August 24-26, 2026 | San Francisco

Registration is now open for WateReuse California’s Annual Conference, taking place in San Francisco! Hear from the leading practitioners of water reuse in California, learn about San Francisco’s leadership on onsite water recycling, and meet colleagues new and old in a fun and focused setting. The early bird rate is open until May 29. 

The WateReuse community mourns the loss of Dr. James Crook, Ph.D., P.E., who passed away on March 24, 2026. For nearly a half century, Dr. Crook was a central figure in advancing water recycling as an environmental engineering consultant and in state government serving the public and private sectors in the United States and abroad. He spent 15 years directing the California Department of Public Health’s water reuse program, during which time he developed California’s first comprehensive water reuse criteria. He served as a member of the WateReuse Association Board of Directors and on the Research Advisory Committee for the former WateReuse Research Foundation, along with leadership roles in several other water organizations throughout his career. 

The WateReuse Association and WateReuse California welcome Klir! Klir is a Software-as-a-Service platform which centralizes, streamlines, and automates programs for drinking water and wastewater systems, driving operational efficiency. Klir digitally transforms compliance programs and operational data, providing proactive insights into water quality and system performance. 

Last week, Daytona Beach city commissioners advanced a ballot question asking voters to approve a ban on potable reuse. Florida passed regulations for potable reuse in 2025, and in 2021 enacted a law requiring that municipal water systems stop nonbeneficial discharges of reclaimed water to surface water bodies by 2032. “A local ordinance that prohibits potable reuse or the use of highly treated reclaimed water for aquifer replenishment would significantly limit the range of available solutions that utilities may rely upon to meet the state’s requirements,” wrote WateReuse Florida President Kerry Kates in a letter to Daytona Beach. Daytona Beach residents will vote on the charter amendment in November. 

WateReuse Texas is accepting proposals for the 2026 WateReuse Texas Conference, taking place September 15-17, 2026 in San Antonio.

Accepted formats include a 30-minute presentation or a 60-minute presentation or panel.

Submit by Friday, April 17 to take the podium at Texas’ most comprehensive water reuse event.  

This month, Waco received a $1 million federal award for the Flat Creek Water Reuse Project, which aims to create a non-potable reuse system for industrial and commercial end users. Waco Mayor Jim Holmes shared the project’s aim to help sustain economic growth in the city: “As we’ve seen a lot of great economic development in the city over the last six, eight years — 4,000 new jobs, $4 billion in new investment, 40 new companies coming to town — we have to be thoughtful about our water resources,” he told KWTX. The initial funding will be used for phase 1 of the estimated $57 million project, beginning with infrastructure upgrades within the city’s wastewater treatment plant.
