Overview
- TCEQ commissioners on Oct. 22 approved the wastewater discharge permit for the Guajolote Ranch treatment plant.
- The approval advances Lennar’s roughly 3,000-home project on about 1,100 acres in northwest Bexar County.
- The plant could discharge up to 1 million gallons per day into Helotes Creek, which feeds the Trinity and Edwards aquifers that supply nearly 2.5 million people, including 15% of San Antonio’s water.
- Lennar says a membrane bioreactor system will exceed regulatory standards and be run by top-level operators, citing similar facilities in the region.
- Community groups cite a 2020 city-funded study warning of significant recharge degradation and say emerging contaminants and operational failures pose unacceptable risks, and they plan rehearing and court appeals while local officials weigh PID financing.
