Dear Mr. Morgan:

Please find enclosed the field reports resulting from
television inspection and smoke testing in the city's sanitary
sewer collection system. A summary accompanies these reports.
The majority of problems found were either on private

We hope that the information herein is helpful in abating
infiltration and inflow in the City of Friendswood study area.
