Who We Are

The Water Research Foundation (WRF) is the leading research organization advancing the science of all water to meet the evolving needs of its subscribers and the water sector. WRF is a 501(c)(3) nonprofit, educational organization that funds, manages, and publishes research on the technology, operation, and management of drinking water, wastewater, reuse, and stormwater systems—all in pursuit of ensuring water quality and improving water services to the public.

WRF was formed in 2018 through the integration of three highly respected research collaboratives: WateReuse Research Foundation, Water Environment Research Foundation, and Water Research Foundation. Separately, these organizations focused on research to support varied segments of the water sector—water reuse, wastewater and stormwater, and drinking water, respectively. Now a One Water organization, WRF delivers the research programming the sector needs to address the most pressing water issues holistically.
