Cedar Hill, Duncanville and Grand Prairie contracted with TRA to construct a raw water intake structure and raw water pump station at Joe Pool Lake. Phase I of the Lakeview Regional Water Supply Project, completed in 1986 before the lake filled, involved only those components that would have been cost prohibitive if constructed after the impoundment of water.  TRA and the three cities have formed the Lakeview Regional Water Supply Project to provide treated water. TRA and the participant cities continue to plan for implementing a regional water treatment plant and distribution pipeline when the demand for water makes it feasible.

Lakeview Regional Water Supply Project

TRA financed, designed and constructed the Summit Regional Water Storage Project, 
the eight million-gallon ground storage tank serve the needs of Duncanville and Cedar 
Hill. Water supplied under the cities’ wholesale water contracts with Dallas is delivered 
into the tank. The project’s high service pump stations for each city deliver each city’s 
needs into their systems, and the supporting pipelines and appurtenances necessary 
to  make the project operational for the benefit of both cities are a part of the project.

The Grand Prairie Water Project is an elevated storage tank and water transmission lines that were financed and constructed by the Authority for Grand Prairie. This project includes a contract between TRA and Grand Prairie for replacement of bonds.


Consisting of a conveyance pipeline and pumping facilities, TRA’s Coppell Water 
Supply Project provides Coppell with potable water from Dallas’ Elm Fork treatment 
plant. To accomplish this, TRA entered into a contract with Dallas to purchase treated 
water, which is then delivered to Coppell. The pipeline constructed by the Authority for 
the benefit of Coppell is capable of transporting 9 mgd of treated water.
Huntsville Regional Water Supply System Up to 8 million gallons of water per day are 
supplied to the City of Huntsville by TRA’s 
Huntsville Regional Water Supply System. 
The system, located north of Huntsville, 
provides service to a population of 
approximately 34,000 people.  Raw water for 
this project is supplied by TRA through a 
withdrawal facility in the headwaters of Lake Livingston. Transmission lines move the water 
four miles to the treatment plant in northeast 
Walker County.
After completing the treatment process, finished water is pumped 10 miles to ground 
storage facilities in Huntsville. At the storage facilities, the treated surface water is 
blended with well water from the city’s original groundwater system. In 1996, 
approximately 54,000 feet of distribution pipeline facilities were added to the system in 
order to provide potable water to the Texas Department of Criminal Justice’s Ellis and 
Estelle prison units located in northern Walker County. 

In 1999, TRA entered into an agreement with the City of Huntsville to provide 6 mgd of 
partially treated water to the Tenaska power generating plant in Grimes County, 30 
miles from Huntsville. Thirty miles of pipeline were constructed, the capacity of the 
rawwater intake structure was doubled to 16 mgd and the water plant capacity was 
increased to accommodate an additional 8 mgd of clarified water.
TRA supplies water to the City of Livingston through the Livingston Regional Water Supply System. Raw water for this regional water treatment system is withdrawn from TRA’s Lake Livingston.  In 1992, the plant underwent expansion to double its treatment capacity from 1 mgd to 2 mgd. The expansion was necessary in order to provide potable water for the Texas Department of Criminal Justice’s Terrell unit, which is located outside of Livingston directly across the farm road from the treatment plant. Lakeview Regional Water Supply Project

Raw water is withdrawn from Lake Livingston and treated at the Trinity County Regional Water Supply System before being distributed to Trinity, Groveton, Westwood Shores Municipal Utility District, and the Glendale, Trinity Rural and Riverside water supply corporations

This innovative project withdraws raw water from Lake Livingston via a series of shallow wells placed in existing sand and gravel deposits on the Trinity shoreline of the lake. The deposits act as filters and reduce treatment costs.

Significant cost savings were realized by the participants in this regional water system because of the minimal treatment facilities that were required in the Trinity System's treatment plant.
