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.

Landowners in Bexar County may be facing an EP like situation despite the fact that a groundwater conservation district - the Trinity Glenrose GCD - exists in Bexar County. This is because Trinity Glenrose's enabling legislation exempts public water supply wells completed before September 1, 2002 from any regulation.

Texas Water Supply Company, LLC has plans to pump 32,000 acre feet from the Trinity Aquifer from two well fields to the south and to the east of Camp Bullis . See article in the San Antonio Business Journal. The area is in GMA 9 but on the border of GMA 10. Because Trinity Glenrose has no authority to regulate production from these wells, the developers can pump unlimited amounts of water even if doing so draws down nearby wells. Under the Rule of Capture, nearby landowners cannot sue the developer if their groundwater is depleted.

This situation is yet...
