Porfirio Parra Barreales y Juarez y Reforma Wastewater Treatment Plant, Doctor Porfirio Parra, Chihuahua

Porfirio Parra Barreales y Juarez y Reforma is a municipal wastewater treatment plant located in Doctor Porfirio Parra, within the municipality of Guadalupe, Chihuahua, Mexico. The plant serves a small community of approximately 1,705 residents, reflecting its role in managing domestic wastewater for this rural area. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. With a designed capacity of 1,235.52 cubic meters per day and a current discharge volume of 604.80 cubic meters per day, the plant operates below its full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Rio Bravo (Rio Grande) basin, a critical water source for both Mexico and the United States. The Rio Bravo flows into the Gulf of Mexico, supporting diverse aquatic ecosystems and agricultural communities along its course. Proper treatment helps protect downstream water quality and public health.

The plant discharges into the Rio Bravo (Rio Grande) basin, which flows through the arid Chihuahuan Desert before reaching the Gulf of Mexico. This river system supports critical habitats for migratory birds and endemic fish species. The region's semi-arid climate means water resources are scarce, making effective wastewater treatment essential for maintaining water quality and ecosystem health in the downstream environment.
