Unidad Habitacional Campo Militar NUm 1 Wastewater Treatment Plant, Naucalpan de Juárez

Unidad Habitacional Campo Militar NUm 1 is a wastewater treatment plant located in Naucalpan de Juárez, within the Estado de México, Mexico. The plant serves a population of approximately 7,300 residents, providing secondary treatment to manage domestic wastewater from the area. The plant operates with a designed capacity of 2,592.00 m³/day and currently treats a discharge volume of 691.20 m³/day. As a secondary treatment facility, it meets the standard requirements for municipal wastewater treatment in Mexico, which aligns with national regulations under the Ley de Aguas Nacionales and NOM-001-SEMARNAT standards for discharge quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Río de la Compañía and then into the Río Lerma, a major river system that flows into Lake Chapala, Mexico's largest freshwater lake. The plant plays a key role in protecting the Río Lerma basin from untreated sewage, supporting downstream aquatic ecosystems and water quality.

The plant discharges into the Río de la Compañía, a tributary of the Río Lerma, which flows into Lake Chapala. This watershed supports diverse aquatic life and provides water for irrigation and human consumption. The secondary treatment helps reduce organic pollutants and suspended solids, mitigating eutrophication risks in Lake Chapala, an ecologically sensitive water body.
