UTILITY SYSTEMS
UTILITY The City of Friendswood operates and maintains both a water
SYSTEMS system and a wastewater system. Future expansion to these systems
required to meet the community's future growth will be imple-
mented through the use,of impact fees. These fees, charged against
new development, will pay the cost for new facilities, but they
cannot be used for replacement costs. Therefore, costs associated
with upgrading the existing systems will require some other type of
funding source. The following sections discuss the existing features
of each system and proposed capital improvements as set forth in
the 1997 study which updated the City's impact fees.
WATER Water Source - The City has two sources for its water supply.
SYSTEM These sources are from ground water wells and surface water which
is purchased from the City of Houston. This water purchase is for
3.0 million gallons per day which is in excess of current needs. The
purchase was in response to direction by the Harris-Galveston
Coastal Subsidence District that the service area in which the City
of Friendswood is located would convert to the surface water supply
whereby 80 percent of the total demand would be served by surface
water and that a maximum of 20 percent of the total demand would
be served by the City's existing water wells. The City also has an
• agreement with the City of Houston to secure a second take point
for surface water when additional capacity is required. Based upon
cunent estimates, Friendswood will require an additiona12.3 MGD
� of surface water at build out. �
7.1
- Demand - In 1996, the City's average water consumption was
approximately 3.58 million gallons per day. Of the 10,011
connections, the customer connections were divided between 8,189
single family and 1,463 multi-family units. The remaining 359
connections were split among commercial (193), sprinkler systems
(119), and semi-public uses such as parks, schools and churches
(47). .
The system demand will exceed the available surface water capacity
in the future and the City of Friendswood will be acquiring
additional surface water from Houston. As of 1997, a study of the
water distribution system and additional surface water take point(s)
is underway but has not been completed. This study will determine
what improvements are needed to the City's water system and at
what point additional surface water will be required.
Distribution 5ystem - Figure 21 shows the present water distribu-
tion system. The system is primarily comprised of six and eight
inch lines. Major lines in the system are the following:
� A ten inch line is in Friendswood Drive east of Parkwood
Avenue to Viejo Drive near the eastern city limits.
• A twelve inch line is also in Parkwood Avenue south of
Friendswood Drive to within approximately one thousand feet
, of the southern city limits.
• From the intersection of Friendswood Drive and Parkwood
� Avenue, a fourteen iqch line in this right-of-way extends

easterly to the city limits.
• A ten inch line (with some 8-inch segments) is in Friendswood
Drive between Parkwood Avenue and Edgewood Drive.
� A twelve inch line(with some 8-inch segments) is in Blackhawk
Boulevard between Parkwood Avenue and Edgewood Drive.
• A twelve inch line from the ten inch line in Friendswood Drive
to the twelve inch in Parkwood Avenue.
The location of the larger trunk lines described above which are
located in the City's southeastern section will provide the opportuni-
ty to meet future growth and water demands in this area.
Completed projects associated with surface water are the transmis-
sion, pumping, and storage facilities which are expected to be
adequate'to serve the City's requirements to the time when approxi-
mately fifty percent of the City is built out. As the City approaches
this level of development, a second transmission line in Beamer
Road and Dixie Farm Road with associated pumping and storage
facilities is envisioned by the Ciry's engineers. Currently, an eight
inch line is located in the rights-of-way of Beamer and Edgewood
and tie to the twelve inch line in Blackhawk Boulevard.
. Future Improvements - There are three growth areas in the City
where future capital improvements are proposed for the water
system: the Melody Lane system, Bay Area Boulevard Service
- Area and the South Friendswood system.
7.3
• The Melody Lane area extends service into a vacant area of
approximately 400 acres between Melody Lane and Clear
Creek. The proposed eight and twelve inch lines tie to an eight
inch line in Melody Lane.
• Proposals for the South Friendswood System include the
looping of minor distribution lines which are comprised of eight
and twelve inch sizes within proposed residential developments.
This line network would serve approximately 1,088 acres.
• Proposals for the Bay Area Boulevard Area include construct-
ing of a 14-inch trunk line from Parkwood (along the Bay Area
Boulevard right-of-way) to the 10-inch line in Friendswood D-
rive. This would enable a second take point for surface water
to be located in the north portion of the city and the system
could them push water to the south.
WASTEWATER Treatment - The Blackhawk Regional Wastewater Treatment Plant
SYSTEM is located in Friendswood on Ciear Creek in the northeastern section
of the City. Friendswood owns 4.875 million gallons per day of the
plant total capacity. This capacity was purchased in two phases.
Phase I provided 2.375 million gallons per day and this capacity is
serving present development. An additional 2.5 million gallons per
day was obtained by the City in the Phase II construction and is
available to serve future development. This capacity will serve the
, City through the ten-year capital improvements set forth in the
impact fee study, from 1997 - 2007.
= In 1996, the number of equivalent units was estimated to be 9,850
7.4
for wastewater treatment purposes. Using an average daily demand
of 100 gallons per capita per unit and the 1990 census data of an
average of 2.86 persons per unit, the 1996 estimate of capacity
utilized at the Blackhawk Plant is 2.817 million gallons per day.
Based upon same criteria, the capacity required of the plant at
buildout, assuming 17,500 equivalent units, would be 5 million
gallons per day. Assuming no adjustment to usage per capita or the
number of persons per unit, the City would be required to purchase
a small amount of additional capacity (estimated population is
48,600). '
Collection System - This system is shown by Figure 22, Sewer
Utility. Most collection lines in the system which service the
adjoining properties are six and eight inches in size. Trunk lines
range upward from twelve inches to thirty-six inches. Not all areas
of the City are provided sanitary sewer service as shown by
Figure 22. Approximately two hundred units were not served by
the City's system as reported in the 1990 Census. An area of the
City shown on Figure 22 receives sanitary sewer service from the
City of Pearland. If the residentially developed properties north of
this area were connected to a sanitary sewer system, it is likely they
too would be served by Pearland.
The non-served areas are scattered over the community and most are
close to existing lines, or could be reached by line extensions if the
line gradient is feasible.
Future Improvements - There is one area proposed to receive
sanitary sewer trunk lines through the impact fee capital improve-
ment program. This area is the Bay Area Boulevard Area which

also coincides with capital projects for water.
• The Bay Area Boulevard Service Area is proposed to be served
by a sanitary trunk force main system. The single biggest
factor influencing the selection of a force main over a gravity
trunk line in the channel by-pass being proposed by Harris
County Flood Control District. The details of the proposed
improvements are identified in the study for that area due out
in the Summer of 1998. �
Other projects will be financed by funds from sources other than
impact fees. These projects are designed to take service into
previously unserved areas.
The utility planning performed for the City has been designed to
match water and sewer services against growth in those areas not
heretofore served. Through the collection of impact fees over a
period of time as these areas develop, the capital costs and some
associated costs will be recovered whereby new development will
have paid for their lines. Other costs for improvement needed such
as extension of sewer services to developed properties will require
other funding sources to make these improvements.
SUMMARY Recent improvements and future plans for improvements to the
Blackhawk Wastewater Treatment Facility and current supplies of
water will allow the City adequate utility infrastructure and
availability through its expected built out capacity of a 48-50,000
. total population. Any increase beyond that point would probably
require increased capacity in wastewater treatment and increased
purchases of water supplies to accommodate that increase in
� population. _
