Lago de Texcoco II Ingeniero Ramon Grijalva Ruiz Wastewater Treatment Plant, Chimalhuacán

Lago de Texcoco II Ingeniero Ramon Grijalva Ruiz is a large wastewater treatment plant located in Chimalhuacán, Estado de México, Mexico. It serves a population of approximately 365,090, classifying it as a major municipal facility within the Mexico City metropolitan area. The plant plays a critical role in managing wastewater from this densely populated region. As a large agglomeration, the plant is expected to meet stringent treatment standards under Mexican environmental regulations (NOM-001-SEMARNAT). Facilities of this scale typically employ secondary or advanced treatment to reduce pollutants before discharge. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating substantial infrastructure. The plant's effluent ultimately drains into the closed basin of the Valley of Mexico, a historically significant watershed that once contained Lake Texcoco. Today, the region's water bodies are highly managed, and the plant's operations are vital for protecting local water quality and preventing pollution in the surrounding urban and agricultural areas. The treated water supports downstream ecosystems and helps mitigate environmental degradation in this sensitive basin.

The plant discharges into the closed basin of the Valley of Mexico, a historically lacustrine region that once held Lake Texcoco. This basin has no natural outlet, making water quality management critical. The treated effluent supports local water bodies and irrigation channels, influencing the ecological health of the surrounding area, which includes wetlands and agricultural zones that provide habitat for migratory birds and other wildlife.
