6. Discussion and Background
The City’s Sanitary Sewer Management Plan requires routine cleaning and video inspection of the City’s approximately 312 miles of sewer line to mitigate sewer overflows and maintain compliance with State Water Resource Control Board (SWRCB) Order No. 2006-0003-DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer System, and its Monitoring and Reporting Program (MRP) amendment WQ 2013-0058-EXEC.
Additionally, data collected from video inspections is used to identify infrastructure deficiencies and support planning for the Capital Improvement Program.
In June 2022, Tunnelworks Services, Inc. was awarded a competitively bid contract for sewer line cleaning, video inspection, and emergency response. The contract, identified as AGR-7380, had an initial three-year term valued at $1,134,117, with provisions for two one-year extensions, each worth $378,039. The initial term expired on June 30, 2025. On June 24, 2025, the City Council approved the first extension. Staff recommends approval of the second and final optional extension.
In June 2023, the contract was amended to increase its capacity by $29,940 to fund additional costs associated with sewer line cleaning and inspection. This increase brought the initial agreement amount to $1,164,057. The second amendment, which will expire June 30, 2026, increased the contract total to $1,542,096. The third and final amendment will increase the contract total to $1,920,135.
