Mesa Water District Celebrates Six Years of 100 Percent Local Groundwater Supply Reliability

COSTA MESA, Calif.; March 13, 2019 — Mesa Water District is celebrating the sixth anniversary of its Mesa Water Reliability Facility (MWRF), which allows Mesa Water® to serve its customers with 100 percent locally sourced groundwater supplies –– a unique achievement in Orange County.

Initially built in 2000, the MWRF was improved from 2010 to 2012 to boost its production capacity, and was recommissioned on March 13, 2013. The MWRF’s state-of-the-art treatment technology increased the facility’s water production by 50 percent over the prior treatment process. In addition, the improved MWRF is more energy efficient, with less greenhouse gas emissions and a lower carbon footprint.

“The MWRF is a keystone of our innovative water reliability program,” says Mesa Water Board President, Shawn Dewane. “We are proud to be the only Orange County water provider to serve 100 percent of our community’s water needs with local water.”

With a one-million gallon reservoir and two deep-water wells, the MWRF pumps water from about 1,000 feet underground. The MWRF water is soft, high-quality water that meets all drinking water standards, and arrives with an amber tint which comes from an ancient redwood forest that formerly flourished in the area. Using nanofiltration technology, the water is filtered to ensure it is clear at the tap for Mesa Water customers.

The MWRF also features water-wise gardens with drought-tolerant plants, along with a small redwood forest as a tribute to the area’s past and the ancient-amber aquifer tinted by redwood remnants found deep in the lower groundwater basin.

Mesa Water is committed to the perpetual investment in, and proactive maintenance of, its water system, including the MWRF, which pumps, treats, and delivers around 1.4 billion gallons of quality drinking water annually to homes and businesses in its service area.
