An ASR is a viable solution. Groundwater rights can be fully exhausted on aregional basis and stored in an ASR. Diverted flows from rivers that exceed baseflood flows could also be stored with some treatment. The costs associated withan ASR would be dependent on the size of the void. The pipe network,transmission lines, and water treatment would also be cost to consider.11.1.9 The Simsboro AquiferThe Simsboro Aquifer water supply strategy involved the development of wellfields over the Simsboro Aquifer. The project was reportedly headed by the SanAntonio Water System (SAWS). SAWS and GBRA in 2008 were approached bya group of landowners, known as the Brazos Valley Water Alliance, to develop aproject that would supply 200,000 ac-ft/ yr to participants.The Brazos Valley Water Alliance was formed in 2002 to represent landownersover the Simsboro Aquifer. The Alliance has approximately 180,000 acres of landand more than 1,200 landowners. The Simsboro Aquifer is a member of theCarrizo/ Wilcox Aquifer which is capable of producing high quality water. Afterfurther investigation with SAWS no formal announcement or decision has beenreached to continue evaluating this strategy. Additional studies are needed to fullyevaluate this option.11.1.10 Weather ModificationThe weather modification strategy involves the practice of seeding clouds toincrease precipitation. Licensed professionals within the planning region wouldseed clouds with iodide. The practice does not guarantee precipitation and waterquantity estimates can not be measured. The strategy would be intended forcropland, livestock, and aquifer recharge. The strategy is still being studied andhas been practiced since 2005 in some Texas counties.Klotz Associates Project No. 0972.000.000January 201011-10Caldwell County Regional Water and Wastewater Planning StudyFinal Report
Weather modification is a good strategy but is not considered an applicable orviable solution to meet the future water needs of Caldwell County. Withoutconsistent results it can not be relied on to yield definite amounts of rainfall.11.1.11 Rainwater HarvestingThe rainwater harvesting management strategy captures and stores runoff fromrooftops for potable and non-potable use. In some instances this approach canadequately supply the needs of households and businesses.Rainwater harvesting is a strategy that can assist in the demands projected byreducing per capita consumption. The effects of rainwater harvesting if consumersparticipated on a city wide basis could have great results. Reducing demand on aregional level would decrease the cost associated with developing new watersources or delay the timing. The Region L Water Plan estimated the cost of waterdeveloped by rainwater harvesting as $2,000 per ac-ft. This cost is consideredhigh. The cost associated with this strategy could be shared cities andhomeowners for existing homes. New development could be given incentives forinstalling systems on homes and buildings. Changes in city developmentstandards could also require such systems.11.1.12 Water Conservation StrategyThe water conservation strategy is suggested to be part of every watermanagement plan. It involves implementing programs and practices that willdecrease water use per capita.Municipally this approach is done by the use of low flow plumbing fixtures,selection of water efficient appliances, modifying landscaping or xeriscaping,addressing plumbing repairs, and modifying personal behavior.Agricultural conservation methods include installing low energy precisionapplication (LEPA) irrigation systems and furrow dikes.11-11Klotz Associates Project No. 0972.000.000Caldwell County Regional Water and Wastewater Planning StudyJanuary 2010Final Report
