The West Harris County Regional Water Authority (WHCRWA) was created by the Texas Legislature to identify and secure a long-term supply of quality drinking water at the lowest responsible cost, to promote water conservation, and to facilitate compliance with groundwater reduction strategies and mandates. In 2003, the WHCRWA successfully negotiated a long-term water supply contract with the City of Houston, and design and construction of the necessary transmission lines and facilities began. In 2010, WHCRWA met the first of the Subsidence District’s groundwater reduction mandates by converting to more than 30 percent surface (or alternate) water. WHCRWA also successfully met the 60 percent conversion requirement in 2025. The next groundwater reduction requirement is 80 percent by 2035.

The WHCRWA is not a MUD and does not control any MUD operations, including delivering water to homes and businesses, sewer services, billing, or other retail services. The WHCRWA is a wholesale water provider and does not provide retail water services. If you have a question about your retail water or sewer service, please contact your MUD or local water provider. You can use WHCRWA’s Find Your Water Provider tool to locate your provider and contact information.
