Background:
California Water Code Sections 10610-10656 and 10608 requires that all urban water suppliers delivering over 3,000 acre-feet of potable water per year, or having more than 3,000 urban connections submit an Urban Water Management Plan (“UWMP”) once every five years. The City of Manteca’s (“City”) potable water supply is comprised of approximately 60% surface water, provided by South San Joaquin Irrigation District (SSJID), and 40% groundwater provided by City wells. The City currently has over 29,000 water service connections and in 2024 the City delivered over 6,000 acre-feet of groundwater. The surface water provided by SSJID is required to be included in their UWMP. The City is required to update and submit its 2025 UWMP to the California Department of Water Resources by July 1, 2026.
The plan must assess current and projected water demands and supplies, identify conservation measures, evaluate water supply reliability under varying hydrologic conditions, and ensures the City remains in compliance with state legislation, including Senate Bill X7-7 the Water Conservation Act of 2009, which required a 20% per capita water use reduction, and more recent requirements under Assembly Bill 1668 and Senate Bill 606 that establish long-term water use efficiency objectives and annual water supply assessments.
Failure to complete the UWMP would disqualify the City from State grants earmarked for drought response, recycled water, and infrastructure improvements.
On April 22, 2025, staff released a Request for Proposal (RFP) for preparation of the 2025 Urban Water Management Plan on the City’s Website.
Responses to all received questions were published on the City’s website on April 29, 2025. The RFP closed on May 13, 2025.
The City established an evaluation committee consisting of staff to evaluate and rank all the received proposals based on the advertised criteria. Based on the proposals received the evaluation committee concluded that West Yost is the most responsible, responsive, and qualified firm, and best meets the specific goals of the Project.
Fiscal Impact:
Funds have been appropriated in the Fiscal Year 2025-26 budget in the Water O&M Fund
(Fund 680) for the 2025 Urban Water Management Plan (FY26 ENG Outlay 26101).
