Halls Bayou WWTP - Projected Wastewater Treatment Plant in League City, Texas

Halls Bayou WWTP is a planned wastewater treatment facility located in League City, Texas, within Galveston County. The plant is designed to serve a population of 15,000, positioning it as a medium-sized municipal facility for the region. As a projected plant, it is not yet operational but represents future infrastructure development to meet growing wastewater treatment needs. The plant will be subject to the US Clean Water Act and will require an NPDES permit issued by the Texas Commission on Environmental Quality (TCEQ). For a facility of this scale, secondary treatment is typically mandated, with potential additional requirements for nutrient removal if discharging into sensitive waters. The designed capacity is 1.00 million gallons per day, though treatment process details are not yet finalized. The treated effluent will likely discharge into a local waterway within the Galveston Bay watershed, ultimately flowing into the Gulf of Mexico. This region supports diverse aquatic life and is an important estuarine ecosystem. The plant's operation will help protect water quality in the bay and downstream coastal environments.

The plant will discharge into a tributary of Galveston Bay, a major estuary on the Texas Gulf Coast. Galveston Bay supports diverse aquatic life, including fish, shellfish, and migratory birds, and is an important nursery habitat. The bay ultimately drains into the Gulf of Mexico, a large marine ecosystem. Protecting water quality in this watershed is critical for maintaining ecological health and supporting local fisheries and recreation.
