This document discusses water resources for the state of Texas. It outlines the historic and projected population growth for Texas, which is expected to increase significantly from 46.3 million currently to over 50 million by 2060. The 2012 State Water Plan is mentioned as providing strategies to address water needs. The document also describes two research projects supported by the Texas Water Development Board on direct potable reuse and water quality testing in Big Spring, Texas. Direct blending of purified water into existing water supplies is highlighted as a potential solution for Wichita Falls and Big Spring. Contact information is provided for Kathleen Jackson at the Texas Water Development Board to discuss these issues further.

Editor's Notes
- More focus has been on TWDB and water issues due to 1. Drought: -Less than half the state is under moderate to exceptional drought conditions. Conditions haven’t changed since last week. -Saw improvements in south Texas and the southern High Plains over the past week, but drought worsened in North Texas. -One patch of exceptional drought includes Dallas, Fort Worth, Weatherford and Mineral Wells and another patch includes the Wichita Falls area.
- More focus has been on TWDB and water issues due to: 2. Population Growth In order to keep up with our ever growing population and roughly 1,000 people moving to Texas everyday, we must ensure we have enough water! In 2060, the population of Texas is projected to be nearly 7 times the size it was in 1950. The state’s population is expected to grow by 82% in the next 50 years, growing from 25 million to 46 million people.
- State Water Plan (Future Water Needs, Meeting Water Needs Includes Reuse, etc.) Beneficial to have DPR included in current and future State Water Plans. Critical to begin planning and development of required information at an early time even though DPR project may not be needed for several years Water Reuse is a viable strategy: Water reuse is expected to account for more than 10 percent of all new water supplies from recommended water management strategies in 2060.
- In 2011, we completed three reports that looked at the history of water reuse in Texas, the state of water reuse technology, and a research agenda for water reuse. Note: at that time emphasize was on Indirect Potable Reuse TWDB has received funding for ongoing research studies - Critical to apply sound science and technology developed by national and state of Texas performed research and DPR plants’ operating data TWDB / Local Sponsors Research to Develop a DPR Resource Document 1. Evaluating the Potential for Direct Potable Reuse in Texas. Scheduled completion date: December 2014 The goal is to develop a resource document that provides scientific and technical information for the implementation of direct potable reuse projects in Texas. The guidance document will identify contaminants of concern and define performance targets for constituents for two real-world case studies. In addition, the project will evaluate treatment technologies, quantify risk assessment, and provide pilot protocols. Current status: The consultant is starting to compile the guidance document. The draft guidance document is due to TWDB in December 2014. The team will review and provide comments. TWDB Research Effort to Perform Sampling and Testing of the CRMWD Reuse Project 2. Testing Water Quality at the Raw Water Production Facility in Big Spring, Texas. Scheduled completion date: June 2015 First direct potable reuse facility in Texas and in the nation. The goal is to demonstrate that direct potable reuse is safe and a viable alternative for producing potable water in Texas. Test water quality at various locations in the treatment process (test for microbial pathogens and chemicals of emerging concern). Develop a guidance document with monitoring guidelines for direct potable reuse projects in Texas. Current status: The consultant performed the first set of water sampling in July 2014 to develop a baseline. Currently, the sampling protocol is being finalized. The consultant has to address a few concerns related to the challenge testing. Further sample testing is on hold due to plant operation issues.
- Emerging Water Supply - More and more, the TWDB is seeing entities explore and construct systems that utilize the water already available in their systems. DPR implemented and operated in a safe manner can be a viable water supply – relatively quick compared to building new reservoir Examples of reuse projects funded by TWDB - The TWDB has been funding re-use projects for a long time City of Wichita Falls – agenda item at board mtg next Tues. -$33,545,000 loan and $252,597 in loan forgiveness from the Clean Water State Revolving Fund to finance planning, design and construction costs related to the development of an indirect, potable reuse system. This funding request is to replace the temporary direct potable reuse system with a permanent indirect reuse system to supplement the raw water available for the City to treat within Lake Arrowhead. -As of 10/13/2014, total reservoir storage is 23% full 2. Big Spring – Refer to it as direct blending rather than direct potable reuse. (WAITING ON PROJECT DETAIL FROM JEFF) -Heading there next Tuesday to tour following board meeting in Abilene. 3. Brownwood 2012 - construction commitments for $12 million DFund for a 1.5 MGD direct potable reuse. Emergency project, received rain so haven’t started construction. 4. El Paso – starting direct reuse system now (not blending but putting directly into distribution system); expect to go online in 2018 Difficulties encountered: Affects downstream users - no longer putting that water back into river Requires higher level of treatment than conventional sources of water Push back from some concerned citizens re: “toilet to tap” Getting permitting in a timely fashion
- Thank you for giving me the opportunity to speak! Again, as I mentioned earlier, we want you to actively participate in planning for future water needs to achieve our common goal of "developing water for Texas." Your charge – TWDB has the funding, we have the science, but it’s up to local communities to have the VISION and INVEST in the future We want the broader communities to be engaged that already have a network and are trusted – i.e. Chamber of Commerce, TWCA, TRWA, Farm Bureau, Cattle Raisers Let us know if there is an opportunity for me or one of the other board members to speak in your community and we will make every effort to attend. Pray for Rain, Plan for Drought! I encourage you follow me on twitter: @twdb_kathleen!
