1.         INTRODUCTION

1.1       Sabine River Authority

The Sabine River Authority of Texas (SRA) was created by the Legislature in 1949 as an official agency of the State of Texas.  The SRA was created as a conservation and reclamation district with responsibilities to control, store, preserve, and distribute the waters of the Sabine River and its tributary streams in the Texas portion of the Sabine River Basin.  Figure 1 is a map of the Sabine River Basin.  The Sabine River Authority, State of Louisiana (SRA LA) was formed in 1950 by the Louisiana Legislature.  Representatives from the two States ultimately developed the Sabine River Compact, which is responsible for the allocation of waters in the Basin between the two States.  Representatives of the state legislatures and Congress approved the Sabine River Compact in 1953.  The SRA includes four operational divisions and one technical division: the Gulf Coast Division, Iron Bridge Division, Toledo Bend Division, Lake Fork Division and the Environmental Services Division (Espey, Huston, and Associates, 1985).

            The area of responsibility of the SRA consists of the total contributing watershed of the Sabine River within the state of Texas.  It includes all or portions of 21 counties:  Collin, Franklin, Gregg, Harrison, Hopkins, Hunt, Jasper, Kaufman, Newton, Orange, Panola, Rains, Rockwall, Rusk, Sabine, San Augustine, Shelby, Smith, Upshur, Van Zandt, and Wood.

            The Sabine River has its headwaters in northwest Hunt County at an elevation of about 700 feet.  The river flows eastward and is joined by the South Fork at the intersection of Hunt, Van Zandt, and Rains Counties within Lake Tawakoni.  From Lake Tawakoni the river flows a distance of about 250 channel miles southeasterly to the boundary between Texas and Louisiana near the town of Logansport, Louisiana.  The river then flows southward as the Texas-Louisiana  boundary  and  continues  southward  to  Sabine  Lake  on  the  Gulf  Coast.  The total


Figure 1: Base Map of Sabine River Basin
drainage area of the basin is 9,756 square miles, with 7,426 square miles in Texas and 2,330 square miles in Louisiana (Texas Department of Water Resources, 1984)

1.2       Purpose for Water Conservation

The SRA is committed to providing adequate supplies of high quality water to municipal, industrial, agricultural and recreational users.  Water conservation is an integral element of that effort.

There are a variety of benefits to be gained by implementing water conservation practices.  Using water conservation to reduce demand in water-poor areas and areas of rapid population growth is one way to increase available water supplies without having to develop additional water resources.  This provides economic benefits to the end users of the water as well as the utility responsible for supplying water.  Water rates are likely to stabilize if the large capital expenses of developing reservoirs or other water supply sources can be avoided or delayed.

In environmentally sensitive habitats, water conservation can make water available for continuous instream flows.  Water conservation can reduce the amount of water which is discharged to wastewater treatment plants for treatment prior to discharge into the State's lakes and streams.  In some instances, discharging a reduced amount of treated wastewater into the waterways could improve water quality and enhance the quality of the aquatic habitat.

Holders of water rights of 1,000 acre-fee/year or more, for municipal, industrial and other uses and 10,000 acre-feet/year for irrigation are required to submit a water conservation plan (Title 30, Texas Administrative Code, Chapter 288).  According to the rule, conservation means "those practices, techniques, and technologies that will reduce the consumption of water, reduce the loss or waste of water, improve the efficiency in the use of water, or increase the recycling and reuse of water so that a water supply is made available for future or alternative uses."  The Texas Natural Resource Conservation Commission (TNRCC) is responsible for oversight of these plans.  Plan requirements for water conservation plans for wholesale water suppliers include, as a minimum:

·        Description of wholesaler’s service area including information on population, customer data, water use data, water supply system, and wastewater system.

·        Specification of conservation goals including, where appropriate, target per capita water use, maximum acceptable unaccounted for water, the basis for goal development, and timeframe for achieving goals.

·        A description as to which practice(s) and/or device(s) will be utilized to measure and account for the amount of water diverted from the source(s) of supply.

·        A monitoring and record management program to determine water deliveries, sales and losses.

·        A metering, leak detection and repair program for the wholesaler’s water storage, delivery and distribution system.

·        The requirement that every wholesale supply contract or contract renewal include a requirement that each successive wholesale customer develop and implement a water conservation plan or conservation practices.

