Overview
PorreNa is a secondary treatment plant serving 183 people in La Porreña, Chihuahua, Mexico. It discharges 17.28 m³/day of treated wastewater into local water bodies.
PorreNa is a municipal wastewater treatment plant located in La Porreña, a locality in the municipality of Allende, Chihuahua, Mexico. The plant serves a small population of 183 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 43.20 m³/day and an actual discharge volume of 17.28 m³/day, the facility operates well below its capacity. Mexican wastewater regulations (NOM-001-SEMARNAT-1996) set discharge limits for pollutants, and secondary treatment typically meets these standards for small communities. The treated effluent is discharged into local surface waters, eventually contributing to the Rio Conchos basin, which flows into the Rio Grande (Rio Bravo) and ultimately the Gulf of Mexico. The region's semi-arid climate makes water quality management important for downstream agricultural and ecological uses.
Environmental context
The plant's discharge enters the Rio Conchos watershed, a major tributary of the Rio Grande (Rio Bravo). This river system supports irrigated agriculture and provides habitat for fish and migratory birds. The semi-arid climate of Chihuahua means that maintaining water quality in the Rio Conchos is critical for both human use and the ecological health of the lower Rio Grande and its delta into the Gulf of Mexico.
