Carrollton Ensuring State-of-the-Art Water Quality

Post Date:07/24/2019 2:38 PM

DWU-Elm-Fork-Upgrades-imageThe City of Carrollton and Dallas Water Utilities (DWU) are “superior” rated water systems, the highest rating assigned by the Texas Commission on Environmental Quality. In order to maintain its superior water rating and in an effort to continuously strive to be the best, DWU is making substantial investments at its water purification plants and these improvements will further enhance the water quality for Carrollton residents.

Upgrades at DWU’s Elm Fork Water Treatment Plant (WTP) will be implemented in phases over the next several years. The first stage will begin in early August and Carrollton residents are primed to benefit from the enhanced filtration system.

The installation is the result of a source-to-tap water quality study conducted by DWU. The study identified filtration process modifications and operational changes to improve the distribution quality.

Once the first stage conversion is complete at the Elm Fork WTP, implementation of system upgrades are scheduled to follow in 2024 with construction of a new filtration complex. According to DWU, water is tested 40,000 to 50,000 times every month throughout the entire water system. DWU has established water quality parameters and expects the numbers will continue to stay within the established ranges.

The City of Carrollton contracts with DWU for the community’s water supply. DWU utilizes surface water from seven sources and owns and operates three large water purification plants. DWU’s Elm Fork WTP itself processes 310-324 million gallons per day (MGD) and receives water from the Elm Fork of the Trinity River, Ray Roberts Lake, Lewisville Lake, and Lake Grapevine.
