Overview
La Soledad wastewater treatment plant in Durango, Mexico, serves a small population of 947 with secondary treatment. It discharges 155.52 cubic meters of treated wastewater daily.
La Soledad wastewater treatment plant is located in the town of La Soledad, within the municipality of Canatlán, Durango, Mexico. The facility serves a small population of approximately 947 residents, reflecting its role in a rural or semi-urban community. The plant operates with secondary treatment, which is a standard biological process that removes organic matter and suspended solids from wastewater. Under Mexican environmental regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants are required to meet specific discharge standards based on the receiving water body. For a plant of this scale, secondary treatment is typically sufficient to comply with national norms. The plant has a designed capacity of 190.08 cubic meters per day and currently treats 155.52 cubic meters per day, indicating it operates below its full capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Pacific Ocean via the Rio Grande de Santiago and the Rio Lerma-Santiago system. The plant's operation helps protect downstream water quality and supports the ecological health of the region's rivers and reservoirs, which are important for agriculture and biodiversity in the semi-arid landscape of Durango.
Environmental context
The plant discharges into local streams that feed into the Rio Nazas and Rio Aguanaval basins, which are part of the larger Rio Grande de Santiago system draining into the Pacific Ocean. The region is semi-arid, and water resources are critical for irrigation and livestock. The plant's secondary treatment reduces organic pollution, helping to maintain water quality in downstream reservoirs and supporting aquatic life in a water-stressed environment.
