Bayou Vista WWTP - Secondary Treatment Plant in Bayou Vista, Texas

Bayou Vista WWTP is a municipal wastewater treatment facility located in Bayou Vista, Texas, a small coastal community in Galveston County. The plant serves a population of approximately 1,770 residents and operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES). The plant provides secondary treatment, a standard level required for most municipal facilities in the United States. Its designed capacity is 1,514.16 thousand gallons per day, with an average discharge volume of 946.35 thousand gallons per day, indicating operational headroom. As a coastal plant within 10 km of the Gulf of Mexico, it must comply with stringent discharge permits to protect sensitive marine environments. The treated effluent is discharged into local waterways that drain into Galveston Bay and ultimately the Gulf of Mexico. This region supports diverse aquatic life, including commercial and recreational fisheries, and the plant's operations are critical to maintaining water quality in the bay ecosystem.

The plant discharges into receiving waters that flow into Galveston Bay, a large estuary on the Texas Gulf Coast. Galveston Bay supports a rich ecosystem of fish, shellfish, and migratory birds, and is a vital economic resource for fishing and tourism. The bay's health depends on careful management of nutrient and pollutant loads from coastal communities like Bayou Vista.
