Goliad WWTP - Secondary Wastewater Treatment Plant in Goliad, Texas

Goliad WWTP is a municipal wastewater treatment facility located in Goliad, Texas, serving a population of around 1,970 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring removal of organic matter and suspended solids before discharge. The plant has a designed capacity of 1,324.89 thousand gallons per day and an average daily discharge volume of 995.56 thousand gallons per day. As a US facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into local receiving waters, which ultimately drain into the San Antonio River basin and then to the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region.

The plant discharges into local waterways that are part of the San Antonio River watershed, which flows into the Gulf of Mexico. This coastal basin supports diverse aquatic life, including fish and migratory birds. The secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the Gulf.
