Overview
El Rincon wastewater treatment plant in Durango, Mexico, serves a small population of 183 with secondary treatment. It discharges 17.28 cubic meters of treated wastewater daily.
El Rincon is a municipal wastewater treatment plant located in the rural community of El Rincón, within the municipality of Tepehuanes, Durango, Mexico. The plant serves a small population of 183 residents, reflecting its role in a sparsely populated area. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids. The plant has a designed capacity of 172.80 cubic meters per day and currently discharges 17.28 cubic meters daily, indicating low utilization. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. For small rural plants like El Rincon, secondary treatment is typical to meet basic environmental standards. The treated effluent is likely discharged into a local watercourse that drains into the San Pedro River basin, part of the larger Nazas-Aguanaval system. This region is semi-arid, and water resources are critical for agriculture and local ecosystems. The plant helps protect downstream water quality in a watershed that supports diverse aquatic life and seasonal wetlands.
Environmental context
The plant's discharge likely enters a tributary of the San Pedro River, which flows into the Nazas River basin in northern Mexico. This watershed is ecologically important for maintaining water availability in a semi-arid region, supporting riparian habitats and migratory birds. Downstream, the Nazas River eventually reaches the Laguna de Mayran, a seasonal lake that provides critical wetland habitat.
