Conjunto Habitacional Sedena Colonia Santiago Occipaco Wastewater Treatment Plant, Naucalpan de Juárez

Conjunto Habitacional Sedena Colonia Santiago Occipaco is a wastewater treatment plant located in Naucalpan de Juárez, within the Estado de México, Mexico. The plant serves a population of 1,825 and is situated in a residential area of the Mexico City metropolitan region. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater before discharge. Its designed capacity is 172.80 m³/day, and the reported discharge volume matches this capacity, indicating full utilization. The plant operates as part of the local water infrastructure managed by municipal authorities. The treated effluent is discharged into the local drainage system, which ultimately flows into the Río de los Remedios and then into the Lake Texcoco system, a historically significant water body in the Valley of Mexico. This watershed supports urban and ecological functions, and the plant's secondary treatment helps reduce pollutant loads to the receiving environment.

The plant discharges into the Río de los Remedios, a tributary of the Lake Texcoco system in the Valley of Mexico. Lake Texcoco is an ecologically important but highly altered water body that provides habitat for migratory birds and supports regional hydrology. The surrounding watershed is densely urbanized, making effective wastewater treatment critical to preventing eutrophication and protecting downstream aquatic life.
