Dallas Salmon Central WWTP - League City, Texas Wastewater Treatment

Dallas Salmon Central WWTP is a municipal wastewater treatment facility located in League City, Galveston County, Texas. The plant serves a population of approximately 45,461 residents, placing it in the medium-sized agglomeration category for U.S. wastewater infrastructure. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Texas Commission on Environmental Quality (TCEQ). For a plant of this scale, secondary treatment is typically required, with possible additional nutrient removal if discharging to sensitive waters. The plant's treated effluent ultimately drains into the Galveston Bay system, a major estuary on the Texas Gulf Coast. This watershed supports diverse aquatic life, including commercial fisheries and migratory bird populations, and is ecologically sensitive to nutrient loading and pollutant discharges.

The plant's discharge enters the Galveston Bay watershed, which flows into the Gulf of Mexico. Galveston Bay is a large estuary that supports critical habitats for fish, shellfish, and migratory birds. The bay is subject to nutrient pollution concerns, making treatment standards important for protecting downstream water quality and marine ecosystems.
