Club de Golf Chiluca II Wastewater Treatment Plant, Ciudad López Mateos, Estado de México

Club de Golf Chiluca II is a wastewater treatment plant located in Ciudad López Mateos, within the municipality of Atizapán de Zaragoza, Estado de México, Mexico. The plant serves a population of approximately 15,160 people, placing it in the small-to-medium agglomeration category for Mexican wastewater infrastructure. As a plant in Mexico, it is subject to the country's federal water quality standards, including NOM-001-SEMARNAT-1996, which sets limits for pollutants in treated wastewater discharged into national waters. The plant's treated effluent likely discharges into a local watercourse that drains into the Río de la Compañía or another tributary of the Río Moctezuma, eventually reaching the Pánuco River and the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agricultural and urban uses downstream.

The plant is located inland in the Valley of Mexico, a high-altitude basin. Its treated wastewater likely flows into the Río de la Compañía, a tributary of the Río Moctezuma, which joins the Pánuco River before emptying into the Gulf of Mexico. This watershed is ecologically important, supporting riparian habitats and providing water for irrigation and industry in the region.
