Denton Creek Regional Wastewater System

IMG_2341 - Copy - CopyThe Denton Creek Regional Wastewater System, an 11.5 MGD facility, provides regional wastewater transportation* and treatment services to an area of approximately 170 square miles, immediately west of Grapevine Lake in Denton and Tarrant Counties. The treatment plant is located adjacent to and has one discharge outfall to the Cade Branch of Denton Creek. The plant has a second discharge outfall to Whites Branch Creek, located in the Town of Flower Mound. Both creeks enter Grapevine Lake. The plant is located in the city of Roanoke on a plant site of approximately 48 acres and serves all or part of 10 cities and two municipal districts.

The system is designed for advanced activated sludge with nitrification and denitrification processes for phosphorus removal, preceded by preliminary treatment and followed by advanced tertiary filtration and ultraviolet (UV) disinfection.

IMG_2316A 5.0 million-gallon detention basin was constructed as a sequencing batch reactor to treat additional loadings from the Texas Motor Speedway racetrack. Waste solids from both the conventional treatment system and the detention basin are dewatered through two centrifuge units and disposed of off-site in a municipal landfill.

DCRWS' excellent history of compliance with its National Pollution Discharge Elimination System permit has been rewarded by the National Association of Clean Water Agencies. 

*Transportation denotes the movement of wastewater through pipes from customer cities to the treatment plant.
