Tarrant Regional Water District, Texas, USA – Planned Reservoir Augmentation, large wholesaler supplying around 2.5 million people in North Texas

The Tarrant Regional Water District is a large wholesale raw water provider to the western side of the Dallas/Fort Worth area, and a pioneer in using wetlands to clean water. Tarrant Regional Water District currently provides raw water to over 2.5 million people in 11 counties or more than 90 customers.

Tarrant Regional Water District’s future Marty Leonard Wetlands Water Reuse Project is another way it is extending its current resources to meet a rapidly growing population. The 3,000-acre Marty Leonard Wetland Water Reuse Project is currently under design and will be located on the east bank of the Trinity River near Cedar Creek Reservoir.

The Leonard Wetlands Project is scheduled to be operational by 2032 and is capable of treating Tarrant Regional Water District’s permitted 88,059 Acre-Feet per Year (78 million gallons per day or 297 million litres a day) of return flow with additional capacity to treat purchased return flows. It consists of a series of sedimentation ponds and man-made wetland cells that naturally filter highly treated recycled water diverted from the Trinity River, which is then put it back into Cedar Creek Reservoir for use as water supply.

In the critically dry summer months this wetland project has the ability to provide 176 million gallons (666 million litres) a day, almost doubling the supply of Cedar Creek Reservoir, helping the region cope with the severe drought conditions affecting the North Central Texas area. The Leonard Wetlands will also provide valuable wildlife habitat.

This project is in addition to TRWD’s current wetland facility, see the George Shannon Wetlands Water Reuse Project.
