2025 WateReuse California Annual Conference
September 21-23, 2025
Town and Country Resort



Our 2025 conference broke records and reimagined the possibilities for reuse in California.
More than 1,000 WateReuse members and water professionals gathered in San Diego September 21-23 for the annual conference.
The conference consisted of three days of technical sessions, workshops, and panels, including a Star Trek themed “Voyage to Potable Reuse by 2050” panel featuring key California water officials. The panel focused on planning for the future of reuse in California, including identifying specific targets for scaling up reuse, wastewater monitoring and pathogen reduction, and engaging the public to advance direct potable reuse. “Although challenging, we can make a trip to 2040 and perhaps hit 128 million acre feet per year in California,” said Chair of the California State Water Resources Control Board E. Joaquin Esquivel when asked about future goals for California reuse.
Water industry veterans Richard Nagel and Marsi Steirer were honored with Presidents’ Awards for their contributions to advancing reuse, and the conference was rounded out by a performance of the Pure Water Revival band consisting of WateReuse members. Mark your calendars for the 2026 WateReuse California Conference, next September in San Francisco!
