Costa Mesa Improves Water Quality with Ozone and Nano Filtration

The Mesa Consolidated Water District (Mesa Water) inaugurated the start of construction for its Colored Water Treatment Facility (CWTF) improvements project.

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. In planning since the 1980s, the CWTF went on-line in 2000 to tap into this water source using ozone to remove the color. The Facility is being improved with the installation of nano filtration membrane technology, and will return to service by mid-2012.

When completed in mid-2012, the CWTF will provide 50% more high quality soft water than the previous technology while using less energy. It will also protect the clear reserves by keeping colored water from migrating into the clear water zone.

Mesa Consolidated Water District (Mesa Water) provides water service to more than 110,000 customers in an 18-square-mile area.
