In a decisive move to address escalating water challenges in the Southwest, the U.S. Bureau of Reclamation has awarded $26.2 million to Pure Water Southern California, a water recycling effort led by the Metropolitan Water District (MWD) and the Los Angeles County Sanitation Districts.
This funding builds on the $99.2 million grant awarded earlier this year under the Department of the Interior’s Large-Scale Water Recycling Program, backed by the Bipartisan Infrastructure Law.
“Climate change is stressing water supplies across the Southwest. We’re already seeing hotter, drier conditions, and it is only going to get more challenging in the decades ahead. So we’ve got to make big investments in reliable, sustainable water supplies. We’re thrilled that our federal partners are supporting these efforts,” MWD Interim General Manager Deven Upadhyay said.
Pure Water Southern California is designed to take treated wastewater—currently discharged into the ocean—and purify it through advanced multi-stage treatment. The result? High-quality drinking water.
Once fully operational, the project could produce 150 million gallons of water per day, meeting the needs of 1.5 million residents.
A Regional Blueprint for Resilience
“This is a huge project – potentially one of the largest water recycling projects in the world – that will benefit not only the 19 million people of Southern California, but the entire state and Southwest,” MWD board Chair Adán Ortega, Jr., said. “It will help lower demands on our imported water sources from the Colorado River and on the Northern Sierra. And it will help keep the economic engine of Southern California running, regardless of the future drought conditions we may face.”
The $26.2-million grant will fund critical early steps, including planning, design, and essential infrastructure upgrades. An Environmental Impact Report is underway, with public review anticipated in 2025. If all goes to plan, the project will deliver its first recycled water by 2033, reshaping water management for the region.
This grant is part of the Department of the Interior’s $450 million Large-Scale Water Recycling Program, aimed at addressing the water crisis in the West. To date, the program has allocated more than $300 million to projects tackling water scarcity, including initiatives led by the Los Angeles Department of Water and Power, Ventura, the Inland Empire Utilities Agency, and Utah’s Washington County Water Conservation District.
By turning treated wastewater into a sustainable, drought-resilient resource, this long-term, broad-range public investment signals a shift in how Southern California and the broader region secure their water future.
As the Southwest contends with shrinking reservoirs and intensifying droughts, projects like Pure Water Southern California provide a blueprint for resilience. With federal support and bold regional leadership, the path forward is clearer—and significantly brighter.
