Airport WWTP 3 - Galveston, Texas Wastewater Treatment Plant

Airport WWTP 3 is a municipal wastewater treatment facility located on Sky Master Road in Galveston, Texas, serving a population of approximately 14,000. The plant is situated in Galveston County, a coastal region along the Gulf of Mexico. As part of the city's wastewater infrastructure, it plays a key role in managing local sewage and industrial flows. The plant has a designed capacity of 1.00 million gallons per day. Under the U.S. Clean Water Act, municipal wastewater treatment plants of this scale are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permitting program. The Texas Commission on Environmental Quality (TCEQ) oversees NPDES permits in the state, ensuring compliance with effluent limits that protect water quality. The treated effluent from Airport WWTP 3 is discharged into local waterways that ultimately drain into the Gulf of Mexico. The Galveston Bay estuary, a critical habitat for fish, shellfish, and migratory birds, is the primary downstream receiving environment. The plant's operations are subject to regulations that aim to minimize nutrient loading and other pollutants that could impact this sensitive coastal ecosystem.

The plant discharges into the Galveston Bay watershed, which flows into the Gulf of Mexico. Galveston Bay is a large estuary that supports diverse aquatic life, including commercial and recreational fisheries. The bay's health is influenced by nutrient inputs from wastewater, making treatment standards important for preventing eutrophication and maintaining water quality in this ecologically sensitive coastal region.
