min- utes and the test run for 1 hour. The water depth shall not exceed 5 inches (127 mm) at any time during the measure- ment period. The drop that occurs during the final mea- surement period shall be used in calculating the percolation rate. 1303.7.1.4 Mechanical test equipment Mechanical per- colation test equipment shall be of an approved type. 1303.7.2 Permeability evaluation. Soil shall be evaluated for estimated percolation based on structure and texture in accordance with accepted soil evaluation practices. Borings shall be made in accordance with Section 1303.7.1 for eval- uating the soil. 1303.8 Subsurface landscape irrigation site location. The sur- face grade of all soil absorption systems shall be located at a point lower than the surface grade of any water well or reservoir on the same or adjoining lot. Where this is not possible, the site shall be located so surface water drainage from the site is not directed toward a well or reservoir. The soil absorption system shall be located with a minimum horizontal distance between various elements as indicated in Table 1303.8. Private sewage disposal systems in compacted areas, such as parking lots and driveways, are prohibited. Surface water shall be diverted away from any soil absorption site on the same or neighboring lots. 2012 INTERNATIONAL PLUMBING CODE" 101 I II I CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAgemt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER GRAY WATER RECYCLING SYSTEMS TABLE 1303.8 LOCATION OF GRAY WATER SYSTEM ELEMENT MINIMUM HORIZONTAL DISTANCE HOLDINGTANK (feet) IRRIGATION DISPOSAL FIELD (feet) Buildings 5 2 Lot line adjoining private property 5 5 Water wells 50 100 Streams and lakes 50 50 Seepage pits 5 5 Septic tanks 0 5 Water service 5 5 Public water main 10 10 For SI 1 foot - 304 8 min 1303.9 Installation.

REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,EDORD, COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E SIZING OF WATER PIPING SYSTEM The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance. SECTION E101 GENERAL E101.1 Scope E101.1.1 This appendix outlines two procedures for sizing a water piping system (see Sections E103.3 and E201.1). The design procedures are based on the minimum static pressure available from the supply source, the head changes in the system caused by friction and elevation, and the rates of flow necessary for operation of various fixtures. E101.1.2 Because of the variable conditions encountered in hydraulic design, it is impractical to specify definite and detailed rules for sizing of the water piping system. Accordingly, other sizing or design methods conforming to good engineering practice standards are acceptable alternatives to those presented herein. SECTION E102 INFORMATION REQUIRED E102.1 Preliminary. Obtain the necessary information regarding the minimum daily static service pressure in the area where the building is to be located. If the building supply is to be metered, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes likely to be used. Friction loss data can be obtained from most manufacturers of water meters. E102.2 Demand load. E102.2.1 Estimate the supply demand of the building main and the principal branches and risers of the system by totaling the corresponding demand from the applicable part of Table E103.3(3). E102.2.2 Estimate continuous supply demands in gallons per minute (L/m) for lawn sprinklers, air conditioners, etc., and add the sum to the total demand for fixtures. The result is the estimated supply demand for the building sup- ply. SECTION E103 SELECTION OF PIPE SIZE E103.1 General. Decide from Table 604.3 what is the desir- able minimum residual pressure that should be maintained at the highest fixture in the supply system. If the highest group of fixtures contains flushometer valves, the pressure for the group should be not less than 15 pounds per square inch (psi) (103.4 kPa) flowing. For flush tank supplies, the available pressure should be not less than 8 psi (55.2 kPa) flowing, except blowout action fixtures must be not less than 25 psi (172.4 kPa) flowing. E103.2 Pipe sizing. E103.2.1 Pipe sizes can be selected according to the fol- lowing procedure or by other design methods conforming to acceptable engineering practice and approved by the administrative authority. The sizes selected must not be less than the minimum required by this code. E103.2.2 Water pipe sizing procedures are based on a sys- tem of pressure requirements and losses, the sum of which must not exceed the minimum pressure available at the supply source. These pressures are as follows: 1. Pressure required at fixture to produce required flow. See Sections 604.3 and 604.5. 2. Static pressure loss or gain (due to head) is com- puted at 0.433 psi per foot (9.8 kPa/m) of elevation change. Example: Assume that the highest fixture supply outlet is 20 feet (6096 mm) above or below the supply source. This produces a static pressure differential of 20 feet by 0.433 psi/foot (2096 mm by 9.8 kPa/m) and an 8.66 psi (59.8 kPa) loss. 3. Loss through water meter. The friction or pressure loss can be obtained from meter manufacturers. 4. Loss through taps in water main. 5. Losses through special devices such as filters, soft- eners, backflow prevention devices and pressure regulators. These values must be obtained from the manufacturers. 6. Loss through valves and fittings. Losses for these items are calculated by converting to equivalent length of piping and adding to the total pipe length. 7. Loss due to pipe friction can be calculated when the pipe size, the pipe length and the flow through the pipe are known. With these three items, the friction loss can be determined. For piping flow charts not included, use manufacturers' tables and velocity rec- ommendations. Note: For the purposes of all examples, the follow- ing metric conversions are applicable: 1 cubic foot per minute = 0.4719 L/s 1 square foot = 0.0929 m' 1 degree = 0.0175 rad 1 pound per square inch = 6.895 kPa 1 inch = 25.4 mm 2012 INTERNATIONAL PLUMBING CODE" 125 I II I C,gbtOO?.ot I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAg—mt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,iNb,to,au o,sd Single —ooly, mpymg Pod-Pyo,k,Fokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E 1 foot = 304.8 mm 1 gallon per minute = 3.785 L/m E103.3 Segmented loss method. The size of water service mains, branch mains and risers by the segmented loss method, must be determined according to water supply demand [gpm (L/m)], available water pressure [psi (kPa)] and friction loss caused by the water meter and developed length of pipe [feet (m)], including equivalent length of fittings. This design procedure is based on the following parameters: • Calculates the friction loss through each length of the pipe. • Based on a system of pressure losses, the sum of which must not exceed the minimum pressure available at the street main or other source of supply. • Pipe sizing based on estimated peak demand, total pressure losses caused by difference in elevation, equipment, developed length and pressure required at most remote fixture, loss through taps in water main, losses through fittings, filters, backflow prevention devices, valves and pipe friction. Because of the variable conditions encountered in hydraulic design, it is impractical to specify definite and detailed rules for sizing of the water piping system. Current sizing methods do not address the differences in the probability of use and flow characteristics of fixtures between types of occupancies. Creating an exact model of predicting the demand for a build- ing is impossible and final studies assessing the impact of water conservation on demand are not yet complete. The fol- lowing steps are necessary for the segmented loss method. 1. Preliminary. Obtain the necessary information regard- ing the minimum daily static service pressure in the area where the building is to be located. If the building supply is to be metered, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes to be used. Friction loss data can be obtained from manufacturers of water meters. It is essential that enough pressure be available to overcome all system losses caused by friction and elevation so that plumbing fixtures operate properly. Section 604.6 requires the water distribution system to be designed for the minimum pressure available taking into consid- eration pressure fluctuations. The lowest pressure must be selected to guarantee a continuous, adequate supply of water. The lowest pressure in the public main usu- ally occurs in the summer because of lawn sprinkling and supplying water for air-conditioning cooling tow- ers. Future demands placed on the public main as a result of large growth or expansion should also be con- sidered. The available pressure will decrease as addi- tional loads are placed on the public system. 