Document Description
Pure Water is a proposed partnership between The Metropolitan Water District of Southern California (Metropolitan) and the Los Angeles County Sanitation Districts (Sanitation Districts) to beneficially reuse cleaned wastewater that currently is being discharged to the Pacific Ocean from the Sanitation Districts' A.K. Warren Water Resource Facility (Warren Facility) in the City of Carson. Pure Water would produce a new sustainable local water supply by harvesting one of the region's largest untapped sources of cleaned wastewater to produce nearly 155,000 acre-feet per year of highly purified water. A new Advanced Water Purification Facility would be constructed on currently undeveloped property within and adjacent to the Warren Facility. The purified water would then be transported and distributed via new conveyance facilities as far north as the City of Azusa and as far east as the City of La Verne. The purified water would be used primarily to recharge the West Coast, Central, and Main San Gabriel groundwater basins through spreading facilities and injection wells and to augment water supplies at existing water treatment plants owned and operated by Metropolitan within its service area.
