Colonia General Felipe Angeles Wastewater Treatment Plant, Durango, Mexico

Colonia General Felipe Angeles is a wastewater treatment plant located in the community of Felipe Angeles, within Praxedis G. Guerrero Nuevo, in the municipality of Durango, Durango, Mexico. The plant serves a population of approximately 1,369 residents, reflecting its role in managing domestic wastewater for a small community in northern Mexico. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 138.24 cubic meters per day and an actual discharge volume of 129.60 cubic meters per day, the facility operates near its design capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent is discharged into the local environment, likely contributing to the Nazas River basin, which flows through Durango and eventually into the Laguna de Mayran, an important wetland ecosystem. The plant's operation helps protect local water quality and supports the ecological health of the region's water bodies.

The plant discharges into the Nazas River basin, which flows through the arid landscape of Durango and feeds into the Laguna de Mayran, a vital wetland that supports diverse aquatic bird species and serves as a critical stopover for migratory birds. The region's semi-arid climate makes water resources particularly sensitive to pollution, and the plant's secondary treatment helps mitigate impacts on downstream ecosystems.
