About the WateReuse Association

The WateReuse Association is a nonprofit organization whose mission is to advance the beneficial and efficient uses of high-quality, locally produced, sustainable water sources for the betterment of society and the environment through advocacy, education and outreach, research, and membership. Across the United States and the world, communities are facing water supply challenges due to increasing demand, drought, depletion and contamination of groundwater, and dependence on a single source of supply.


The WateReuse Association of California was formed in December 1990 when the Association of Water Reclamation Agencies (AWRA), a policy & regulatory organization, merged with the California Association of Reclamation Entities of Water (CAREW), a technical organization. In 1993, the Association formed an affiliate organization — the WateReuse Foundation — whose purpose was to conduct applied research on alternative water supplies such as the reuse of reclaimed water.

 After a decade as a state Association, the Board of Directors decided that alternative water supply needs stretched far beyond the borders of California.The organization was reincorporated as the WateReuse Association in April 2000. The Board hired its first full-time executive director on August 1, 2000, and established an office in the Washington, DC area. Currently a staff of full-time professionals is employed in its Alexandria, VA headquarters office.

The WateReuse Association is a trade association and is recognized as a tax-exempt organization under Section 501(c)6 of the Internal Revenue Code. As a “501(c)6 organization,” the Association is allowed to engage in advocacy (i.e., lobbying) at both the national and state levels of government.

By contrast, the Association’s affiliate organization — the WateReuse Foundation — is recognized as a tax-exempt organization under Section 501(c)3 of the Internal Revenue Code. As a “501(c)3 organization,” the Foundation is an “educational and charitable” organization and is, therefore, prohibited from expending a disproportionate amount of its revenues on lobbying.


Water reuse and desalination will continue to grow in the United States and around the world as they become increasingly recognized as reliable, safe alternative sources of supply. WateReuse has experienced and diverse members in the U.S. and abroad. In addition to local utilities, the membership includes federal and state agencies, health officials, consultants, and prominent researchers from the academic community.

WateReuse members employ proven and advanced treatment processes and rigorous monitoring regimes to create reliably high-quality water for a wide variety of uses from treated municipal and industrial effluents, stormwater, agricultural drainage, and sources with high salinity such as seawater and brackish water.
