The mission of The Trinity Edwards Springs Protection Association (TESPA) is to protect the Trinity and Edwards aquifers from over pumping, the springs that flow from this interconnected system, and the property rights of landowners who depend on and wish to conserve this precious natural resource.

The Trinity Aquifer is under siege. The springs and creeks which emanate from this natural resource, and the property rights of landowners are at risk. Today, more than ever before, this precious natural resource, which is vital to the ecology and economy of the Hill Country, is in peril. As the population in Central Texas continues to grow, water suppliers are searching for new sources of water, and the Trinity Aquifer is a target. Although groundwater pumping from the aquifer is already occurring at an unsustainable rate, more groundwater development projects are in the works. Current groundwater law facilitates the mining of our aquifers and elevates groundwater development over groundwater protection. TESPA is taking legal action and advocating for policy changes to ensure that groundwater in Texas is sustainably managed and landowners' property rights are protected.

Please attend BSEACD's informational meeting on June 18th to learn more about Electro Purification's permit application for 2.5 MGD and staff's recommendation to the Board of Directors. The meeting will be held at the Wimberley Community Center at 6:00 PM on June 18th.


On Wednesday June 6th, the State Office of Administrative Hearings (SOAH) Administrative Law Judge (ALJ) issued a ruling dismissing TESPA's Motion for Summary Disposition in the Needmore Water LLC Contested Case, granting Needmore and BSEACD's Motions and cancelling the Hearing on the Merits, which was scheduled for July 19th.

The result of this decision is that Needmore's application will now at some point in the near future go before the BSEACD Board of Directors for final approval. This is a huge legal set back that means Needmore is now one step closer to gaining approval to pump 289,000,000 a year from the already taxed Trinity Aquifer.

In February, TESPA filed a Motion for Summary Disposition arguing that BSEACD erred in granting Needmore a temporary and regular permit for 289,000,000 gallons of groundwater a year because Needmore was not eligible to apply for a temporary permit. House Bill 3405 required that to be eligible to apply for a temporary permit, a person had to be operating a well at the time the Act became effective. TESPA argued that BSEACD...


On Tuesday night, concerned landowners in Wimberley and Driftwood flooded the sanctuary at Saint Stephen's Episcopal Church to attend TESPA's meeting about EP's groundwater production application at BSEACD and to learn about what options are available to landowners to protect their groundwater. Last July, EP submitted an application to BSEACD to pump 2.5 MGD a day of groundwater from the Trinity Aquifer. BSEACD predicts that pumping from EP's well field at this rate will cause over 300 feet of drawdown within one year from wells 2 miles away. Learn more here.