2. Demand load. Estimate the supply demand of the building main and the principal branches and risers of the system by totaling the corresponding demand from the applicable part of Table E103.3(3). When estimat- ing peak demand sizing methods typically use water supply fixture units (w.s.f.u.) [see Table E103.3(2)]. This numerical factor measures the load -producing effect of a single plumbing fixture of a given kind. The use of such fixture units can be applied to a single basic probability curve (or table), found in the various sizing methods [Table E103.3(3)]. The fixture units are then converted into gallons per minute (L/m) flow rate for estimating demand. 2.1. Estimate continuous supply demand in gallons per minute (L/m) for lawn sprinklers, air condi- tioners, etc., and add the sum to the total demand for fixtures. The result is the estimated supply demand for the building supply. Fixture units cannot be applied to constant use fixtures such as hose bibbs, lawn sprinklers and air con- ditioners. These types of fixtures must be assigned the gallon per minute (L/m) value. 3. Selection of pipe size. This water pipe sizing procedure is based on a system of pressure requirements and losses, the sum of which must not exceed the minimum pressure available at the supply source. These pressures are as follows: 3.1. Pressure required at the fixture to produce required flow. See Section 604.3 and Section 604.5. 3.2. Static pressure loss or gain (because of head) is computed at 0.433 psi per foot (9.8 kPa/m) of elevation change. 3.3. Loss through a water meter. The friction or pressure loss can be obtained from the manu- facturer. 3.4. Loss through taps in water main [see Table E103.3(4)]. 3.5. Losses through special devices such as filters, softeners, backflow prevention devices and pressure regulators. These values must be obtained from the manufacturers. 3.6. Loss through valves and fittings [see Tables E103.3(5) and E103.3(6)]. Losses for these items are calculated by converting to equivalent length of piping and adding to the total pipe length. 3.7. Loss caused by pipe friction can be calculated when the pipe size, the pipe length and the flow through the pipe are known. With these three items, the friction loss can be determined using Figures E103.3(2) through E103.3(7). When using charts, use pipe inside diameters. For pip- ing flow charts not included, use manufactur- ers' tables and velocity recommendations. Before attempting to size any water supply sys- tem, it is necessary to gather preliminary infor- mation which includes available pressure, piping material, select design velocity, eleva- tion differences and developed length to most remote fixture. The water supply system is divided into sections at major changes in eleva- tion or where branches lead to fixture groups. The peak demand must be determined in each part of the hot and cold water supply system 126 2012 INTERNATIONAL PLUMBING CODE" Co,gbt@ ON I ICC ALL RIGHTS RESERVED A-P—d by ().(-)O,d,,Nombsx 1007601e9 oc SIP SO,2o19 oa. oo PM(PDT)p—Potto IL eAg—mt,oUICC No FYUP ep,odw.noa oAYUP, S I ( ,Fod,Yo,,bymytl,dputy,o,ANb�to,au o�sd Single—mlym,ymg and-Pyo,k,Fokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE PEDREAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E which includes the corresponding water supply fixture unit and conversion to gallons per min- ute (L/m) flow rate to be expected through each section. Sizing methods require the determina- tion of the "most hydraulically remote" fixture to compute the pressure loss caused by pipe and fittings. The hydraulically remote fixture repre- sents the most downstream fixture along the circuit of piping requiring the most available pressure to operate properly. Consideration must be given to all pressure demands and losses, such as friction caused by pipe, fittings and equipment, elevation and the residual pres- sure required by Table 604.3. The two most common and frequent complaints about the water supply system operation are lack of ade- quate pressure and noise. Problem: What size Type L copper water pipe, service and distribution will be required to serve a two-story factory building having on each floor, back-to-back, two toilet rooms each equipped with hot and cold water? The highest fixture is 21 feet (6401 mm) above the street main, which is tapped with a 2-inch (51 mm) corporation cock at which point the minimum pressure is 55 psi (379.2 kPa). In the building base- ment, a 2-inch (51 mm) meter with a maximum pressure drop of 11 psi (75.8 kPa) and 3-inch (76 mm) reduced pressure principle backflow preventer with a maximum pressure drop of 9 psi (621 kPa) are to be installed. The system is shown by Figure E103.3(1). To be determined are the pipe sizes for the service main and the cold and hot water distribution pipes. Solution: A tabular arrangement such as shown in Table E103.3(1) should first be constructed. The steps to be fol- lowed are indicated by the tabular arrangement itself as they are in sequence, columns 1 through 10 and lines A through L. Step 1 Columns 1 and 2: Divide the system into sections break- ing at major changes in elevation or where branches lead to fixture groups. After point B [see Figure E103.3(1)], separate consideration will be given to the hot and cold water piping. Enter the sections to be considered in the service and cold water piping in Column 1 of the tabular arrangement. Column 1 of Table E103.3(1) provides a line -by-line recommended tabular arrangement for use in solving pipe sizing. The objective in designing the water supply system is to ensure an adequate water supply and pressure to all fix- tures and equipment. Column 2 provides the pounds per square inch (psi) to be considered separately from the min- imum pressure available at the main. Losses to take into consideration are the following: the differences in eleva- tions between the water supply source and the highest water supply outlet, meter pressure losses, the tap in main loss, special fixture devices such as water softeners and backflow prevention devices and the pressure required at the most remote fixture outlet. The difference in elevation can result in an increase or decrease in available pressure at the main. Where the water supply outlet is located above the source, this results in a loss in the available pres- sure and is subtracted from the pressure at the water source. Where the highest water supply outlet is located below the water supply source, there will be an increase in pressure that is added to the available pressure of the water source. Column 3: According to Table E103.3(3), determine the gpm (L/m) of flow to be expected in each section of the system. These flows range from 28.6 to 108 gpm. Load values for fixtures must be determined as water supply fix- ture units and then converted to a gallon -per -minute (gpm) rating to determine peak demand. When calculating peak demands, the water supply fixture units are added and then converted to the gallon -per -minute rating. For continuous flow fixtures such as hose bibbs and lawn sprinkler sys- tems, add the gallon -per -minute demand to the intermit- tent demand of fixtures. For example, a total of 120 water supply fixture units is converted to a demand of 48 gallons per minute. Two hose bibbs x 5 gpm demand = 10 gpm. Total gpm rating = 48.0 gpm + 10 gpm = 58.0 gpm demand. Step 2 Line A: Enter the minimum pressure available at the main source of supply in Column 2. This is 55 psi (379.2 kPa). The local water authorities generally keep records of pres- sures at different times of day and year. The available pressure can also be checked from nearby buildings or from fire department hydrant checks. Line B: Determine from Table 604.3 the highest pressure required for the fixtures on the system, which is 15 psi (103.4 kPa), to operate a flushometer valve. The most remote fixture outlet is necessary to compute the pressure loss caused by pipe and fittings, and represents the most downstream fixture along the circuit of piping requiring the available pressure to operate properly as indicated by Table 604.3. Line C: Determine the pressure loss for the meter size given or assumed. The total water flow from the main through the service as determined in Step 1 will serve to aid in the meter selected. There are three common types of water meters; the pressure losses are determined by the American Water Works Association Standards for dis- placement type, compound type and turbine type. The maximum pressure loss of such devices takes into consid- eration the meter size, safe operating capacity (gpm) and maximum rates for continuous operations (gpm). Typi- cally, equipment imparts greater pressure losses than pip- ing. Line D: Select from Table E103.3(4) and enter the pres- sure loss for the tap size given or assumed. The loss of pressure through taps and tees in pounds per square inch (psi) are based on the total gallon -per -minute flow rate and size of the tap. Line E: Determine the difference in elevation between the main and source of supply and the highest fixture on the system. Multiply this figure, expressed in feet, by 0.43 psi (2.9 kPa). Enter the resulting psi loss on Line E. The dif- ference in elevation between the water supply source and the highest water supply outlet has a significant impact on 2012 INTERNATIONAL PLUMBING CODE" 127 I II I Co,gbtOO?.ot