Mesa Water District Breaks Ground on its Colored Water Treatment Facility Imporvements Project

Project Allows Mesa Water to Achieve Its Goal Of 100 Percent Local Reliability

Costa Mesa, Calif. ; May 4, 2011 – The Mesa Water District (Mesa Water) Board of Directors inaugurated the start of construction for its Colored Water Treatment Facility improvements project with a ceremonial groundbreaking on April 19, 2011.

“The Colored Water Treatment Facility produces delicious, soft, high-quality water. The Facility expansion will allow Mesa Water to achieve our goal of being able to produce 100 percent of our water from local sources,” said the District’s Board President, Fred R. Bockmiller, Jr., P.E.

When completed in mid-2012, Mesa Water’s improved Colored Water Treatment Facility will provide the following benefits;

  • High-quality soft water;
  • 50 percent more water than the previous technology while using less energy;
  • Groundwater clean-up by keeping colored water from migrating into the clear water zone; and,
  • 100% local water reliability.

Mesa Water closed its Colored Water Treatment Facility for improvements on December 30, 2010. The contractor completed the demolition phase in mid-April 2011, and the expanded Facility is scheduled to return to service by mid-2012, just in time for peak summer demands.

About the Colored Water Treatment Facility

Mesa Water sits above a portion of Orange County’s groundwater basin that includes a supply of amber-colored water hundreds of feet below the clear-water reserves. Of very high quality and safe to drink, the colored water has a slight amber tint resulting from the buried ancient redwood forests that grew in the area. In planning since the 1980s, the District’s Colored Water Treatment Facility went online in 2000 to tap into this water source, using a revolutionary ozone filtration process to remove the color from the water. Before its final shut down in December 2010, the Facility produced 15 billion gallons of water. The Facility is being improved with the installation of nanofiltration membrane technology, and will return to service by mid-2012.
