El Portento is a municipal wastewater treatment plant located in El Potento, a locality in the state of Durango, Mexico. The plant serves a small population of 86 residents, reflecting its role in a rural or small community setting. It is situated inland, more than 10 km from the coast, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 129.60 m³/day and an average discharge volume of 101.09 m³/day, the facility operates below its full capacity. As a small-scale plant, it is subject to Mexican official standards (NOM-001-SEMARNAT) that set discharge limits for pollutants into national waters. The treated effluent is discharged into local water bodies that eventually drain into the Nazas River basin, part of the endorheic Bolsón de Mapimí region. This watershed supports arid-adapted ecosystems and is important for local agriculture and wildlife. The plant's operation helps protect downstream water quality in this sensitive dryland environment.
Environmental context
The plant discharges into the Nazas River basin, which flows into the endorheic Bolsón de Mapimí, a closed basin with no outlet to the sea. This arid region supports unique desert ecosystems and is a critical water source for local communities and agriculture. Protecting water quality in this basin is essential for maintaining ecological balance and human use.
