Uvalde WWTP: Wastewater Treatment Facility in Uvalde, Texas

Uvalde WWTP is a municipal wastewater treatment facility located in Uvalde, Texas, serving a population of about 15,672. The plant is situated on County Road 106 in Uvalde County, within the state's semi-arid climate region. As a U.S. facility serving a medium-sized agglomeration, Uvalde WWTP is subject to the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permitting program. This regulatory framework mandates secondary treatment for municipal wastewater, ensuring that effluent meets water quality standards before discharge. The plant's design and operation align with these federal requirements, which are enforced by the Texas Commission on Environmental Quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Nueces River basin. The Nueces River flows southeast through Texas and empties into the Gulf of Mexico at Nueces Bay. This river system supports diverse aquatic life and provides water for agricultural and municipal uses downstream.

Uvalde WWTP discharges into the Nueces River basin, which flows through south-central Texas to the Gulf of Mexico. The Nueces River and its tributaries support a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. The river's flow is critical for maintaining estuarine health in Nueces Bay, a productive nursery for shrimp and crabs. The plant's effluent must meet state water quality standards to protect these downstream ecosystems.
