Urban Water Management Plan (UWMP)

An Urban Water Management Plan (UWMP) helps water suppliers evaluate the availability and reliability of their water supplies and assess current and future water demands. The purpose of the plan is to ensure that communities continue to receive reliable water service under a variety of conditions, including droughts, changing climate patterns, and population growth.

Long-term water supply planning is especially important in California, where climate change is affecting rainfall and snowpack patterns, and continued development throughout the state is increasing the demand for reliable water supplies.

Under the California Urban Water Management Planning Act, larger water suppliers that serve more than 3,000 customer connections or supply more than 3,000 acre-feet of water annually are required to prepare and update a UWMP every five years. Each plan evaluates water supply and demand conditions over a 20-year planning horizon, ensuring that water providers continue to plan for the future and maintain reliable service.

The Stanislaus Regional Water Authority (SRWA) and the City of Turlock are required to prepare a UWMP because they provide water service to more than 3,000 connections within their service areas.

SRWA supplies treated surface water to its two wholesale customers, the California cities of Turlock and Ceres. This Joint UWMP has been prepared collaboratively by SRWA and the City of Turlock. The City of Ceres has prepared its own 2025 UWMP separately; however, the plans were coordinated to ensure consistency and accuracy between the agencies.

This Executive Summary serves as the Lay Description of the SRWA and City of Turlock Joint Urban Water Management Plan, as required by California Water Code Section 10630.5.

2020 Urban Water Management Plan

An Urban Water Management Plan (UWMP) helps water suppliers assess the availability and reliability of their water supplies and current and projected water use to help ensure reliable water service under different conditions. This water supply planning is especially critical for California currently, as climate change is resulting in changes in rainfall and snowfall which impact water supply availability and development is occurring throughout the State resulting in increased needs for reliable water supplies. The Urban Water Management Planning Act (Act) requires larger water suppliers that provide water to urban users (whether directly or indirectly) to develop UWMPs every five years. UWMPs evaluate conditions for the next 20 years, so these regular updates ensure continued long-term planning. Since the City of Turlock (City) provides water service directly to more than 3,000 connections in its service area, it is required to prepare a UWMP. This Executive Summary serves as a Lay Description of the City's UWMP, as required by California Water Code §10630.5.
