Overview
El Chabacano wastewater treatment plant in Durango, Mexico, serves 265 people with secondary treatment. It discharges 25.06 m³/day and has a designed capacity of 46.66 m³/day.
El Chabacano is a wastewater treatment plant located in the rural community of El Chabacano, within the municipality of San Juan del Río, Durango, Mexico. The plant serves a small population of 265 residents, reflecting its role in providing essential sanitation services to a dispersed rural area. The plant operates with secondary treatment, which is the standard biological treatment process required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 46.66 m³/day and an average discharge volume of 25.06 m³/day, the facility operates well within its capacity, indicating adequate infrastructure for the current population. The treated effluent is discharged into local water bodies that ultimately drain into the Nazas River basin, a critical water source for the arid region of Durango. The Nazas River flows into the Laguna de Mayrán, an endorheic basin that supports agricultural irrigation and local ecosystems. Proper treatment helps protect these water resources from nutrient pollution and pathogens.
Environmental context
The plant's discharge enters local streams that feed into the Nazas River, which flows through the semi-arid Durango landscape. The Nazas River is a vital water source for agriculture and supports riparian habitats in a region with limited surface water. Downstream, the river terminates in the Laguna de Mayrán, an important wetland area that provides habitat for migratory birds and endemic species. Effective secondary treatment is crucial to prevent eutrophication and maintain water quality in this sensitive endorheic basin.
