Francisco Murguía Wastewater Treatment Plant, General Francisco Murguía, Durango, Mexico

The Francisco Murguía wastewater treatment plant is located in General Francisco Murguía, within the state of Durango, Mexico. It serves a small community of 639 residents, reflecting its role in managing local domestic wastewater in a rural or semi-urban setting. The plant is situated inland, more than 10 km from the coast, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. With a designed capacity of 259.20 cubic meters per day and an actual discharge volume of 60.48 cubic meters per day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. As a small-scale plant in Mexico, it is subject to NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is discharged into a local water body, likely a stream or arroyo that drains into the broader hydrological network of the Nazas River basin. This basin ultimately flows into the Laguna de Mayrán, an endorheic lagoon in the Chihuahuan Desert. The plant's operation helps protect local water quality and supports the ecological health of this arid region's limited surface waters.

The plant discharges into a local watercourse that is part of the Nazas River basin, which drains into the Laguna de Mayrán, an endorheic lagoon in the Chihuahuan Desert. This region is ecologically sensitive due to its arid climate and limited water resources, making the treatment plant important for maintaining water quality and supporting downstream aquatic life and migratory birds.
