Overview
Colonia San Pedro wastewater treatment plant in San José del Río, Aguascalientes, Mexico, serves 456 people with secondary treatment and a designed capacity of 60.48 units.
Colonia San Pedro is a wastewater treatment plant located in San José del Río, within the municipality of Asientos, Aguascalientes, Mexico. The plant serves a small population of 456 residents, reflecting its role in a rural or peri-urban community. It is situated in the central highlands of Mexico, an area characterized by semi-arid climate and seasonal rainfall. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 60.48 units and a current discharge volume of 43.20 units, the plant operates below its capacity, indicating room for future growth. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is likely discharged into a local watercourse that drains into the Aguascalientes basin, eventually contributing to the Lerma-Santiago-Pacific hydrological system. This region supports agricultural activities and local ecosystems, making proper wastewater treatment essential for protecting water quality and public health.
Environmental context
The plant discharges into the Aguascalientes basin, part of the larger Lerma-Santiago-Pacific watershed. This semi-arid region relies on limited surface water for irrigation and domestic use. The treated effluent helps maintain water quality in local streams that eventually flow into the Pacific Ocean via the Santiago River. Downstream ecosystems include riparian habitats that support migratory birds and native fish species, making nutrient and pathogen removal critical.
