Overview
La Congoja I is a secondary wastewater treatment plant serving 91 people in La Congoja, Aguascalientes, Mexico. It discharges 8.64 cubic meters of treated water daily.
La Congoja I is a municipal wastewater treatment facility located in the community of La Congoja, within the municipality of San José de Gracia, Aguascalientes, Mexico. The plant serves a small population of 91 residents, reflecting its role in a rural or peri-urban setting. Its location in the semi-arid highlands of central Mexico places it within a region where water resources are carefully managed. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. Secondary treatment is appropriate for the small population served. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater discharges must meet quality standards for receiving water bodies, and plants of this scale are typically subject to state-level oversight. The treated effluent is discharged into local watercourses that eventually drain into the Rio Grande de Santiago basin, which flows westward to the Pacific Ocean. This watershed supports agricultural activities and provides water for downstream communities. The plant's operation helps protect local water quality and reduces the risk of contamination in the region's limited surface water resources.
Environmental context
The plant discharges into the Rio Grande de Santiago basin, which drains into the Pacific Ocean via the Santiago River. This watershed is ecologically important for sustaining agriculture and biodiversity in the semi-arid Aguascalientes region. The treated effluent contributes to maintaining base flows in local streams, supporting aquatic life and downstream water users.
