AnAhuac Wastewater Treatment Plant, Colonia Anáhuac, Durango, Mexico

AnAhuac is a municipal wastewater treatment plant located in Colonia Anáhuac, within the municipality of Canatlán, Durango, Mexico. It serves a small population of 876 residents, reflecting its role in a rural or peri-urban community. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharge into water bodies. It has a designed capacity of 184.90 m³/day and currently discharges 170.21 m³/day, indicating near-capacity operation. The treated effluent is likely discharged into a local watercourse that drains into the San Pedro River basin, ultimately flowing into the Pacific Ocean via the Nazas River system. This watershed supports agricultural activities and local ecosystems, making proper treatment essential for water quality and public health.

The plant discharges into a local watercourse that is part of the San Pedro River basin, which flows into the Nazas River and eventually reaches the Pacific Ocean. The region's semi-arid climate means water resources are limited, and the receiving waters support agricultural irrigation and local biodiversity. Proper secondary treatment helps protect downstream water quality and aquatic life.
