Overview
San Juan del Río wastewater treatment plant serves 4,336 people in Durango, Mexico. The facility operates under Mexican water quality regulations for inland discharge.
The San Juan del Río wastewater treatment plant is located in San Juan del Río del Centauro del Norte, Durango, Mexico. It serves a population of approximately 4,336 residents, classifying it as a small-scale municipal facility. The plant is situated inland, far from coastal areas, and its operations are subject to Mexican environmental standards. As a small agglomeration, the plant is expected to meet secondary treatment standards under Mexican regulations (NOM-001-SEMARNAT), which set limits for pollutants in wastewater discharges. Typical plants of this size employ biological treatment systems such as activated sludge or lagoons to comply with discharge norms. The treated effluent is discharged into local water bodies within the Durango region, ultimately contributing to the hydrological basin that drains into the Pacific Ocean via the Nazas River system. The plant plays a role in protecting downstream water quality and supporting local ecosystems.
Environmental context
The plant discharges into the Nazas River basin, which flows through the arid landscapes of Durango and eventually reaches the Laguna de Mayran and the Pacific Ocean. This watershed supports limited but ecologically important aquatic life, including species adapted to seasonal flows. Protecting water quality in this basin is critical for maintaining regional biodiversity and agricultural water supplies.
