CARSON, CA, Apr. 14, 2011 -- West Basin Municipal Water District's Edward C. Little Water Recycling Facility will be undergoing its fourth expansion since its original construction in 1995. The facility, located in El Segundo, is the only facility in the world that produces five different types of recycled sewer water.

The expansion, which will be conducted under a design-build team from Parsons, will help West Basin fulfill its goal to double recycled water production by the year 2020. The project will increase the facility's production from its current 30 million gallons per day (MGD) to 46 MGD.

The project will include expansion of microfiltration, reverse osmosis and ultraviolet advanced oxidation process facilities to supply an additional 5 MGD to the seawater barrier to prevent seawater intrusion and refill groundwater supplies.

A single pass reverse osmosis membrane water purification system at Chevron's El Segundo refinery will also be expanded to bring an additional 500,000 gallons a day to NRG Energy's El Segundo Power Plant.

Other work will include an ozone pre-treatment facility, irrigation water facilities (Title-22 high rate clarification unit), and various solids handling facilities will be added to the ECLWRF to improve water quality and efficiencies at the plant.
