2026 Annual Water Supply Demand Assessment

Proposals are being accepted by West Basin Municipal Water District (West Basin), a Municipal Water District, for 2026 Annual Water Supply Demand Assessment .

In 2018, the California Legislature enacted into law new requirements for urban water suppliers to increase drought resilience and to improve communication of water shortage response actions. Each urban water supplier is required to prepare an Annual Water Supply and Demand Assessment (Annual Assessment) and submit an Annual Water Shortage Assessment Report (Annual Shortage Report) to DWR on or before July 1, 2022, and every year thereafter.

Suppliers are responsible for providing a reliable supply of water for their customers, evaluating their water supply status on a regular basis and, in the case of anticipated water shortages, preparing mitigation actions.

West Basin Municipal Water District (West Basin) is a public agency that provides imported drinking water and recycled water to 9 retail agencies and nearly one million people in the coastal Los Angeles area. West Basin is a member agency of the Metropolitan Water District of Southern California. West Basin's mission is to provide a safe and reliable supply of high-quality water to its customers and communities with a commitment to water reliability, water quality, sound financial and resource management, customer service and environmental stewardship.
