Overview
Ciudad Lerdo wastewater treatment plant serves over 164,000 people in Durango, Mexico. It operates under Mexican water quality regulations (NOM-001-SEMARNAT-1996) for discharge into the Nazas River basin.
Ciudad Lerdo wastewater treatment plant is located in Ciudad Lerdo, Durango, Mexico, serving a population of approximately 164,291. The plant is part of the municipal wastewater infrastructure for the city, situated in the Comarca Lagunera region, an important agricultural and industrial area in northern Mexico. As a large agglomeration serving over 150,000 people, the plant is expected to provide secondary treatment or higher under Mexican regulations (NOM-001-SEMARNAT-1996), which sets discharge limits for pollutants into national waters. Typical facilities of this scale in Mexico employ activated sludge or lagoon systems to meet regulatory standards. The plant discharges treated wastewater into the Nazas River basin, which flows into the Laguna de Mayran, a shallow lake system that is part of the endorheic basin of the Bolson de Mapimi. This region supports agricultural irrigation and provides habitat for migratory birds. Proper treatment is critical to protect water quality in this arid region where water resources are scarce.
Environmental context
The plant discharges into the Nazas River basin, which drains into the Laguna de Mayran, a seasonal lake in the endorheic Bolson de Mapimi basin. This watershed supports irrigated agriculture and provides critical habitat for waterfowl and migratory birds in the Chihuahuan Desert ecoregion. Effective wastewater treatment is essential to prevent nutrient loading and maintain water quality in this water-scarce region.
