Water Supply


The City of Hemet Water Department relies on local groundwater as the only water supply source for customers in its 5.25 square mile service area. Groundwater is currently pumped from the Hemet Groundwater basin by nine City-owned wells.

The City has water exchange service connections with EMWD and LHMWD, which provides an opportunity for water exchanges during emergency situations.


Fresh water supplies are often limited, whether by availability or a system's capacity to supply and treat water. Southern California typically faces challenges in meeting the summer demand, especially in times of drought, and Hemet is no different. As the population continues to grow, demand for water stresses our already limited water supplies. It is in our best interest as a community to engage in and promote clean water protection and conservation practices.

California DROUGHT—With California facing one of the most severe droughts on record, Governor Brown declared a drought State of Emergency in January 2014 and directed state officials to take all necessary actions to prepare for water shortages.

Urban Water Management Plans are prepared by California's urban water suppliers to support their long-term resource planning and ensure adequate water supplies are available to meet existing and future water demands. The CITY OF HEMET 2020 URBAN WATER MANAGEMENT PLAN was adopted by the Hemet city Council on July 2021.


The stakeholders in the Hemet/San Jacinto Groundwater Management Area have developed the Hemet/San Jacinto Water Management Plan to provide a foundation that guides and supports responsible water management in the future. The local stakeholders involved in the Plan include Eastern Municipal Water District (EMWD), Lake Hemet Municipal Water District (LHMWD), City of Hemet, City of San Jacinto, and Private Water Producers.
