BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
In February 2020, the Water Utilities issued Bid 20-032 for rehabilitation of approximately 214 existing sanitary sewer service laterals by utilizing installation of cured-in-place pipe (CIPP). The bid also includes installation of approximately 411 Vac-A-Tee cleanouts. One hundred of the Vac-A-Tee cleanouts will be installed in Cress Creek to facilitate sewer lateral line grouting, which will reduce groundwater infiltration.
Lining and/or grouting service laterals has shown to be effective in reducing groundwater and rainfall related infiltration and inflow into the sanitary sewer system. Excessive infiltration and inflow into the sanitary sewer system take up system conveyance capacity which may cause sanitary sewer overflows and sanitary sewer basement backups.