I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAg—mt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —ooly, mpymg Pod-Pyo,k,Fokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E the sizing of the water supply system. The difference in elevation usually results in a loss in the available pressure because the water supply outlet is generally located above the water supply source. The loss is caused by the pressure required to lift the water to the outlet. The pressure loss is subtracted from the pressure at the water source. Where the highest water supply outlet is located below the water source, there will be an increase in pressure which is added to the available pressure of the water source. Lines F, G and H: The pressure losses through filters, backflow prevention devices or other special fixtures must be obtained from the manufacturer or estimated and entered on these lines. Equipment such as backflow pre- vention devices, check valves, water softeners, instanta- neous or tankless water heaters, filters and strainers can impart a much greater pressure loss than the piping. The pressure losses can range from 8 psi to 30 psi. Step 3 Line I: The sum of the pressure requirements and losses that affect the overall system (Lines B through H) is entered on this line. Summarizing the steps, all of the sys- tem losses are subtracted from the minimum water pres- sure. The remainder is the pressure available for friction, defined as the energy available to push the water through the pipes to each fixture. This force can be used as an aver- age pressure loss, as long as the pressure available for fric- tion is not exceeded. Saving a certain amount for available water supply pressures as an area incurs growth, or because of aging of the pipe or equipment added to the system is recommended. Step 4 Line J: Subtract Line I from Line A. This gives the pres- sure that remains available from overcoming friction losses in the system. This figure is a guide to the pipe size that is chosen for each section, incorporating the total fric- tion losses to the most remote outlet (measured length is called developed length). Exception: When the main is above the highest fixture, the resulting psi must be considered a pressure gain (static head gain) and omitted from the sums of Lines B through H and added to Line J. The maximum friction head loss that can be tolerated in the system during peak demand is the difference between the static pressure at the highest and most remote outlet at no -flow conditions and the minimum flow pressure required at that outlet. If the losses are within the required limits, then every run of pipe will also be within the required friction head loss. Static pressure loss is the most remote outlet in feet x 0.433 = loss in psi caused by eleva- tion differences. Step 5 Column 4: Enter the length of each section from the main to the most remote outlet (at Point E). Divide the water supply system into sections breaking at major changes in elevation or where branches lead to fixture groups. Step 6 E103.3.3. Selection of pipe size, Step 6 Column 5: When selecting a trial pipe size, the length from the water service or meter to the most remote fixture outlet must be mea- sured to determine the developed length. However, in sys- tems having a flushometer valve or temperature controlled shower at the top most floors the developed length would be from the water meter to the most remote flushometer valve on the system. A rule of thumb is that size will become progressively smaller as the system extends far- ther from the main source of supply. Trial pipe size may be arrived at by the following formula: Line J: (Pressure available to overcome pipe friction) x 100/equivalent length of run total developed length to most remote fixture x percentage factor of 1.5 (note: a per- centage factor is used only as an estimate for friction losses imposed for fittings for initial trial pipe size) = psi (average pressure drops per 100 feet of pipe). For trial pipe size see Figure E 103.3(3) (Type L copper) based on 2.77 psi and a 108 glint = 2'/z inches. To deter- mine the equivalent length of run to the most remote out- let, the developed length is determined and added to the friction losses for fittings and valves. The developed lengths of the designated pipe sections are as follows: A-B 54ft B-C 8it C-D 13it D-E 150ft Total developed length = 225 it The equivalent length of the friction loss in fittings and valves must be added to the developed length (most remote outlet). Where the size of fittings and valves is not known, the added friction loss should be approximated. A general rule that has been used is to add 50 percent of the developed length to allow for fittings and valves. For example, the equivalent length of run equals the developed length of run (225 for x 1.5 = 338 ft). The total equivalent length of run for determining a trial pipe size is 338 feet. Example: 9.36 (pressure available to overcome pipe friction) x 100/ 338 (equivalent length of run = 225 x 1.5) = 2.77 psi (average pressure drop per 100 feet of pipe). Step 7 Column 6: Select from Table E103.3(6) the equivalent lengths for the trial pipe size of fittings and valves on each pipe section. Enter the sum for each section in Column 6. (The number of fittings to be used in this example must be an estimate.) The equivalent length of piping is the devel- oped length plus the equivalent lengths of pipe corre- sponding to friction head losses for fittings and valves. Where the size of fittings and valves is not known, the added friction head losses must be approximated. An esti- mate for this example is found in Table E.1. 128 2012 INTERNATIONAL PLUMBING CODE" C,Ty,ght @ ON I ICC ALL RIGHTS RESERVED Awsed by ().(-)O,d,,Nombsx 100760189 oc Sep SO, 2019 m. oo To (PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, S I ( [IFodUt.. byzoyUb,dparty.oPAembmoo Uoosd Single—oPIA PTymg PodortxodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE PBDREAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER APPENDIX E TABLE EA COLD WATER PIPE SECTION FITTINGSIVALVES PRESSURE LOSS EXPRESSED AS EQUIVALENT LENGTH OF TUBE (feet) HOT WATER PIPE SECTION FITTINGS/ VALVES PRESSURE LOSS EXPRESSED AS EQUIVALENT OF TUBE (feet) A-B 3-2'/z" Gate valves 3 A-B 3-2'/z" Gate valves 3 1-2'/z" Side branch tee 12 1-2'/z" Side branch tee 12 B-C 1-2'/z" Straight run tee 0.5 B-C 1-2" Straight run tee 7 1-2" 90-degree ell 0.5 C-F 1-2'/z" Side branch tee 12 C-F 1-1'/z" Side branch tee 7 C-D 1-2'/z" 90-degree ell 7 C-D 1-'/," 90-degree ell 4 D-E 1-2'/z" Side branch tee 12 D-E 1-1'/z" Side branch tee 7 For SI 1 foot - 304 8 mm, i inch - 25 4 mm Step 8 Column 7: Add the figures from Column 4 and Column 6, and enter in Column 7.

Maximum friction head loss per 100 feet is determined on the basis of total pressure available for fric- tion head loss and the longest equivalent length of run. The selection is based on the gallon -per -minute demand, the uniform friction head loss, and the maximum design velocity. Where the size indicated by hydraulic table indi- cates a velocity in excess of the selected velocity, a size must be selected which produces the required velocity. Step 10 Column 9: Multiply the figures in Columns 7 and 8 for each section and enter in Column 9. Total friction loss is determined by multiplying the friction loss per 100 feet (30 480 min) for each pipe section in the total developed length by the pressure loss in fittings expressed as equivalent length in feet. Note: Section C-F should be considered in the total pipe friction losses only if greater loss occurs in Section C-F than in pipe section D-E. Section C-F is not considered in the total developed length. Total friction loss in equivalent length is deter- mined in Table E.2. Step 11 Line K: Enter the sum of the values in Column 9. The value is the total friction loss in equivalent length for each designated pipe section. Step 12 Line L: Subtract Line J from Line K and enter in Column 10. TABLE E.2 The result should always be a positive or plus figure. If it is not, repeat the operation using Columns 5, 6, 8 and 9 until a balance or near balance is obtained. If the differ- ence between Lines J and K is a high positive number, it is an indication that the pipe sizes are too large and should be reduced, thus saving materials. In such a case, the opera- tions using Columns 5, 6, 8 and 9 should again be repeated. The total friction losses are determined and subtracted from the pressure available to overcome pipe friction for trial pipe size. This number is critical as it provides a guide to whether the pipe size selected is too large and the pro- cess should be repeated to obtain an economically designed system. Answer: The final figures entered in Column 5 become the design pipe size for the respective sections. Repeating this operation a second time using the same sketch but considering the demand for hot water, it is possible to size the hot water distribution piping. This has been worked up as a part of the overall problem in the tabular arrangement used for sizing the service and water distribution piping.

