SUBJECT: APPROVAL OF CONSTRUCTION CONTRACT FOR CITYWIDE SEWER IMPROVEMENTS, CAPITAL IMPROVEMENT PROJECT (CIP) NO. 24-24
EXECUTIVE SUMMARY
The City Council will consider awarding a contract to Torres Sanitation Systems Construction in the amount of $649,325 for the construction of Citywide Sewer Improvements, CIP No. 24-
24. The proposed sewer improvements, which would occur on various streets throughout the northwest, northeast, and southwest quadrants of the City, are necessary to ensure reliable sanitary sewer service in these areas and include replacement of damaged sections of sewer main and installation of additional sewer manholes for maintenance accessibility.
RECOMMENDATION
That the City Council:
1. Award a contract to Torres Sanitation Systems Construction in the amount of $649,325 for the construction of Citywide Sewer Improvements, CIP No. 24-24; and
2. Authorize the City Manager, or his designee, to execute any change orders or additional scope of work for this project deemed necessary or desirable up to the approved project budget of $1,400,000.
BACKGROUND
As part of the City’s annual sanitary sewer maintenance program, a number of the City’s sewer mains are analyzed via sewer flushing and video assessments, which identifies areas in need of repair to ensure continued efficiencies of the sanitary sewer collection system.
Sewer mains along various streets throughout the northwest, northeast, and southwest quadrants of the City need repair and rehabilitation to ensure that the City is able to continue to use this infrastructure to provide reliable sewer service to the community. The project limits are shown on the project location map included as Attachment A.
ANALYSIS
On January 14, 2025, the City Council approved plans and specifications and granted authority to advertise the subject project for bids (Attachment B). A copy of the project

specifications is available for review in the Public Works Department. The proposed sanitary sewer improvements include: the removal and replacement of short damaged sections of sewer main at 42 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.
The project was posted on Planet Bids on January 23, 2025, advertised in the Downey Patriot on January 23 and 30, 2025, and published in various trade publications. On February 12, 2025, the City received eleven bids electronically through Planet Bids ranging from $649,325 to $1,547,050. The bid results were as follows:
