Miguel Negrete Wastewater Treatment Plant, Durango, Mexico

Miguel Negrete is a wastewater treatment plant located in the town of Miguel Negrete, within the municipality of Nuevo Ideal, Durango, Mexico. The plant serves a population of 1,074 and is part of the municipal wastewater infrastructure for this rural community. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 164.16 m³/day and an average discharge volume of 138.24 m³/day, the plant operates at approximately 84% capacity, indicating consistent utilization. The treated effluent is discharged into a local watercourse that ultimately drains into the Pacific Ocean via the Nazas River basin. The plant plays a key role in protecting downstream water quality in the semi-arid region of Durango, where water resources are scarce and sensitive to pollution.

The plant discharges into a tributary of the Nazas River, which flows through the arid landscapes of Durango and Coahuila before reaching the Laguna District and eventually the Pacific Ocean. The Nazas River basin is ecologically important for irrigation and supports diverse aquatic life in a region where water is a critical resource. Proper wastewater treatment helps prevent nutrient loading and pathogen contamination in this sensitive watershed.
