Tarrant County Water Management District
Water Quality Project
The Tarrant County Water Management District (TCWMD) supplies about 60% of
the drinking water for the Dallas/Fort Worth area. An assessment of future
water needs determined that the TCWMD would exceed present water supply by
approximately 50% over the next 50 years. In the past, the TCWMD acquired
new lands and built upland reservoirs to be able to keep up with the water
demand of the growing Dallas/Fort Worth area.

This time, TCWMD decided to look at another solution commonly used to conserve
water in irrigation systems called tailwater recovery. The Trinity River flows
very close to two existing reservoirs that TCWMD operates (Richland Chambers
and Cedar Creek Reservoirs). By developing a system to capture water from
the Trinity River and filter it through a series of wetlands, TCWMD is in
effect capturing wastewater that would normally be lost.

Ducks Unlimited was contacted by TCWMD to help with the design of a 240-acre
field scale project on Texas Parks and Wildlife Department land near Richland
Chambers Reservoir. DU designed 4 cells on 240 acres that were capable of
handling 15 million gallons per day with a 7-10 day detention time. Water
will be maintained at depths from 6 to 18 inches and moist soil plants will
be grown to help filter the water. Should the field scale perform as expected
then an additional 1,200 acres will be developed.

The project resulted in a win-win situation for all parties, Texas Parks
and Wildlife gets the needed water supply to manage the area, waterfowl and
wading birds get shallow water wetlands for use, hunters get a new public
hunting area, Tarrant County Water Management District gets a reliable source
of water to help meet future water demands, and environmentally no land or
person is displaced due to the construction of new dams or reservoirs.
