New Requirements for 2025 UWMP
Topic Summary
Making Conservation
a California Way of
Life
Effective January 1, 2025, this regulation sets annual "urban water use objectives" (UWUOs) for urban retail water suppliers. The water budgets are based on a supplier's specific factors, such as indoor and outdoor residential use, commercial and industrial irrigation, and water loss.
Water Loss Control Regulations for urban retail water suppliers to develop performance standards for minimizing water system leaks became effective on July 1, 2023.
Monthly Water
Conservation Reports
Since October 1, 2020, urban water suppliers have been required to submit monthly conservation reports to the SWRCB.
Prohibition on
Nonfunctional Turf
Irrigation
AB 1572, signed in October 2023, bans the use of potable water for irrigating "nonfunctional turf" in CII areas. The ban will be phased between 2027 and 2029.

Supply and Demand Assessment
• Average Water Year – Supply > Demand
• Single-Dry Year – Supply > Demand
• Multiple-Dry Years – Supply > Demand
• Drought Risk Assessment – Supply > Demand
• The City anticipates it can supply all of its water demands with groundwater from the Red Bluff Subbasin through the
planning horizon (2050) for all water year scenarios.