The minimum size water service pipe shall be 3/q inch (19.1 mm). The size of water service mains, branch mains and risers shall be determined according to water supply demand [gpm (L/m)], available water pressure [psi (kPa)] and friction loss due to the water meter and developed length of pipe [feet (m)], including equivalent length of fittings. The size of each water distribution system shall be determined according to the procedure outlined in this section or by other design methods conforming to acceptable engineering prac- tice and approved by the code official: 1. Supply load in the building water -distribution system shall be determined by total load on the pipe being sized, in terms of water -supply fixture units (w.s.f.u.), as shown in Table E103.3(2). For fixtures not listed, choose a w.s.f.u. value of a fixture with similar flow characteristics. 2. Obtain the minimum daily static service pressure [psi (kPa)] available (as determined by the local water authority) at the water meter or other source of supply at the installation location. Adjust this minimum daily static pressure [psi (kPa)] for the following conditions: 2.1. Determine the difference in elevation between the source of supply and the highest water sup- ply outlet. Where the highest water supply out- let is located above the source of supply, deduct 0.5 psi (3.4 kPa) for each foot (0.3 m) of differ- ence in elevation. Where the highest water sup- ply outlet is located below the source of supply, add 0.5 psi (3.4 kPa) for each foot (0.3 m) of difference in elevation. 2.2. Where a water pressure reducing valve is installed in the water distribution system, the minimum daily static water pressure available is 80 percent of the minimum daily static water pressure at the source of supply or the set pres- sure downstream of the pressure reducing valve, whichever is smaller. 2.3. Deduct all pressure losses due to special equip- ment such as a backflow preventer, water filter and water softener. Pressure loss data for each piece of equipment shall be obtained through the manufacturer of such devices. 2.4. Deduct the pressure in excess of 8 psi (55 kPa) due to installation of the special plumbing fix- ture, such as temperature controlled shower and flushometer tank water closet. Using the result- ing minimum available pressure, find the corre- sponding pressure range in Table E201.1. 3. The maximum developed length for water piping is the actual length of pipe between the source of supply and the most remote fixture, including either hot (through the water heater) or cold water branches multiplied by a factor of 1.2 to compensate for pressure loss through fittings. Select the appropriate column in Table E201.1 equal to or greater than the calculated maximum devel- oped length. 4. To determine the size of water service pipe, meter and main distribution pipe to the building using the appro- priate table, follow down the selected "maximum developed length' column to a fixture unit equal to, or greater than the total installation demand calculated by using the "combined" water supply fixture unit column of Table E103.3(2). Read the water service pipe and meter sizes in the first left-hand column and the main distribution pipe to the building in the second left-hand column on the same row. 5. To determine the size of each water distribution pipe, start at the most remote outlet on each branch (either hot or cold branch) and, working back toward the main distribution pipe to the building, add up the water sup- ply fixture unit demand passing through each segment of the distribution system using the related hot or cold column of Table E103.3(2). Knowing demand, the size of each segment shall be read from the second left-hand column of the same table and maximum developed length column selected in Steps 1 and 2, under the same or next smaller size meter row. In no case does the size of any branch or main need to be larger that the size of the main distribution pipe to the building established in Step 4. SECTION E202 DETERMINATION OF PIPE VOLUMES E202.1 Determining volume of piping systems.

SECTION F101 CUTTING, NOTCHING AND BORING IN WOOD MEMBERS [B] F101.1 Joist notching. Notches on the ends of joists shall not exceed one-fourth the joist depth. Holes bored in joists shall not be within 2 inches (51 mm) of the top or bottom of the joist, and the diameter of any such hole shall not exceed one-third the depth of the joist. Notches in the top or bottom of joists shall not exceed one sixth the depth and shall not be located in the middle third of the span. [B] F101.2 Stud cutting and notching. In exterior walls and bearing partitions, any wood stud is permitted to be cut or notched to a depth not exceeding 25 percent of its width. Cut- ting or notching of studs to a depth not greater than 40 per- cent of the width of the stud is permitted in nonbearing partitions supporting no loads other than the weight of the partition. [B] F101.3 Bored holes. A hole not greater in diameter than 40 percent of the stud width is permitted to be bored in any wood stud. Bored holes not greater than 60 percent of the width of the stud are permitted in nonbearing partitions or in any wall where each bored stud is doubled, provided not more than two such successive doubled studs are so bored. In no case shall the edge of the bored hole be nearer than 0.625 inch (15.9 mm) to the edge of the stud. Bored holes shall not be located at the same section of stud as a cut or notch. [B] F101.4 Cutting, notching and boring holes in struc- tural steel framing. The cutting, notching and boring of holes in structural steel framing members shall be as pre- scribed by the registered design professional. [B] F101.5 Cutting, notching and boring holes in cold - formed steel framing. Flanges and lips of load -bearing cold - formed steel framing members shall not be cut or notched. Holes in webs of load -bearing cold -formed steel framing members shall be permitted along the centerline of the web of the framing member and shall not exceed the dimensional limitations, penetration spacing or minimum hole edge dis- tance as prescribed by the registered design professional. Cut- ting, notching and boring holes of steel floor/roof decking shall be as prescribed by the registered design professional. [B] F101.6 Cutting, notching and boring holes in non- structural cold -formed steel wall framing. Flanges and lips of nonstructural cold -formed steel wall studs shall not be cut or notched. Holes in webs of nonstructural cold -formed steel wall studs shall be permitted along the centerline of the web of the framing member, shall not exceed P/, inches (38 mm) in width or 4 inches (102 mm) in length, and the holes shall not be spaced less than 24 inches (610 mm) center to center from another hole or less than 10 inches (254 mm) from the bearing end. 2012 INTERNATIONAL PLUMBING CODE" 147

The International Private Sewage Disposal Code, in this 2012 edition, is designed to meet these needs through model code regula- tions that safeguard the public health and safety in all communities, large and small. This comprehensive sewage disposal code establishes minimum regulations for sewage disposal systems using prescriptive and performance -related provisions. It is founded on broad -based princi- ples that make possible the use of new materials and new sewage disposal designs. This 2012 edi- tion is fully compatible with all of the International Codes (I -Codes) published by the International Code Council (ICC), including the International Building Code, International Energy Conservation Code, International Existing Building Code, International Fire Code International Fuel Gas Code, International Green Construction Code TM (to be available March 2012), Interna- tional Mechanical Code ICC Performance Code, International Plumbing Code, International Property Maintenance Code International Residential Code International Swimming Pool and Spa Code TM (to be available March 2012), International Wildland-Urban Interface Code and Inter- national Zoning Code. The International Private Sewage Disposal Code provisions provide many benefits, among which is the model code development process that offers an international forum for plumbing profession- als to discuss performance and prescriptive code requirements. This forum provides an excellent arena to debate proposed revisions. This model code also encourages international consistency in the application of provisions. The first edition of the International Private Sewage Disposal Code (1995) was the culmination of an effort initiated in 1994 by a development committee appointed by the ICC and consisting of repre- sentatives of the three statutory members of the International Code Council at that time, including: Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). The intent was to draft a comprehensive set of regulations for sewage disposal systems consistent with and inclu- sive of the scope of the existing model codes. Technical content of the latest model codes promul- gated by BOCA, ICBO and SBCCI was used as the basis for the development. This 2012 edition presents the code as originally issued, with