The Texas Water Development Board (TWDB) recently approved financial assistance to the Trinity River Authority-Ten Mile Creek Regional Wastewater System in the amount of $50 million from the Clean Water State Revolving Fund to finance wastewater system improvements, utilizing the pre-design funding option.

The Trinity River Authority’s Ten Mile Creek Regional Wastewater System lies south of the city of Dallas in Dallas and Ellis counties and serves a population of about 130,000 within the contracting parties of Cedar Hill, Duncanville, Desoto, Lancaster and Ferris. Parts of Cedar Hill are also serviced by the authority’s Red Oak and the Central regional systems, while parts of Desoto and Lancaster are serviced by the authority’s Red Oak Regional System. In addition, parts of Duncanville are serviced by the authority’s Central Regional System.

The TMCRWS is made up of a regional interceptor network and an activated sludge wastewater treatment plant currently permitted to treat a monthly average of 24.0 million gallons per day. The authority will utilize the loan proceeds for the construction of improvements to the Ten Mile Creek Regional Wastewater Treatment Plant and about 30,000 linear feet of 18-inch through 72-inch sanitary sewer line.

The TWDB is the state agency charged with collecting and disseminating water-related data, assisting with regional planning and preparing the State Water Plan for the development of the state’s water resources, and administering cost-effective financial programs for the construction of water supply, wastewater treatment, flood control and agricultural water conservation projects.
