Pánuco de Coronado Wastewater Treatment Plant, Durango, Mexico

The Pánuco de Coronado wastewater treatment plant is located in the city of Pánuco de Coronado, in the state of Durango, Mexico. It serves a population of approximately 1,387 residents, making it a small-scale municipal facility. The plant is situated in an inland area, far from coastal zones, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. Its designed capacity is 311.04 cubic meters per day, and it currently discharges 131.33 cubic meters per day, indicating it operates below its full capacity. As a small agglomeration, it falls under Mexico's water quality standards for wastewater discharge. The treated effluent is discharged into local water bodies, likely contributing to the regional hydrological system. The plant plays a key role in protecting local water resources and public health in the semi-arid region of Durango. Its operation supports the sustainability of the surrounding environment and downstream ecosystems.

The plant discharges treated wastewater into local streams or arroyos that eventually drain into the Nazas River basin, a vital water source for the region. The Nazas River flows into the Laguna de Mayran, an important wetland area that supports diverse aquatic life and migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting the ecological health of these downstream water bodies.
