Why it Matters

Population growth in the Hill Country is creating unprecedented wastewater discharge! This “effluent waste” causes undesirable algae growth that strangles the ecological balance of our streams, hurting aquatic wildlife. It can also contaminate aquifers, wells and drinking water.

State law allows treated wastewater to contain phosphorus and nitrogen, which causes big problems in river ecology. Also, there is no treatment for pharmaceutical chemicals that can contaminate aquifers.

Cities that recently applied for discharge permits:

  • Dripping Springs
  • Spring Branch
  • Wimberley
  • Buda
