Rastro Municipal Wastewater Treatment Plant, Valle de Bravo, Estado de México

Rastro Municipal is a wastewater treatment plant located in Valle de Bravo, a town in the Estado de México, Mexico. The plant serves a small community of approximately 1,068 people, reflecting its role in managing local domestic wastewater. It is situated inland, away from coastal areas, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the NOM-001-SEMARNAT-1996 standard. With a designed capacity of 259.20 m³/day and an actual discharge volume of 101.09 m³/day, the plant operates below its full capacity, indicating potential for future growth or seasonal variations in flow. The treated effluent is discharged into the local watershed, which ultimately drains into the Valle de Bravo reservoir, an important water body for the region. This reservoir supplies drinking water to Mexico City and supports recreational activities and aquatic ecosystems. The plant's operation helps protect water quality in this sensitive basin.

The plant discharges into the Valle de Bravo reservoir, part of the Cutzamala River system, which provides drinking water to Mexico City. The reservoir is ecologically significant, supporting diverse aquatic life and serving as a critical water source. Downstream, the water flows into the Balsas River basin, eventually reaching the Pacific Ocean. Protecting this watershed is essential for both human consumption and regional biodiversity.
