Livingston Regional Water Supply Project

Because the City of Livingston and the Trinity River Authority had the
forethought to prepare for the future, citizens of Livingston can be assured of having a reliable source of water for many years to come.

The Trinity River Authority issued $3.775 million in revenue bonds to finance construction of the Livingston Regional Water Supply System.

Prior to the Authority's water project, Livingston had been facing both water quality and quantity problems. Construction of the Livingston system solved both.

The Trinity River Authority's Livingston Regional Water Supply System
began supplying treated water to Livingston in July 1981.

In 1991, as a part of its construction of the Terrell prison unit in Polk
County, the Texas Department of Criminal Justice contracted with the City of Livingston for the delivery of drinking water to the facility.

The Authority issued $1.6 million in revenue bonds to expand the treatment plant and construct a 150,000 gallon elevated storage tank at the prison unit.

The water treatment plant is now capable of treating 3.0 million gallons of
water a day. Raw water for this project is supplied by the Authority from
nearby 90,000 surface acre Lake Livingston.

Transmission lines convey raw water to the plant for treatment. After
treatment, the water is stored in the clearwell and pumped to the city and the prison unit via separated high service pumps and transmission lines.

Treatment Process Results In Quality Water

Raw water from Lake Livingston is pumped to the plant through one mile of 12-inch pipeline.

The treatment process involves the use of chemical addition to supplement
mechanical procedures resulting in clear, clean, safe drinking water.

The chemicals utilized, along with the application and purpose, are listed

Alum: coagulation or turbidity removal

Polymer: coagulation and sedimentation

Activated Carbon: taste and odor control

Chlorine Dioxide: taste and odor control

Chlorine: disinfection

Sodium Hydroxide (caustic soda): pH control

Flouride: prevention of tooth decay

Raw water passes through two clarifier basins where turbidity removal by
coagulation and sedimentation occurs. The sediment is stored in retention
ponds for disposal.

The clarified water is then filtered and the final treatment step involves
disinfection and pH adjustment prior to entering a 500,000 gallon clearwell
storage tank.

The treated water is pumped to the City of Livingston through five miles of
12-inch transmission line and to the prison unit through 0.5 miles of 10-inch transmission line where it is stored in a 150,000 gallon elevated storage tank.

Throughout the process, the various chemicals are added to achieve
clarification, water stability and disinfection resulting in water of the highest
quality which meets or exceeds the standards set by the Texas Natural
Resource Conservation Commission and the Environmental Protection

Plant Expands To Provide Water For
Terrell Prison Unit

In 1991, the Authority issued $1.6 million in revenue bonds to finance the
construction of a plant expansion to serve the Terrell prison unit.

The expansion, which increased the plant's design capacity to 3.0 million
gallons per day, included the installation of new raw water pumps, a new filter unit to operate in conjunction with the exsisting filter, and two new
high-service pumps were added to service the prision.

A 10-inch PVC pipeline was constructed to carry water to a 150,000 gallon elevated storage tank that was constructed as part of this project.

The Livingston Regional Water Supply System began providing water to the prison unit in 1993.

The Terrell prison unit currently uses approximately 450,000 gallons per day.

The Trinity River Authority and The City of Livingston Deliver Quality Drinking Water

As we look to the future, the partnership between the Trinity River Authority and the City of Livingston will continue to benefit the citizens of this area by providing a dependable supply of quality drinking watrer.

An increasingly complex and changing regulatory environment and rapidly
developing treatment technologies make it a challenging task to provide
clean, safe drinking water at a reasonable cost.

By designing the Livingston Regional Water Supply System as a regional
system, the Authority built a treatment plant that can be easily expanded to
meet the growing water needs of the Livingston area.

USGS Stream Flow Monitoring Stations

The Trinity River basin in the symbol of the State of Texas is linked to a USGS summary page listing all of the monitoring stations in the Trinity River basin. Each text box and its associated red monitoring station symbol is linked to a USGS page that calculates and graphs the river flows for the previous two weeks for that monitoring station.
