Eastern Municipal Water District (EMWD) opened its third groundwater desalination facility Friday.
According to the District, The Perris II Desalination Facility will provide water for more than 15,000 households each year through its reverse osmosis treatment process. The facility is located in Menifee, adjacent to the existing Menifee I and Perris I desalters.
“This is a historic day for EMWD and for the residents we serve,” EMWD Board President Phil Paule said. “As we continue to face water supply challenges throughout California, this facility will further ensure that our area is prepared to meet the needs of our customers through investments in local water supply sources.”
The Perris II Desalter will treat approximately 5.4 million gallons of water per day. EMWD’s groundwater desalination program will collectively treat approximately 14 million gallons per day – enough for more than 30,000 households annually.
The Perris II Desalter was funded in part by approximately $22.5 million in grant funding from the State Water Resources Control Board (State Board) through Proposition 1, the 2014 voter-approved water bond.
Additional funding and in-kind support was provided by the United States Army Corps of Engineers, which provided $10.8 million toward the construction of wells to support the new facility; the California Department of Water Resources; United States Bureau of Reclamation; Santa Ana Watershed Project Authority; and The Metropolitan Water District of Southern California.
