Molino Granjas Wastewater Treatment Plant, Naucalpan de Juárez, Estado de México

Molino Granjas is a wastewater treatment plant located in Naucalpan de Juárez, Estado de México, Mexico. It serves a population of approximately 22,818 people, classifying it as a medium-sized agglomeration under Mexican regulatory frameworks. The plant is situated in the metropolitan area of Mexico City, a densely populated urban region with significant industrial activity. As a facility in Mexico, Molino Granjas is subject to the country's national wastewater standards, which are enforced by the National Water Commission (CONAGUA). For agglomerations of this scale, secondary treatment is typically required to meet discharge limits for organic matter and suspended solids. The regulatory framework ensures compliance with environmental norms. The treated effluent from Molino Granjas likely discharges into local water bodies that are part of the Pánuco River basin, which ultimately flows into the Gulf of Mexico. The plant plays a role in protecting downstream ecosystems and water quality in the region, particularly in the context of urban runoff and industrial discharges common in the Mexico City metropolitan area.

The plant's discharge likely enters the local drainage network within the Pánuco River basin, which flows eastward to the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agricultural and municipal use downstream. The region's high population density and industrial activity place pressure on water quality, making effective wastewater treatment critical for maintaining ecological balance and preventing eutrophication in receiving waters.