·        A drought management plan that includes an education and information program about the plan, notification procedures to identify the initiation and termination of the drought and the corresponding implementation and termination of the drought measures, trigger conditions signaling the start of any identified drought period, and drought water-use measures corresponding to each trigger condition.

·        A reservoir systems operations plan.

·        A means for implementation and enforcement.

In addition to the minimum requirements sited above, the TNRCC provides guidance on additional conservation strategies that may be selected by water wholesalers if they are necessary to achieve the plan’s stated water conservation goals.  These optional conservation strategies can include:

·        Conservation-oriented water rates and water rate structures.

·        A program to assist customers in the development of conservation plans.

·        Any other appropriate practice.

·        A program for reuse/ recycling of wastewater/greywater.

1.3             Conservation Goals

The SRA’s Water Conservation and Drought Contingency Plan, revised December 1999 and March 2002, outlines the means the SRA will use to satisfy each of these requirements.  The SRA developed its water conservation and drought contingency plan goals after reviewing specific information on the hydrologic and water usage characteristics within the Sabine Basin.  The following conservation goals are the basis of this plan. 

·        SRA will target its conservation program towards small local water supply entities within the Upper Sabine Basin, the geographic area upstream of Toledo Bend Reservoir.  These entities have a need for assistance with conservation.

·        The SRA will require conservation and drought contingency planning in all new and renewed water sales contracts.   A copy of the standard sales contract is included in Appendix A.  The time frame associated with this goal is dependent on the various expiration dates of existing contracts and options.

·        SRA will work with state agencies to provide technical assistance to local entities currently without conservation and drought contingency plans. 

-        It will facilitate regional water conservation and drought contingency planning through its participation in the Senate Bill One Regional Water Planning Groups’ activities for the Sabine Basin.  The SRA’s goal is to be active in this process through the current planning period and to be a part of subsequent Senate Bill One planning phases (every five years).

-        The SRA will provide water conservation planning information and assistance on its internet web page with links to TNRCC and Texas Water Development Board (TWDB) sites.

-        The SRA will assist state authorities in providing technical assistance to local entities in plan development.  It is the SRA’s goal to assist all local entities that are required by TNRCC to have a plan to develop those plans.  For those entities not required by TNRCC to have plans, the SRA’s goal is to help them to voluntarily develop plans by January 2005.

·        Through technical assistance the SRA will continue to encourage and support efficient water use and reduced waste.  All new and renewed water sales contracts since 1989 require full water metering, metering repair and replacement, and leak detection and repair.  (A copy of the standard sales contract is included in Appendix A)

·        It is the goal of the SRA that its customers have reasonable levels of per capita use and unaccounted-for water.  The following general standards were developed considering historical data from the SRA’s customers as well as the geographic and hydrologic conditions of the Sabine Basin.  The year 2000 per capita water use of the SRA’s customers should not be in excess of 250 gallons per capita per day (gpcd).  By year 2020, the goal should be a per capita use not to exceed 225 gpcd, and by year 2050, not to exceed 200 gpcd.  Should any of the SRA’s customers fail to meet these goals, the SRA will assist that customer in reducing its per capita use in any way possible, including but not limited to the items outlined in this section.  The SRA’s year 2020 goal for unaccounted-for water for its customers is 20 percent.  The goal for 2050 is 15 percent.  Again, should any of the SRA’s customers fail to meet these goals, the SRA will assist them in any way possible.

·        The SRA will provide current information and education on water conservation and drought management programs.  It maintains a state-of–the-art web page providing the public with current information on water resource management activities, conservation opportunities and real-time data on water supply and quality conditions at www.sra.dst.tx.us.   The SRA will update the information on the web site as new information becomes available.  SRA also distributes over 500 copies of periodic newsletters to inform people in the basin and elsewhere of the SRA’s activities and any new regulations recently enacted.  The SRA’s goal is to distribute this newsletter at least two times per year.  The SRA’s also participates in the Major Rivers Water Conservation program by distributing educational materials to elementary schools throughout the Basin.  It is the SRA’s goal to distribute this Water Conservation program or other similar material every school year.

 1.4      Report Organization          

Section 1 presents background information on the SRA and its service area, the purpose and goals for water conservation, and a description of the sections in this report.

