West Basin declares record year in recycled water output

West Basin Municipal Water District in California has declared fiscal year 2013-14 a record 12 months in recycled water production at its Edward C Little Water Recycling Facility. The plant produced 60,000 Ml of recycled water in the period.

Earlier this year, West Basin – which serves Culver City – reached another milestone of 750,000 Ml of recycled water produced at the Edward C Little facility, which has been operating since 1995. The milestones in water recycling were pushed along by the facility’s fourth expansion, completed in 2013, to up its capacity to treat wastewater from 225 Ml/d to 310 Ml/d.

None of the wastewater treated at the facility is released into the ocean. “West Basin has a state-of-the-art water recycling program and is the only one in the world that produces five types of ‘designer’ waters to meet our customers’ needs,” said West Basin board president, Donald L Dear.

The five types of water produced by the plant are: irrigation water (tertiary disinfected); cooling tower water (nitrified); low-pressure boiler feed water (single-pass reverse osmosis); high-pressure boiler feed water (double-pass reverse osmosis); and indirect drinking water (microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide disinfection).
