Donna WWTP - Progreso, Texas Wastewater Treatment Plant

Donna WWTP is a municipal wastewater treatment facility located in Progreso, Hidalgo County, Texas. The plant serves a population of around 15,790 residents in the Progreso area, contributing to the region's wastewater management infrastructure. As a U.S. facility, Donna WWTP operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. For a plant serving this population size, secondary treatment is typically required to meet effluent standards, ensuring the removal of organic matter and suspended solids before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Rio Grande and then to the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in the Rio Grande basin and the sensitive coastal ecosystems of the Gulf.

The treated effluent from Donna WWTP flows into the Rio Grande, a major river that forms the border between the U.S. and Mexico. The Rio Grande empties into the Gulf of Mexico, supporting diverse aquatic life and providing critical habitat for migratory birds. The plant's operations help maintain water quality in this ecologically significant river system, which faces pressures from agricultural runoff and urban development.
