Overview
CIA Mexicana de Aguas wastewater treatment plant serves Cuautitlán Izcalli, Estado de México, Mexico. It treats wastewater from approximately 146,000 people, supporting the local water infrastructure.
CIA Mexicana de Aguas is a wastewater treatment plant located in Cuautitlán Izcalli, Estado de México, Mexico. The facility serves a population of approximately 146,000, making it a medium-to-large agglomeration within the region. It plays a key role in managing municipal wastewater for this suburban area northwest of Mexico City. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants must meet discharge standards based on the receiving water body. For plants of this scale, secondary treatment is typically required to reduce organic matter and suspended solids. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial treatment capability. The treated effluent is discharged into the local watershed, which ultimately drains into the Río Moctezuma and then the Pánuco River system, flowing into the Gulf of Mexico. This river basin supports diverse aquatic life and is important for regional water supply and agriculture. Proper treatment helps protect downstream ecosystems and communities from pollution.
Environmental context
The plant discharges into the Río Moctezuma basin, part of the larger Pánuco River system that drains into the Gulf of Mexico. This watershed supports a variety of freshwater species and provides water for irrigation and domestic use. The region's semi-arid climate makes water quality management critical for maintaining ecological balance and human health. Downstream areas include wetlands and estuaries that are sensitive to nutrient loading and contaminants.
