Ciudad Universitaria FCPS Wastewater Treatment Plant, Coyoacán, Mexico City

Ciudad Universitaria FCPS is a wastewater treatment plant located in the Coyoacán borough of Mexico City, Mexico. It serves a population of 2,738 people and operates as part of the city's municipal wastewater infrastructure. The plant provides secondary treatment, a standard level for small to medium agglomerations. With a designed capacity of 648.00 m³/day and an actual discharge volume of 259.20 m³/day, it operates well below its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for discharges into national waters to meet quality standards. The treated effluent is discharged into the local drainage system, which ultimately flows into the Valley of Mexico basin. This basin is a closed hydrological system, meaning water does not naturally drain to the sea. The plant plays a role in protecting local water bodies and groundwater from untreated sewage, supporting the ecological health of the region.

The plant discharges into the Valley of Mexico basin, a closed basin with no natural outlet to the sea. This basin includes Lake Texcoco and other remnant water bodies, which are ecologically sensitive and support migratory birds and aquatic life. The treated effluent helps reduce pollution loads in the basin, protecting local ecosystems and groundwater quality.
