California regulators on Tuesday cleared the way for widespread use of advanced filtration and treatment facilities designed to convert sewage waste into pure drinking water that can be pumped ...
The regulations are expected to be approved Tuesday by the State Water Resources Control Board, enabling water suppliers to begin building advanced treatment plants that will turn wastewater into ...
The drinking water that the plant produces will be piped 10 miles northeast to L.A. County’s Hansen Spreading Grounds, where it will flow into basins and percolate into the groundwater aquifer ...
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.
Calls for a comprehensive statewide water management system (complementing the extensive, but primarily irrigation-based Central Valley Project) led to the creation of the California Department of Water Resources in 1956. The following year, the preliminary studies were compiled into the extensive California Water Plan, or Bulletin No. 3.
California's new rules would let — but not require — water agencies take wastewater, treat it, and then put it right back into the drinking water system. California would be just the second ...
Groundwater that is a subterranean stream is subject to the same water right permitting requirements as surface water. California has no statewide water right permit process for regulating the use of percolating groundwater. A subterranean stream meets the following four characteristics: (1) A subsurface channel must be present; (2) The channel ...
