Westside STP 2 - Smith County, Texas Wastewater Treatment Plant

Westside STP 2 is a municipal wastewater treatment plant located on County Road 46 in Smith County, Texas, serving a population of approximately 64,000. The plant is situated in an inland area of northeastern Texas, more than 50 kilometers from the coast, and contributes to the region's water management infrastructure. As a facility serving a medium-sized agglomeration, Westside STP 2 is expected to meet secondary treatment standards under the US Clean Water Act, which is administered through the National Pollutant Discharge Elimination System (NPDES) permit program. The Texas Commission on Environmental Quality (TCEQ) typically issues permits for such plants, ensuring compliance with federal and state water quality regulations. The treated effluent from Westside STP 2 likely discharges into a local waterway that drains into the Sabine River basin or the Neches River basin, both of which flow into the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region's rivers and reservoirs.

The plant's discharge enters a local tributary within the Sabine or Neches River basin, both of which drain into the Gulf of Mexico. These river systems support diverse aquatic life, including fish and migratory birds, and are important for regional water supply and recreation. The downstream environment includes ecologically sensitive areas such as wetlands and estuaries that benefit from effective wastewater treatment.
