El Potosi is a wastewater treatment plant located in the town of El Potosi, within the municipality of Poanas, Durango, Mexico. The facility serves a small population of 730 residents, providing secondary treatment to municipal wastewater. It is situated inland, more than 10 km from the coast, and operates as part of the local water infrastructure managed by municipal authorities. The plant has a designed capacity of 86.40 m³/day and currently treats an average daily flow of 69.12 m³/day, indicating a utilization rate of approximately 80%. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), such plants must meet specific effluent quality standards for parameters like BOD, TSS, and pathogens. The treated effluent is discharged into local water bodies, likely an arroyo or seasonal stream that drains into the Nazas River basin. This region is part of the endorheic Bolsón de Mapimí basin, where water resources are scarce and sensitive to pollution. The plant plays a crucial role in protecting local groundwater and surface water quality, supporting agricultural and ecological needs in this semi-arid environment.
Environmental context
The plant discharges into local waterways that are part of the Nazas River basin, which flows into the endorheic Bolsón de Mapimí region. This area is characterized by limited surface water and high ecological sensitivity, as it supports endemic species and migratory birds. Proper wastewater treatment is essential to prevent nutrient loading and contamination of these fragile aquatic habitats.
