Rodeo Wastewater Treatment Plant, Durango, Mexico

Rodeo wastewater treatment plant is located in the town of Rodeo, Durango, Mexico, serving a population of about 3,468 residents. The facility provides secondary treatment, a standard level for communities of this size in Mexico, ensuring that organic pollutants and suspended solids are reduced before discharge. The plant has a designed capacity of 518.40 cubic meters per day and currently treats an average daily flow of 328.32 cubic meters, operating below its full capacity. As a municipal facility in Mexico, it is subject to national water quality standards (NOM-001-SEMARNAT-1996) that regulate pollutant levels in treated wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Rio Nazas basin. The region's semi-arid climate makes water resources particularly valuable, and proper wastewater treatment helps protect downstream ecosystems and agricultural water users.

The plant discharges into the Rio Nazas basin, a major river system in northern Mexico that flows into the Laguna de Mayran and eventually reaches the Pacific Ocean. This watershed supports agricultural irrigation and provides habitat for native fish species. In the semi-arid Durango region, treated wastewater contributes to maintaining base flows in the river, which is critical for local biodiversity and water availability.
