Regional Recycled Water Advanced Purification Center
Award
Water/Wastewater Treatment Project
Description
The Regional Recycled Water Advanced Purification Center is a 500,000 gallon-per-day demonstration facility designed to test an innovative advanced water treatment process train for potable reuse. The project is a partnership between The Metropolitan Water District of Southern California and the Sanitation Districts of Los Angeles County (Sanitation Districts). It will demonstrate an effective purification process for the Regional Recycled Water Program, a water reuse effort that could eventually produce up to 150 million gallons of purified water and a new reliable water supply for Southern California.
The Regional Recycled Water Advanced Purification Center began operations in October 2019 and is located at the Sanitation Districts’ Joint Water Pollution Control Plant (JWPCP) in Carson. The facility purifies treated wastewater from the JWPCP using an innovative three-step purification process consisting of membrane bioreactors , reverse osmosis and an ultraviolet light/advanced oxidation process. Key goals of the demonstration facility include testing this innovative purification process, ensuring it produces water safe for potable reuse, and obtaining regulatory approval of the process.
Metropolitan and the Sanitation Districts are working with the State Water Resources Control Board’s Division of Drinking Water and the Los Angeles and Orange County Regional Water Quality Control Boards for regulatory approval. Once water quality testing demonstrates that the resulting purified water meets all requirements for replenishing groundwater basins, the process would be approved by regulators and may be used in water reuse projects throughout California.
The Regional Recycled Water Advanced Purification Center allows Metropolitan and the Sanitation Districts to optimize operations, identify costs, gather operational data, and develop design parameters needed for a future full-scale facility. Furthermore, the facility is used to showcase the project to the public and gain support for this potential new source of water for Southern California.