Section 2 evaluates the SRA service area and supply system, including data on basin population and customers, water use, existing supply system, and historical and projected use, and on current conservation measures.

Section 3 of this plan outlines the measures the SRA will use to meet its conservation goals: 

n       education and information programs

n       conservation oriented rate structures

n       universal metering and meter repair and replacement

n       leak detection and repair program

n       recycling and reuse programs

n       technical assistance in development of conservation plans

n       coordination with Regional Water Planning Groups planning in the Sabine Basin.

Section 4 is the SRA’s Drought Contingency Plan.  This plan includes an education and information program about the plan, notification procedures on initiation and termination of drought conditions and measures, trigger conditions and drought water-use measures associated with each trigger condition.  


2.         Service Area and SYSTEM EVALUATION

2. 1.        Water Supply and Wastewater System

            The SRA owns and operates four major projects in the River Basin: the Orange County Canal System, Iron Bridge Dam and Reservoir (Lake Tawakoni), Lake Fork Dam and Reservoir, and Toledo Bend Dam and Reservoir.  The TNRCC permit limits for each system are listed in Table 1.

*          Because of the SRA’s joint use permit, those with contracts to divert Lake Fork water may divert from Lake Tawakoni as long as the actual diversion does not exceed the diversion right.

Water diverted from the Orange County Canal System is used primarily for municipal, industrial, and irrigation purposes.  The three reservoirs serve as sources of water supply and provide recreational opportunities.  Toledo Bend Dam is also equipped to generate hydroelectric power with releases from the reservoir.  Toledo Bend is a joint project of the SRA of Texas and the SRA LA.

            The Gulf Coast Division operates the Gulf Coast Canal System that serves the Orange County area.  There are 11 diversions from the canal with a contract maximum totaling 59,532 acre-feet per year (53.15 million gallons per day).  The pump station has a design capacity of approximately 360 million gallons per day (mgd) and the conveyance capacity is 346,000 acre-feet per year (309 mgd).  The pump station is located on an intake canal off the Sabine River and lifts water from the River to the main canal.  The main canal is approximately 30 miles long and has over 45 miles of lateral canals that branch off to serve customers in the area.  Customers include industries, an electric generating system, two rice farms, and one municipality.  In past years SRA has served up to 8 rice farms with a total of 6,000 acres.  The two rice farms presently served irrigate a total of 480 acres at a rate of $9.25 per acre-foot.  The water is released by metered gates, which are manually operated and recorded by SRA personnel on an as-requested basis.  The present acreage of rice farming is projected to continue to decrease.

            The SRA encourages water conservation in all of its water sales.  As part of each Water Sales Agreement an Article is included requiring all customers to develop and implement water conservation plans and to implement the SRA’s conservation and drought contingency plan.  If a customer resells SRA water, it is required to include the requirement for conservation plans for each successive user of the water.  SRA also routinely checks its canals for leaks and damage and repairs any problems found in the earthen walls or pipes immediately.

            In an effort to minimize any waste throughout its system, the SRA has installed four forty-eight inch Marsh McBirney Model 280 magnetic meters, one twenty-four inch water specialty Saddle meter, and nineteen sixteen inch open flow water specialty meters.  The particular meter assigned to each metering site is based on usage.  The meters are read on a daily basis by SRA personnel and recorded in a journal at the Gulf Coast Division office.

            The Gulf Coast Division operates one of the two wastewater treatment plants owned by the SRA.  In addition, the Division is the contract operator for one other wastewater treatment plant.  The plant at this Division is owned by the SRA and treats approximately 2,500 gallons per day of domestic wastewater from a plastics warehouse.  This facility has 15 to 20 employees while the one operated under contract treats approximately 8,000 gallons per day of domestic wastewater from the Cow Bayou Rest Stop located on IH 10 (Personal Communication with Albert Gray, Sabine River Authority, 1992).

Toledo Bend Dam and Reservoir, managed by the Toledo Bend Division, lies on the state boundary of Texas and Louisiana.  The reservoir yield of 2,086,600 acre-feet per year (1,862.7 mgd) is shared equally between the two states.  The storage capacity of the reservoir is 4,477,000 acre-feet.  Several small diversions serve municipal uses with contracts totaling 2,118 acre-feet/year.  In addition to serving as a water supply source, Toledo Bend Dam provides hydroelectric power that represented a non-consumptive use of 218,040 af/y in 1996.  The hydroelectric plant is located on the south abutment of the dam.  Two units with Kaplan turbines and two water-cooled generators have produced an average of almost 230 million-kilowatt hours annually since 1970.