changes reflected in the 1997 through 2009 editions and further changes approved through the ICC Code Development Process through 2010. A new edition such as this is promulgated every three years. This code is founded on principles intended to establish provisions consistent with the scope of a sewage disposal code that adequately protects public health, safety and welfare; provisions that do not unnecessarily increase construction costs; provisions that do not restrict the use of new materi- als, products or methods of construction; and provisions that do not give preferential treatment to particular types or classes of materials, products or methods of construction. The International Private Sewage Disposal Code is available for adoption and use by jurisdictions internationally. Its use within a governmental jurisdiction is intended to be accomplished through adoption by reference in accordance with proceedings establishing the jurisdiction's laws. At the time of adoption, jurisdictions should insert the appropriate information in provisions requiring spe- cific local information, such as the name of the adopting jurisdiction. These locations are shown in bracketed words in small capital letters in the code and in the sample ordinance. The sample adop- tion ordinance on page xi addresses several key elements of a code adoption ordinance, including the information required for insertion into the code text. 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® iii I " ' CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m.00 PM(PDT)p—Potto IL eAgemt,oUICC No FYUPep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Maintenance The International Private Sewage Disposal Code is kept up to date through the review of proposed changes submitted by code enforcing officials, industry representatives, design professionals and other interested parties. Proposed changes are carefully considered through an open code develop- ment process in which all interested and affected parties may participate. The contents of this work are subject to change both through the Code Development Cycles and the governmental body that enacts the code into law. For more information regarding the code development process, contact the Codes and Standards Development Department of the Interna- tional Code Council. While the development procedure of the International Private Sewage Disposal Code assures the highest degree of care, ICC, its members and those participating in the development of this code do not accept any liability resulting from compliance or noncompliance with the provisions because ICC and its founding members do not have the power or authority to police or enforce compliance with the contents of this code. Only the governmental body that enacts the code into law has such authority. Code Development Committee Responsibilities (Letter Designations in Front of Section Numbers) In each code development cycle, proposed changes to this code are considered at the Code Devel- opment Hearing by the International Plumbing Code Development Committee, whose action consti- tutes a recommendation to the voting membership for final action on the proposed change. Proposed changes to a code section that has a number beginning with a letter in brackets are con- sidered by a different code development committee. For example, proposed changes to code sec- tions that have [B] in front of them (e.g., [B] 309.2) are considered by one of the International Building Code Development Committees (IBC -General) at the Code Development Hearings. The content of sections in this code that begin with a letter designation is maintained by another code development committee in accordance with the following: [A] = Administrative Code Development Committee; [B] = International Building Code Development Committee (IBC -Fire Safety, General, Means of Egress or Structural); and [P] = International Plumbing Code Development Committee. Note that, for the development of the 2015 edition of the I -Codes, there will be two groups of code development committees and they will meet in separate years. The groupings are as follows: Group A Codes (Heard in 2012, Code Change Proposals Deadline: January 3, 2012) Group B Codes (Heard in 2013, Code Change Proposals Deadline: January 3, 2013) International Building Code Administrative Provisions (Chapter 1 all codes except IRC, administrative updates to currently referenced standards, and designated definitions) International Fuel Gas Code International Energy Conservation Code International Mechanical Code International Existing Building Code International Plumbing Code International Fire Code International Private Sewage Disposal Code International Green Construction Code ICC Performance Code International Property Maintenance Code International Residential Code International Swimming Pool and Spa Code International Wildland-Urban Interface Code International Zoning Code iv 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® " ' CoTy,ght @ ON I ICC ALL RIGHTS RESERVED A-P—d by ().(-)O,d,,Nomb,x1oovco189 oc Sep 9o.2o19 m. oo PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, rk S I ( ,Fod,Yo,,bymytl,dputy,o,ANb�to,au o,sd Single —oPIA PTymg anodmgp� dortuokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,EDERAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Code change proposals submitted for code sections that have a letter designation in front of them will be heard by the respective committee responsible for such code sections. Because differ- ent committees will hold its code development hearings in different years, it is possible that some proposals for this code will be heard by a committee in a different year than the year in which the primary committee for this code meets. For instance, every section of Chapter 1 of this code is designated as the responsibility of the Administrative Code Development Committee, and that committee is part of the Group B portion of the hearings. This committee will hold its code development hearings in 2013 to consider all code change proposals for Chapter 1 of this code and proposals for Chapter 1 of all I -Codes except the International Residential Code and ICC Performance Code. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Administrative Code Development Committee for con- sideration in 2013. It is very important that anyone submitting code change proposals understand which code devel- opment committee is responsible for the section of the code that is the subject of the code change proposal. For further information on the code development committee responsibilities, please visit the ICC web site at www.iccsafe.org/scoping. Marginal Markings Italicized Terms Solid vertical lines in the margins within the body of the code indicate a technical change from the requirements of the 2009 edition.

Where a building cannot be served by a public sewer system, the building site must be pro- vided with a system for treating the waste water generated from the use of plumbing fixtures in the building. The IPSDC addresses site evaluations, materials, various soil absorption systems, holding tanks, cesspools and onsite waste water treatment systems. The IPSDC provides a total approach for the onsite, safe disposal of the waste flow discharged to the plumbing fixtures in a building. The IPSDC is a specification- (prescriptive- ) oriented code with very few occurrences of perfor- mance -oriented text. The site soil must be evaluated in a prescribed manner to determine its ability to accept the waste flow. The chosen waste treatment method must be designed in a prescribed manner for the soil conditions at the building site, constructed using prescribed materials and installed according to prescribed dimensions. The IPSDC sets forth the minimum acceptable require- ments for private sewage disposal systems in order to protect humans and the environment from insanitary conditions that would develop if waste flows were not rendered harmless. Arrangement and Format of the 2009 IPSDC The format of the IPSDC allows each chapter to be devoted to a particular subject with the excep- tion of Chapter 3 which contains general subject matters that are not extensive enough to warrant their own independent chapter. The IPSDC is divided into 11 different parts: Chapters Subjects 1-2 Administration and Definitions 3 General Regulations 4 Site Evaluation and Requirements 5 Materials 6, 7, 9 &10 Effluent Absorption and Distribution Systems 8 Tanks 11 Waste Water Treatment Systems 12 Inspections 13 Nonliquid Saturated Treatment Systems 14 Referenced Standards Appendices A & B Appendices The following is a chapter -by -chapter synopsis of the scope and intent of the provisions of the International Private Sewage Disposal Code: Chapter 1 Scope and Administration. This chapter contains provisions for the application, enforcement and administration of subsequent requirements of the code. In addition to establish- ing the scope of the code, Chapter 1 identifies which buildings and structures come under its pur- view. Chapter 1 is largely concerned with maintaining "due process of law" in enforcing the requirements contained in the body of this code. Only through careful observation of the adminis- trative provisions can the building official reasonably expect to demonstrate that "equal protection under the law" has been provided. Chapter 2 Definitions. Chapter 2 is the repository of the definitions of terms used in the body of the code. Codes are technical documents and every word, term and punctuation mark can impact the meaning of the code text and the intended results. The code often uses terms that have a unique meaning in the code and the code meaning can differ substantially from the ordinarily understood meaning of the term as used outside of the code. 