Gleneagles WWTP - Advanced Wastewater Treatment in Harris County, Texas

Gleneagles WWTP is an advanced wastewater treatment facility located in Harris County, Texas, serving a population of 1,220. The plant operates as part of the municipal wastewater infrastructure for the greater Houston metropolitan area, which is one of the fastest-growing regions in the United States. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 1,135.62 million gallons per year and an actual discharge volume of 541.31 million gallons per year, the facility operates below its design capacity. As a US-based plant, it 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), which set effluent limits to protect water quality. The treated effluent from Gleneagles WWTP ultimately flows into the San Jacinto River basin, which drains into Galveston Bay and the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading to these sensitive coastal waters, supporting aquatic life and recreational uses in the bay ecosystem.

The plant discharges within the San Jacinto River watershed, which flows southeast into Galveston Bay, a major estuary on the Texas Gulf Coast. Galveston Bay supports diverse aquatic life, including oyster reefs, shrimp, and finfish, and is an important migratory corridor for birds. Advanced treatment at this plant helps minimize nutrient pollution that can contribute to algal blooms and hypoxia in the bay.
