Western is embarking on a collaborative effort to develop resilient, reliable, and fiscally responsible Urban Water Management and Drought Contingency Plans that support our region’s long-term needs.

Urban Water Management Plan 2020

Water agencies in California that serve more than 3,000 customers or 3,000 acre-feet (AF) annually are required by California law to prepare an Urban Water 

Management Plan (UWMP or Plan) every five years. The Plan supports Western’s long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs. The Plan integrates local and regional land use planning, regional water supply, infrastructure, and demand management projects, as well as statewide issues of concern like climate change and regulatory requirements.

Water Shortage Contingency Plan 2022

Western’s Water Shortage Contingency Plan (WSCP)  documents Western’s plans to manage and mitigate an actual water shortage condition, should one occur because of drought or other impacts on water supplies. The WSCP incorporates the details described in Western’s retail Ordinance 394. Ordinance 394 establishes an updated retail customer water supply shortage contingency response program (Program). The Program establishes six water shortage stages, implements water supply shortage responses measures, regulates water consumptive within the District to conserve and protect the District’s water supplies, to reduce water consumed, and to prevent waste or reasonable use of water.  The Water Code also specifies the contents and procedures for Western’s adoption of the WSCP.

Drought Contingency Plan 2022

The United States Bureau of Reclamation (USBR) has developed a Drought Response Program to improve its ability to assist states, tribes and local governments to prepare for and address drought in advance of a crisis. This Drought Response Program supports a proactive approach to drought by providing assistance to water managers to develop and update comprehensive drought plans. 

Western received grant funds to develop a Drought Contingency Plan (DCP). Western’s Board of Directors adopted the plan on July 20, 2022. USBR approved the final plan in September 2022.