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® vii I i i i CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m. oo PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER The terms defined in Chapter 2 are deemed to be of prime importance in establishing the mean- ing and intent of the code text. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and the user may not be aware that a term is defined. Where understanding of a term's definition is especially key to or necessary for understanding of a particular code provision, the term is shown in italics wherever it appears in the code. This is true only for those terms that have a meaning that is unique to the code. In other words, the generally understood meaning of a term or phrase might not be sufficient or consistent with the meaning pre- scribed by the code; therefore, it is essential that the code -defined meaning be known. Guidance regarding tense, gender and plurality of defined terms, as well as guidance regarding terms not defined in this code, is provided. Chapter 3 General Regulations. The content of Chapter 3 is often referred to as "miscella- neous," rather than general regulations. Chapter 3 received that label because it is the only chapter in the code whose requirements do not interrelate. If a requirement cannot be located in another chapter, it can be found in this chapter. Specific requirements concerning flood hazard areas are in this chapter. Chapter 4 Site Evaluation and Requirements. A private sewage disposal system has an efflu- ent which cannot be directly discharged into waterways or open ponds. Soil of the right consistency and water content provides a natural filtering and treatment of this discharge. Because soil condi- tions vary widely, even on the same building site, tests and inspections of the soils must be per- formed to evaluate the degree to which the soil can accept these liquids. The results of the tests provide necessary information to design an adequate private sewage disposal system. Chapter 4 provides the methods for evaluating the building site. Chapter 5 Materials. Private sewage disposal systems depend on the strength, quality and chemical resistance of the components that make up the system. To that end, the purpose of Chap- ter 5 is to specify the minimum material and component standards to ensure that the private sew- age disposal system will correctly perform for its intended life. Chapter 6 Soil Absorption Systems. The design of soil absorption systems depends heavily on the result of the tests and evaluation of the site soil conditions required in Chapter 4. Where soil is less permeable, the area of the soil absorption must be large as compared to that required for soils that are highly permeable. The type of building that is being served by the private sewage disposal system also affects the size of the planned soil absorption area. This chapter provides the methods for computingthe required absorption area and details for the proper installation of the soil absorp- tion systems. Chapter 7 Pressure Distribution Systems. Chapter 6 deals with gravity -type soil absorption systems or systems where the effluent is allowed to drain out of the distribution piping by gravity. This chapter offers an alternative method of discharging the effluent into the ground by pressure means. As such, Chapter 7 provides the necessary details for designing the piping and pumping sys- tems for pressure distribution systems. Chapter 8 Tanks. Tanks are an integral part of any private sewage disposal system whether they serve as treatment (septic) tanks or merely just holding tanks for leveling the peaks in flow to the system. Where tanks are used for treatment, the dimensions, volume and location of internal fea- tures are very important to ensure that the solid wastes are kept within the tank so as to not clog the effluent distribution system. Where tanks are used for holding purposes, they must be sized large enough to accommodate the total of peak flows coming from a building. Chapter 8 provides the necessary requirements for tanks. Chapter 9 Mound Systems. Mound systems are another method for applying the effluent from a private sewage disposal system to the soil. This type of system may be advantageous in some localities due to the existing soil conditions. Chapter 9 has specific requirements for soil and site evaluations for mound systems. viii 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® S i l i Copy,ghtOo O N I ICC ALL RIGHTS RESERVED Awsed by ().(-)O,d,,Nombsx 100760189 oc Sep 9o.2o19 m. oo PM(PDT) p—Potto l»eAge mt,oUICC No FYUP ep,odw.noa oAYUP, iff I ( N ,Fod,Yo,,bymytl,dputy,o,Abau�to,o,sd Single —oPIA PTymg anodmgp� dortuokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE ,ED REAL COPYRIGHT 11 AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER Chapter10 Cesspools. Although prohibited from being installed as a permanent private sewage disposal system, cesspools may be necessary where permanent systems are under repair, or are being built. Chapter 10 provides the details for constructing a cesspool. Chapter 11 Residential Waste Water Systems. Another method of private sewage disposal is a small waste water treatment plant. Where permitted, these systems can discharge effluent directly to streams and rivers. Chapter 11 specifies the standard to which waste water treatment plants must conform. Chapter 12 Inspections. The best soil and site analysis along with the best design will be ren- dered useless if the system is not installed according to the plans for the system. Chapter 12 pro- vides requirements for inspection of private sewage disposal systems. Chapter 13 Nonliquid Saturated Treatment Systems. In some locations, water for the flushing of wastes into and through a sanitary piping system is not available. For example, a toilet facility provided for a remote campground without running water would require such a system. Chapter 13 specifies the standard to which nonliquid saturated treatment systems must conform. Chapter 14 Referenced Standards. The code contains numerous references to standards that are used to regulate materials and methods of construction. Chapter 14 contains a comprehensive list of all standards that are referenced in the code. The standards are part of the code to the extent of the reference to the standard. Compliance with the referenced standard is necessary for compli- ance with this code. By providing specifically adopted standards, the construction and installation requirements necessary for compliance with the code can be readily determined. The basis for code compliance is, therefore, established and available on an equal basis to the code official, contractor, designer and owner. Chapter 14 is organized in a manner that makes it easy to locate specific standards. It lists all of the referenced standards, alphabetically, by acronym of the promulgating agency of the standard. Each agency's standards are then listed in either alphabetical or numeric order based upon the stan- dard identification. The list also contains the title of the standard; the edition (date) of the standard referenced; any addenda included as part of the ICC adoption; and the section or sections of this code that reference the standard. Appendix A System Layout Illustrations. Because each chapter of this code uses only words to describe requirements, illustrations can offer greater insight as to what the words mean. Appen- dix A has a number of illustrations referenced to specific sections of the code to help the reader gain a better understanding of the code's requirements. Appendix B Tables for Pressure Distribution Systems. The design of a pressure distribution system is accomplished by the use of several complex formulas found in Chapter 7. Because a user of the code may not have the necessary experience to manipulate the formulas, a tabular approach for designing pressure distribution systems is provided in Appendix B. 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® ix I i l i CoTy,ght @ zoI I ICC ALL RIGHTS RESERVED Awsedby().(-)O,d,,Nombsx1oovco189 oc SIP so.2.o19 m. oo PM (PDT) p—Potto l»eAge mt,oUICC No FYUP ep,oddtoaoAYUP, (,,Fod,Yo¢ebymytl,dputy,o,ANb,to,au o,sd Single —oPIA opymg PodortuodmgFokbad ANY VNAVTHORIVED REPRODUCTION REDISTRIBUTION IS A VIOLATION OF THE FEDERAL COPYRIGHT ACT AND THE LICENSE AGREEMENT, AND SUBJECT TO CIVIL AND CRIMINAL PENALTIES THEREUNDER 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL CODE® Co,gbt OO?.ot I ICC ALL RIGHTS RESERVED Awsed by ().

