| Huntsville Regional Water Supply
System
TRA built, owns and operates this water system under contract with the
city of Huntsville. The system provides service for a population of approximately
34,000.
Raw water for this project is provided by TRA through a withdrawal facility located in the
headwaters of Lake Livingston. It is processed in an 8 mgd treatment plant and pumped to
ground storage facilities in Huntsville.
| During
1998 the Authority was involved in extensive
negotiations, engineering, and design activities that
will lead to a substantial improvement to the raw
water withdrawal facilities and the treatment plant.
This is the result of an agreement between Huntsville
and Tenaska Frontier Partners, Ltd. to provide 6 mgd
of partially treated water to be used for cooling
purposes at an 830 megawatt natural gas fired
electrical generating station in Grimes County.
The
improvements at the treatment plant will include two
65-foot diameter (4 mgd) solids contact clarifiers
with tube settlers, additional chemical feed
equipment, a new sludge holding pond, and related
piping, valves, and pumping. Improvements at the raw
water pump stations were needed in order to deliver
additional water to the treatment plant. This includes
the addition of two 8 mgd and two 4 mgd pumps, switch
gear emergency generators, related piping,
instrumentation, and controls.
The suction
piping at the new intake structure was extended to a
deeper elevation in the main river channel which will
increase the quantity and improve the quality of the
water that is pumped to the plant for treatment. Spin
off benefits will include more redundancy within the
system and the elimination of a long-term raw water
quantity and quality problem. Construction was funded
by a $9.3 million sale of taxable revenue bonds at
TRA's February 1999 Board of Directors meeting. Water
was available for use by Tenaska in the spring of
2000.

The
Environment Protection Agency honored the Huntsville
Regional Water Supply System by awarding it the
regional Environmental Excellence Award for FY 1999.
The Huntsville Regional System was recognized as the
best operated and maintained |
| facility of its
category in EPA's Region 6. EPA Region 6 includes
literally hundreds of similarity sized facilities in
Texas, New Mexico, Oklahoma, Arkansas, and
Louisiana.

Livingston Regional Water Supply System
TRA supplies water
to the city of Livingston through the Livingston Regional Water Supply System. The system
was originally sized at 1 mgd, but was enlarged to 2 mgd in 1992 in order to provide for
the water needs of the Texas Department of Criminal Justice's Terrell Unit that was built
across the Farm Road from the water treatment plant.

During 1997 the Livingston Regional Water Supply System was awarded the Environmental
Protection Agency's Environmental Excellence Award. In receiving this award the Livingston
System was recognized as being the best facility in its category (serving a population of
5,001 to 15,000) in EPA's Region 6. EPA's Region 6 includes literally hundreds of
similarly sized facilities in Texas, New Mexico, Oklahoma,
Arkansas, and Louisiana.Trinity

Trinity County Regional Water Supply System
Raw water is
withdrawn from Lake Livingston and treated at the plant west of the city
of Trinity before
being distributed to Trinity, Groveton, Westwood Shores MUD, and the Glendale, Trinity
Rural and Riverside Water Supply Corporations. This project
withdraws raw water from Lake
Livingston via a network of shallow wells placed in natural sand and gravel deposits on
the Trinity County shoreline of the lake.
TRA's Southern Region Management
initiated discussions with the system's
customers
on options for providing additional water. In 1999, TRA secured
a Texas Water Development Board planning grant to
evaluate various alternatives to increase the
dependable water supply in the system.
The Environmental Protection Agency honored the Trinity County Regional Water
Supply
System by awarding it the regional Environmental Excellence Award for FY
1998. The Trinity
County System was recognized as the best operated and maintained facility of its category
(serving a population of from 5,001 to 15,000) in EPA's Region 6.
EPA Region 6 includes
literally hundreds of similarly sized facilities in Texas, New Mexico, Oklahoma, Arkansas,
and Louisiana.

Lakeview Regional
Water Supply Project 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 project, completed
in 1986 before the lake
was filled, involved only those components which 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.

Tarrant
County Water Supply Project Five
cities in northeast Tarrant County are served by this water treatment system. Originally
established in 1974 to provide 6 MGD of treated water for the cities of Bedford and
Euless, this project has been expanded three times. In 1980, the plant's service area was
expanded to include the City of Colleyville and parts of Grapevine and
North Richland Hills. |
Today, the Authority's Tarrant County Regional System is capable of providing more than
72
MGD of water to the five cities with a population numbering over 172,000. The system will
ultimately deliver in excess of 100 MGD to the cities of the system.
