The treated water is discharged to the lake in the adjacent Balboa Park and then flows into the Los Angeles River, where it comprises the majority of the flow. The plant began operation in 1985 and processes 80 million US gallons (300,000 m 3 ) of waste a day, producing 26 million US gallons (98,000 m 3 ) of recycled water.
The treated water was applied to a sandy basin, where it was further treated by natural means and percolated down into the groundwater, which was in turn pumped back up for use as drinking water. In 1965, San Diego County created man-made lakes using treated sewage for recreational activities, including swimming and fishing.
The main facility is a 54-million-US-gallon (200,000 m 3) per day treatment plant in residential Martinez, California and it provides service to approx 462,000 residents. [1] It operates and maintains 1,500 miles (2,400 km) of sewer lines out of its second location in Walnut Creek, California. It is a California Energy Commission Showcase Plant.
Combined sewer outflow into the Anacostia River in Washington, D.C. Ratcliff Beach CSO discharges into the River Thames in London [7]. These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.
