The mission of The Trinity Edwards Springs Protection Association (TESPA) is to protect the Trinity and Edwards Aquifers, the springs that flow from this interconnected system, and these precious waters for the people and wildlife who use and depend on them.
The Trinity Edwards Springs Protection Association (TESPA) was founded in 2015 to fight the threat posed by Electro Purification (EP) with its proposal to pump 2.5 million gallons per day from the Trinity Aquifer in Hays County between Kyle and Wimberley. Through court filings, administrative law filings, and arousing public outcry, TESPA and local citizens were able to defeat this effort, and EP is no longer a threat.
CHALLENGES PERSIST. TESPA continues to monitor and protect groundwater in the region. Our work is far from over. The Hill Country is hot and dry right now. Jacob’s Well has been closed since 2022. Yet, development continues and investor-owned utilities like Aqua Texas continue to violate their groundwater permits. Local groundwater conservation districts do their best to enforce and apply penalties while avoiding lawsuits that tight budgets cannot support.
TESPA REMAINS ON CALL. TESPA board members are local landowners who not only care about our natural water resources, but are willing to take up a big legal stick to protect them. Our members and supporters understand that litigation is not always an action of last resort—but can sometimes be just the deterrent or tool we need to get the protection we deserve.
