BACKGROUND
On January 14, 2025, the City Council approved plans (Attachment A) and specifications for the Citywide Sewer Improvements and granted authority to advertise for construction bids.
On March 11, 2025, the City Council awarded a construction contract in the amount of $649,325 to Torres Sanitation Systems Construction. Work commenced on April 14, 2025, and was completed on September 8, 2025.
ANALYSIS
The sanitary sewer improvements included: the removal and replacement of short damaged sections of sewer main at 50 spot locations throughout the City; installation of additional sewer manholes to enhance sewer main accessibility in hard to reach areas; and replacement of longer sections of old deteriorated cast iron and vitrified clay pipe with new vitrified clay pipe at 5 locations within the project limits to help improve sanitary sewer collection efficiency in these areas.
During the course of the project, five change orders resulting in $222,700 of additional costs were approved for the removal and replacement of short damaged sections of sewer main at 8 additional spot locations, removal of concrete encasement and interfering stormwater infrastructure and installation of additional fittings and sewer main at various spot repair locations, adjusting sewer manholes to grade, replacement of sewer manhole frame and cover, placement of additional slurry backfill, and additional labor and materials necessary to complete the work.
The Citywide Sewer Improvements project has been completed in accordance with the approved plans and specifications, and staff recommends that the City Council accept the project as complete and authorize the Director of Public Works/City Engineer to file the Notice of Completion with the Los Angeles County Recorder’s Office.
