Water Supply / Drought Status

While much of the state and western United States is experiencing prolonged dry and drought conditions, EMWD has proactively prepared for these cyclical periods through investments in a diverse water supply portfolio, successful management of its resources, and other programs to promote water use efficiency.


How We Save Water
We are in a serious drought. Stay WaterWise.

Logo - Stay Water Wise with outdoor efficiencyUsing water wisely is a way of life for Southern California residents.  The drought cycle comes second nature to us and we know that staying WaterWise doesn’t have to be a big and scary task.  It can be as simple as reducing irrigation timers by 2 minutes for every 10 minutes or switching standard sprinklers to rotating nozzles.  Whether you’re a homeowner or a renter, small changes like these add up to big savings in both gallons and dollars.  When we Stay WaterWise we fulfill our responsibility of helping California through the cycle of droughts.


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.



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 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.
