ITEM SUMMARY:
Since January 2022, staff has been reviewing the City’s Sanitary Sewer Evaluation Survey (SSES) and Repair
Program for efficiency. On June 2, 2022, staff had a lengthy discussion with the Infrastructure Committee regarding
the SSES and Repair Program. Staff was directed to complete an SSES study in the center and southeast portion
of the City. Due to the volume of repairs identified in previous SSES studies, once the study is completed, the focus
will shift solely to the repairs until all outstanding items have been addressed. This will be the last evaluation
program conducted for the foreseeable future.
The City has conducted SSES studies in 2010, 2011, 2013, 2014, 2016, and 2018. The primary purpose of these
studies is to find defects in the sanitary sewer collection system. The defects are found via dye testing, smoke
testing, sewer televising, and manhole inspections. As part of these studies, accurate location of City infrastructure
such as manhole locations is also captured in a Geographic Information System (GIS) database.
The 2022-2023 SSES program is a continuation of the previous studies. This survey work will encompass the
areas of the City that have not been inspected during the programs from 2010-2018. The remaining area is roughly
Harrison Street south to Dayton Avenue and Lyman Avenue east to Route 59. A location map is attached for
reference. The study area encompasses roughly 80,000 lineal feet of sanitary sewer and approximately 326
sanitary manholes. The data collected will then be used to finalize a cost effective sanitary sewer repair program
for implementation in future years. Due to their knowledge and familiarity with City’s sanitary sewer system as well
as successfully performing previous SSES studies, after direction from the Infrastructure Committee, City staff
approached RJN Group, Inc. (RUN) to request a cost proposal for the 2022-2023 SSES program.
RJN submitted the initial proposal in the amount of $246,783.26. After successful negotiations, RJN has submitted
a revised not to exceed proposal in the amount of $232,588.36. RJN’s scope of work will include manhole mapping
and inspections, smoke testing, wet weather investigations, and dye testing of the sanitary collection system
tributary to the locations noted above. Please note unlike our previous studies, in an effort to reduce costs, City
staff will be performing the sewer televising with City equipment. RJN’s scope of work includes analyzing our
televised data and properly coding the defects using an artificial intelligence software. The study will begin with
manhole inspections in September 2022 and final report is expected by October 2023.
In FY2022 Sewer Fund, Sewer Main Repairs (05-34-43-4410), $700,000 has been budgeted for the 2022-2023
SSES program.
