Water Supply
Imported Water
The majority of EMWD’s potable (drinking) water demand is supplied by imported water from The Metropolitan Water District of Southern California through its Colorado River Aqueduct and its connections to the State Water Project.
Groundwater
Approximately 20 percent of EMWD’s potable (drinking) water demand is supplied by EMWD groundwater wells. The majority of the groundwater produced by EMWD comes from its wells in the Hemet and San Jacinto area. Some of these wells have limited production as a result of the Fruitvale Judgment and Decree. EMWD also has wells in the Moreno Valley, Perris Valley and Murrieta areas.
Sustainable Groundwater Management Act
The Groundwater Sustainability Plan Public Draft is ready for review (Program Documents)
The objective of SGMA is sustainable groundwater management in a manner that prevents significant and unreasonable impacts to groundwater basins in California. Under SGMA, each high and medium priority basin, as identified by the California Department of Water Resources (DWR), is required to have a Groundwater Sustainability Agency (GSA) that will be responsible for groundwater management and development of a Groundwater Sustainability Plan (GSP). EMWD Board of Directors is the GSA for the West San Jacinto Groundwater Basin and is responsible for development and implementation of a GSP.
