Water Reuse as a Water Management Strategy for Small Communities in Texas, Saqib Shirazi and Jorge Arroyo, Innovative Water Technologies, TWDB, April 2010, (96.6 KB).

The 2007 State Water Plan of Texas (TWDB, 2007) projects that water reuse will account for 14 percent of the state's new water supply by the year 2060. The majority of this volume corresponds to water management strategies to serve large urban areas in water planning regions C, H, and K. However, the growing need for new water supplies and greater awareness of the benefits of water reuse will eventually lead smaller communities in the state to also consider water reuse management strategies. The U.S. Environmental Protection Agency defines a small community as one which has a population less than 10,000 and a total wastewater flow of less than 1 million gallons per day. This report examines water reuse issues such as regulations, water rights, and technology as an initial step to identify key challenges that smaller communities may face in implementing water reuse strategies.