Iron Bridge Dam and Lake Tawakoni are located in parts of Hunt, Rains, and Van Zandt Counties and are managed by the Iron Bridge Division.  The reservoir has a storage capacity of 888,137 acre-feet and a yield of 238,100 acre-feet per year (212.6 mgd).  There are 12 diversions with a contract maximum totaling 238,401 acre-feet per year (212.8 mgd) from Lake Tawakoni.  This includes a contract with the City  of Dallas for 80 percent of the yield.  The Iron Bridge Division operates the other wastewater treatment system owned by the Authority.  This system treats wastewater from Wind Point Park through a no-discharge irrigation system.

A rolled-earth fill dam contains Lake Fork Reservoir, located in Wood, Rains, and Hopkins Counties and operated by the Lake Fork Division.  The reservoir has a storage capacity of 675,819 acre-feet and a yield of 188,660 acre-feet per year (168.4 mgd).  Lake Fork has 20 water contracts and options committing 188,190 acre-feet per year (168.8 mgd). 

As part of its conservation/pollution prevention plan, the SRA encourages each of its customers to formulate a plan to conserve water and prevent pollution on a continuing basis.  Customers are notified that they can contact SRA for assistance in formulating this plan.  SRA requires all of its customers to avoid wasting water.

            The TNRCC has notified the SRA that this Conservation and Drought Contingency Plan is administratively complete.  As a result the SRA Board of Directors has approved a resolution adopting this Conservation and Drought Contingency Plan, and the resolution is included in Appendix B.   

2.2       Sabine Basin Population, Historical and Projected Use

            The Sabine Basin includes 21 counties lying entirely or partially within the basin.  The population currently served by the SRA is not easily definable since many SRA-supplied entities receive water from multiple sources and distribute water to multiple customers.  Most of the population now served by the SRA is out of the Sabine Basin.  Sabine Basin population and water use figures are used for the purposes of this report.

            Historically, the population of the Sabine Basin in Texas was 442,358 in 1990, and the amount of water used for municipal purposes was 68,229 acre-feet, or approximately 138 gpcd (TWDB). 

            The TWDB develops population and water use projections for the State.  Various growth scenarios were created for the 1996 update of Water for Texas Today and Tomorrow.[1] Using the TWDB “Most Likely” population scenario, the average population growth rate for the Sabine River Basin is expected to be approximately 0.7 percent per year for the 60-year period from 1990 to 2050.  Using the TWDB “Most Likely” municipal water demand scenario which assumes water conservation, municipal water use in the basin is expected to increase by 0.46 percent per year over the 60 year period and reach 86,960 acre-feet per year (124 gpcd) by 2050.  Based on TWDB information, the per capita municipal use is expected to decrease from 146 gpcd in 1990 to a projected 124 gpcd in 2050.  The State of Texas' average municipal use is 181 gpcd.  The Sabine Basin per capita demand is therefore 20 percent below the State average.  Figures 2 and 3 are graphical representations of the projected basin population and water needs, respectively.  As Figure 3 illustrates, the TWDB is projecting minimal increases in municipal use, but large increases in overall basin needs.  The TWDB is projecting substantial increases in uses of water for manufacturing in Gregg, Harrison, and Orange Counties and in steam electric uses in Orange and Rusk Counties.  Table 2 provides population and water demand projections for each Sabine Basin county through year 2050.  Table 3 presents a summary of total water sales by the SRA from 1980 to 1997.  Annual sales to the four divisions for this period averaged 125.22 million gallons per day.  Tables 4 through 7 present the sales history for each division for the past seven years.  The Gulf Coast Division has the largest number of customers, and the Iron Bridge Division has the highest average sales for the years 1991 to 1993.  The SRA currently has approximately 30 contract customers.  A total of 11 of those customers obtain service from the Gulf Coast Division system that has an excess of available water supply of over 1.0 million acre-feet per year.  Within the Upper Sabine Basin, which is projected to have water shortages, of the 13 municipal customers, only the City of Dallas has current usage over 4.0 mgd.  All of the other cities combined have a total 1997 demand of 15.0 mgd.
