Gabriel Hernández Wastewater Treatment Plant, Durango, Mexico

The Gabriel Hernández wastewater treatment plant is located in the town of Gabriel Hernández, within the municipality of Nombre de Dios, Durango, Mexico. This facility serves a small population of 913 residents, providing essential sanitation services for the local community. The plant employs secondary treatment, which is appropriate for small agglomerations under Mexican water quality regulations (NOM-001-SEMARNAT). With a designed capacity of 639.36 m³/day and an actual discharge volume of 86.40 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Nazas River basin. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region's arid environment.

The plant discharges into the Nazas River basin, which flows through the arid landscapes of Durango and eventually reaches the Pacific Ocean via the Laguna de Mayrán. This watershed supports limited but ecologically important riparian habitats in a semi-desert region, where water quality is critical for both human use and biodiversity.