Contrast refers to the difference in color between the soil mottle and the background color of the soil and is described as "faint" if the mottle is evident but recogniz- able with close examination; "distinct" if the mottle is readily seen but not striking; or "prominent" if the mottle is obvious and one of the outstanding features of the hori- zon. The color(s) of the mottle(s) shall be indicated. 403.1.5 Observed ground water. The depth to ground water, if present, shall be reported. Observed ground water shall be reported at the level that ground water reaches in the soil borehole or the highest level of sidewall seepage into the boring. Measurements shall be made from ground level. Soil located above the water level in the boring shall be checked for the presence of soil mottles. 403.2 Color patterns not indicative of soil saturation. The following soil conditions shall be reported, but shall not be interpreted as color patterns caused by wetness or saturation. Soil profiles with an abrupt textural change with finer -tex- tured soils overlying more than 4 feet (1219 mm) of unmot- tled, loamy sand or coarser soils can have a mottled zone for the finer textured material. Where the mottled zone is less than 12 inches (305 mm) thick and located immediately above the textural change, a soil absorption system shall be permitted in the loamy sand or coarser material below the mottled layer. The site shall be considered unsuitable where any soil mottles occur within the sandy material. The code official shall consider certain coarse sandy loam soils to be included as a coarse material. 403.2.1 Other soil color patterns. Soil mottles occur that are not caused by seasonal or periodic soil saturation zones. Examples of such soil conditions not limited by enumeration are soil mottles formed from residual sand- stone deposits; soil mottles formed from uneven weather- ing of glacially deposited material or glacially deposited material that is naturally gray in color, including any con- cretionary material in various stages of decomposition; deposits of lime in a profile derived from highly calcare- ous parent material; light-colored silt coats deposited on soil bed faces; and soil mottles usually vertically oriented along old or decayed root channels with a dark organic stain usually present in the center of the mottled area. 403.2.2 Reporting exceptions. The site evaluator shall report any mottled soil condition. The observation of soil mottles not caused by soil saturation shall be reported. Upon request, the code official shall make a determination of the acceptability of the site. 403.3 Bedrock. The depth of the bedrock, except sandstone, shall be established at the depth in a soil boring where more than 50 percent of the weathered -in -place material is consoli- dated. Sandstone bedrock shall be established at the depth where an increase in resistance to penetration of a knife blade occurs. 403.4 Alluvial and colluvial deposits. Subsurface soil absorption systems shall not be placed in alluvial and collu- vial deposits with shallow depths, extended periods of satura- tion or possible flooding. SECTION 404 PERCOLATION OR PERMEABILITY EVALUATION 404.1 General. The permeability of the soil in the proposed absorption system shall be determined by percolation tests or permeability evaluation. 404.2 Percolation tests and procedures. At least three per- colation tests in each system area shall be conducted. The holes shall be spaced uniformly in relation to the bottom depth of the proposed absorption system. More percolation tests shall be made where necessary, depending on system design. 404.2.1 Percolation test hole. The test hole shall be dug or bored. The test hole shall have vertical sides and a hori- zontal dimension of 4 inches to 8 inches (102 mm to 203 mm). The bottom and sides of the hole shall be scratched with a sharp -pointed instrument to expose the natural soil. All loose material shall be removed from the hole, and the bottom shall be covered with 2 inches (51 mm) of gravel or coarse sand. 404.2.2 Test procedure, sandy soils. The hole shall be filled with clear water to a minimum of 12 inches (305 mm) above the bottom of the hole for tests in sandy soils. The time for this amount of water to seep away shall be determined and this procedure shall be repeated if the water from the second filling of the hole seeps away in 10 minutes or less. The test shall proceed as follows: Water shall be added to a point not more than 6 inches (152 mm) above the gravel or coarse sand. Thereupon, from a fixed reference point, water levels shall be measured at 10-min- ute intervals for a period of 1 hour. Where 6 inches (152 mm) of water seeps away in less than 10 minutes, a shorter interval between measurements shall be used, but in no case shall the water depth exceed 6 inches (152 min). Where 6 inches (152 mm) of water seeps away in less than 2 minutes, the test shall be stopped and a rate of less than 3 minutes per inch (7.2 s/mm) shall be reported. The final water level drop shall be used to calculate the percolation rate. Soils not meeting the above requirements shall be tested in accordance with Section 404.2.3. 404.2.3 Test procedure, other soils. The hole shall be filled with clear water, and a minimum water depth of 12 inches (305 mm) shall be maintained above the bottom of the hole for a 4-hour period by refilling whenever neces- sary or by use of an automatic siphon. Water remaining in the hole after 4 hours shall not be removed. Thereafter, the soil shall be allowed to swell not less than 16 hours or more than 30 hours. Immediately after the soil swelling period, the measurements for determining the percolation rate shall be made as follows: Any soil sloughed into the hole shall be removed, and the water level shall be adjusted to 6 inches (152 mm) above the gravel or coarse sand. Thereupon, from a fixed reference point, the water level shall be measured at 30-minute intervals for a period of 4 hours, unless two successive water level drops do not vary by more than '/,s inch (1.59 min).

The hole shall be filled with clear water to a point not more than 6 inches (152 mm) above the gravel or coarse sand whenever it becomes nearly empty. The water level shall not be adjusted during the three measurement periods except to the limits of the last measured water level drop. When the first 6 inches (152 mm) of water seeps away in less than 30 minutes, the time interval between measurements shall be 10 minutes and the test run for 1 hour. The water depth shall not exceed 5 inches (127 mm) at any time during the measurement period. The drop that occurs during the final measurement period shall be used in calculating the perco- lation rate. 404.2.4 Mechanical test equipment Mechanical percola- tion test equipment shall be of an approved type. 404.3 Permeability evaluation. Soil shall be evaluated for estimated percolation based on structure and texture in accor- dance with accepted soil evaluation practices. Borings shall be made in accordance with Section 404.2 for evaluating the soil. SECTION 405 SOIL VERIFICATION 405.1 Verification. Where required by the code official, depth to soil mottles, depth to high ground water, soil tex- tures, depth to bedrock and land slope shall be verified by the code official. The code official shall require, where neces- sary, backhoe pits to be provided for verification of soil bor- ing data. Where required by the code official, the results of percolation tests or permeability evaluation shall be subject to verification. The code official shall require, where necessary, that percolation tests be conducted under supervision. Where the natural soil condition has been altered by filling or other methods used to improve wet areas, the code official shall require, where necessary, observation of high ground water levels under saturated soil conditions. Detailed soil maps, or other adequate information, shall be used for determining estimated percolation rates and other soil characteristics. 405.2 Monitoring ground water levels. A property owner or developer shall have the option to provide documentation that soil mottling or other color patterns at a particular site are not an indication of seasonally saturated soil conditions of high ground water levels. Direct observation shall be used to docu- ment ground water levels. Monitoring shall be in accordance with the procedures cited in Sections 405.2.1 through 405.2.6. 405.2.1 Precipitation. Monitoring shall be performed at a time of the year when maximum ground water elevation occurs. In determining whether a near -normal season has occurred where sites are subject to broad regional water tables, such as large areas of sandy soils, the fluctuation over the several -year cycle shall be considered. In such cases, data obtained from the United States Geological Survey (USGS) shall be used to determine if a regional water table was at or near its normal level. 405.2.2 Artificial drainage. Areas to be monitored shall be checked for drainage tile and open ditches that alter nat- ural high ground water levels. Where such factors are involved, information on the location, design, ownership and maintenance responsibilities for such drainage shall be provided. Documentation shall be provided to show that the drainage network has an adequate outlet and will be maintained. Sites affected by agricultural drain tile shall not be acceptable for system installation. 405.2.3 Procedures. The owner or the owner's agent shall notify the code official in writing of the intent to monitor. Where necessary, the code official shall field check the monitoring at least once during the time of expected satu- rated soil conditions. At least three wells shall be monitored at a site for a proposed system and replacement. Where necessary, the code official shall require more than three monitoring sites, and the site evaluator shall be so advised in writing. 405.2.4 Monitoring well design. At least two wells shall extend to a depth of at least 6 feet (1829 mm) below the ground surface and shall be a minimum of 3 feet (914 mm) below the designed system depth. However, with layered mottled soil over permeable unmottled soil, at least one well shall terminate within the mottled layer. Monitoring at greater depths shall be required, where necessary, due to site conditions. The site evaluator shall determine the depth of the monitoring wells for each specific site. All depths shall be approved. The monitoring well shall be a solid pipe installed in a bore hole. The pipe size shall be a minimum of 1 inch (25 mm) and a maximum of 4 inches (102 min). The bore hole shall be a minimum of 4 inches (102 mm) and a maximum of 8 inches (203 mm) larger than the pipe (see Appendix A, Figure A-2). 405.2.5 Observations. The first observation shall be made on or before [DATE]. Observations shall be made thereafter every 7 days or less until [DATE] or until the site is deter- mined to be unacceptable, whichever occurs first. Where water is observed above the critical depth at any time, an observation shall be made 1 week later. Where water is present above the critical depth at both observations, mon- itoring shall cease and the site shall be considered unac- ceptable. Where water is not present above the critical depth at the second observation, monitoring shall continue until [DATE]. Where any two observations 7 days apart show the presence of water above the critical depth, the site shall be considered unacceptable and the code official shall be notified in writing. When rainfall of 0.5 inch (12.7 mm) or more occurs in a 24-hour period during monitor- ing, observations shall be made at more frequent intervals, where necessary. 405.2.6 Reporting data. Where monitoring shows satu- rated conditions, the following data shall be submitted in writing: test locations; ground elevations at the wells; soil profile descriptions; soil series, if available from soil maps; dates observed; depths to observed water; and local precipitation data -monthly from [DATE] and daily during monitoring.

