General Francisco Villa Wastewater Treatment Plant, Nombre de Dios, Durango, Mexico

The General Francisco Villa wastewater treatment plant is located in Nombre de Dios, Durango, Mexico. It serves a small community of 128 people, reflecting its role as a local municipal facility in a rural or semi-urban setting. The plant operates under Mexico's national water regulations, which mandate treatment standards for discharges into the environment. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity is 13.82 units, with an actual discharge volume of 12.10 units, indicating near-capacity operation. As a small-scale facility, it is subject to Mexican official standards (NOM-001-SEMARNAT) that set pollutant limits for wastewater discharges. The treated effluent is discharged into local water bodies, likely tributaries of the San Pedro River or other streams in the Nazas-Aguanaval basin. This region is part of the endorheic basin of the Bolson de Mapimi, where water resources are critical for agriculture and ecosystems. Proper treatment helps protect downstream water quality and supports the arid region's limited freshwater resources.

The plant discharges into local streams that eventually drain into the Nazas-Aguanaval basin, an endorheic system in northern Mexico. This basin supports irrigated agriculture and seasonal wetlands, making water quality management essential. The region's arid climate means surface water is scarce, and treated wastewater reuse or safe discharge is vital for maintaining ecological balance and preventing contamination of groundwater.
