Desalination and ASR Feasibility Assessment

No Drought
Lovelady well height: 487.6 ft-msl (165.7 ft-Depth to Water)
Barton Springs: approximately 62 cfs 10-day average

The Edwards Aquifer has been considered a vast source of inexpensive, high-quality drinking water for many years. However, restrictions have been placed on production from the Edwards in recent years, and rising demands have increased faster than the provision of other additional sources. With the past significant reliance on the Edwards Aquifer, other potential sources warrant further consideration. Potential sources within the boundaries of the BSEACD that are being minimally used, if at all, include the Middle and Lower Trinity aquifers, and the brackish portion of the Edwards. One prospective new water supply source is the large quantity of brackish groundwater in the eastern portion of the District. Texas Disposal Systems is located on this “donut hole” which is outside the jurisdiction of the BSEACD. Multi-port wells installed here have provided data necessary to analyze the feasibility of desalination of the brackish
groundwater; management of desalination treatment residuals; and using the treated water for aquifer storage and recovery (ASR).