A request to install a soil absorption system shall be made in accor- dance with Section 106. SECTION 406 SITE REQUIREMENTS 406.1 Soil absorption site location. The surface grade of all soil absorption systems shall be located at a point lower than the surface grade of any nearby water well or reservoir on the same or adjoining property. Where this is not possible, the site shall be located so surface water drainage from the site is not directed toward a well or reservoir. The soil absorption system shall be located with a minimum horizontal distance between various elements as indicated in Table 406.1. Private sewage disposal systems in compacted areas, such as parking lots and driveways, are prohibited. Surface water shall be diverted away from any soil absorption site on the same or neighboring lots.

There shall be a minimum of 3 feet (914 mm) of soil between the bottom of the soil absorption system and high ground water or bedrock. Soil with a percolation rate of 60 minutes per 1 inch (25 mm) or faster shall exist for the depth of the proposed soil absorption system and at least 3 feet (914 mm) below the proposed bottom of the soil absorption system. There shall be 56 inches (1422 mm) of suitable soil from original grade for a conventional soil absorption system. 406.3 Percolation rate, trench or bed. A subsurface soil absorption system of the trench or bed type shall not be installed where the percolation rate for any one of the three tests is slower than 60 minutes for water to fall 1 inch (25 mm). The slowest percolation rate shall be used to determine the absorption area. 406.4 Percolation rate, seepage pit. Percolation tests shall be made in each horizon penetrated below the inlet pipe for a seepage pit. Soil strata in which the percolation rates are slower than 30 minutes per 1 inch (25 mm) shall not be included in computing the absorption area. The slowest per- colation rate shall be used to determine the absorption area. 406.5 Soil maps. When a parcel of land consists entirely of soils with very severe or severe limitations for on -site liquid - waste disposal as determined by use of a detailed soil map and supporting data, that map and supporting data shall be permitted to be used as a basis for denial for an on -site waste disposal system. However, the property owner shall be per- mitted to present evidence that a suitable site for an on -site liquid -waste disposal system does exist. 406.6 Filled area. A soil absorption system shall not be installed in a filled area unless written approval is received. 406.6.1 Placement of fill. The approval of a conventional soil absorption system shall be based on evidence indicat- ing its conformance to code requirements for area, perco- lation and elevation. 406.6.2 Bedrock.

TW= Total daily waste -water flow, gallons per day (L/day). W = Total mound width, feet (mm). X = Slope, percent. 903.2 Size of absorption area. The absorption area shall be sized based on the daily waste -water flow and the infiltrative capacity of the medium sand texture fill material, equaling 1.2 gallons per square foot (0.03 L/m') per day. The required absorption area shall be determined by the following equa- tion: AA = TW (Equation 9-1) ft 1.2 gal./2/day For SI: 1 square foot= 0.0929 m', 1 gallon = 3.785 L. 903.3 Trenches. Effluent shall be distributed in the mound through a trench system for slowly permeable soils with or without high ground water. Trench length shall be selected by determining the longest dimension perpendicular to any slope on the site. Trench width and spacing is dependent on specific site conditions. Trenches shall be 2 feet to 4 feet (610 mm to 1219 mm) wide. Trench length (B) shall be not more than 100 feet (2540 mm). Trenches shall be of equal length where more than one trench is required. A mound shall not have more than three trenches. Trench spacing (C) shall be deter- mined by the following equation: C= (Equation 9-2) Nx 0.24 gal./ft2/day x B For SI: 1 gallon = 3.785 L, 1 square foot= 0.0929 m'. TW The calculated trench spacing (C) shall be measured from center to center of the trenches. Facilities with more than 1,500 gallons (56 775 L) per day shall be specifically engi- neered and approved for use with a trench system. 903.4 Beds. A long, narrow bed design shall be used for per- meable soils with high water tables. The bed shall be square or rectangular for shallow permeable soils over bedrock. The bed length (B) shall be set after determining the longest dimension available and perpendicular to any slope on the site. 903.5 Mound dimensions. The mound height consists of the fill depth, bed or trench depth, the cap and topsoil depth. 903.5.1 Fill depth. The fill depth (D) shall be not less than 1 foot (305 mm) for slowly permeable soils and permeable soils with high water tables and not less than 2 feet (610 mm) of fill shall be required for shallow permeable soils over bedrock. Additional fill shall be placed at the downslope end of the bed or trench where the site is not level so the bottom of the bed or trenches is level. The downslope fill depth for bed systems shall be determined by the following equation: E= D+XA (Equation 9-3) For SI: 1 foot = 304.8 mm. The downslope fill depth for trench systems shall be determined by the following equation: E= D+ X (C+ A) (Equation 9-4) For SI: 1 foot = 304.8 mm. 903.5.2 Bed or trench depth. The bed or trench depth (T) shall be not less than 9 inches (229 mm) and not less than 6 inches (152 mm) of aggregate shall be placed under the distribution pipes and not less than 2 inches (51 mm) of aggregate shall be placed over the top of the distribution pipes. 903.5.3 Cap and topsoil depth. The cap and topsoil depth (H) at the center of the mound shall be not less than 18 inches (457 mm), which includes 1 foot (305 mm) of sub- soil and 6 inches (152 mm) of topsoil. Outer edges of the mound, G (the minimum cap and topsoil depth), shall be not less than 1 foot (305 mm), which includes 6 inches (152 mm) of subsoil and 6 inches (152 mm) of topsoil. The soil used for the cap shall be topsoil or finer textured subsoil. 903.5.4 Mound lengths. The total mound length (L) shall be determined by the following equation: L = B+ 2K (Equation 9-5) For SI: 1 foot = 304.8 mm. where: K = 3[(D 2 E) + F+ H] 36 2012 INTERNATIONAL PRIVATE SEWAGE DISPOSAL
