Celebrating 30 Years of Recycled Water Innovation

SoFi Stadium, The Bolt (LA Chargers Training Facility), Intuit Dome and Top Golf in El Segundo are examples of customers that use recycled water produced by West Basin Municipal Water District! In fact, hundreds of South Bay businesses rely on West Basin’s recycled water for uses like landscape irrigation, toilet flushing, cooling towers and more. The District is honored to celebrate such a significant benchmark and is grateful to the sustainable vision and commitment of its recycled water customers who make this major achievement possible.

This water is distributed through more than 100 miles of recycled water pipeline serving nearly 600 recycled water connections. Together, these facilities make up the largest water recycling system of its kind in the U.S. serving as the only treatment system in the world that produces five types of recycled water tailored to the needs of municipal, commercial and industrial customers.

Using recycled water instead of drinking water for industrial and commercial applications helps to conserve drinking water for local communities. In the past 30 years the District has conserved enough drinking water to provide for 9.8 million people for one year. The recycled water program also reduces the amount of treated sewer water from the City of Los Angeles’ Hyperion Treatment Plant that enters Santa Monica Bay. Advanced treated disinfected recycled water is also injected into the groundwater basin as a barrier against seawater intrusion to protect our local underground drinking water supply.

We look forward to continuing this legacy and lasting impact for the next 30 years and beyond.  Celebrate this industry milestone with us and explore the 30 years of water recycling history and technology by joining a free water recycling facility public tour.

2025 marks the 30th Anniversary of the West Basin recycled water program, a monumental moment in the District's history. Since 1995, the West Basin has produced more than 265 billion gallons of recycled water - enough to fill about 813,225 football fields to one foot deep. Together with our recycled water customers, we celebrate the District's commitment, partnerships and contributions to creating and sustaining a resilient future for our water supply in Southern California.
