Canutillo Wastewater Treatment Plant, Durango, Mexico

The Canutillo wastewater treatment plant is located in the town of Canutillo, within the municipality of Ocampo, Durango, Mexico. It serves a population of 913 residents, making it a small-scale facility focused on local wastewater management. The plant is situated in an inland area, far from coastal zones, and its operations are part of Mexico's national water infrastructure. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates). With a designed capacity of 155.52 m³/day and an actual discharge volume of 86.40 m³/day, the facility operates below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, likely contributing to the hydrological network of the region. The plant plays a key role in protecting downstream water quality, as untreated wastewater could impact local rivers and groundwater. Given its small population served and inland location, the environmental risk is low, but continued compliance with discharge standards is essential for safeguarding the local watershed.

The Canutillo treatment plant discharges into local watercourses that eventually drain into the Nazas River basin, a major hydrological system in northern Mexico. This basin supports agricultural activities and provides water for communities in Durango and Coahuila. The region's semi-arid climate makes water quality management critical for maintaining ecosystem health and water availability. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream aquatic life and preventing eutrophication in receiving waters.
