Southern California, USA – Planned IPR & DPR program, online in 2032, will become one of the world’s largest, benefitting 19 million people in Southern California

The Metropolitan Water District of Southern California is a regional water agency that operates and maintains an expansive range of reservoirs, water treatment plants, hydroelectric facilities, large-diameter pipelines and tunnels and about 400 service connections. Metropolitan’s drinking water system allows for the distribution of water imported from hundreds of miles away to their 26 member agencies, that provide water for 19 million people across 5,200 square miles.

Metropolitan’s imported supplies from the Colorado River and Northern Sierras are facing major long-term challenges brought on by climate change. So Metropolitan, in partnership with the Los Angeles County Sanitation Districts, is investing in a major water reuse program — Pure Water Southern California. The program provides an opportunity to develop a local and sustainable water supply for the region with the objective of producing up to 150 million gallons (567 million litres) per day, or enough water to meet the daily needs of 1.5 million people. Purified recycled water would be used to replenish the region’s groundwater basins and serve a new supply into Metropolitan’s water treatment plants.

Research on the latest advancements in water reuse and testing of the program’s state-of-the-art purification process takes place at the Grace F. Napolitano Pure Water Southern California Innovation Center, which houses a demonstration facility and learning center. Tours of the Innovation Center are available to the public.

Pure Water Southern California is expected to be online in 2032 and would ensure communities have access to safe, reliable drinking water for generations to come.
