San Andres Jalmolongo 2 Wastewater Treatment Plant, Malinalco, Mexico

San Andres Jalmolongo 2 is a wastewater treatment plant located in Malinalco, within the Estado de México region of Mexico. It serves a small community of 438 people, reflecting its role in managing domestic wastewater for a rural or semi-urban area. The plant is situated inland, away from coastal zones, and operates under Mexico's national water quality regulations. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 345.60 m³/day and a current discharge volume of 41.47 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. As a small-scale plant, it aligns with Mexico's standards for wastewater treatment in smaller agglomerations. The treated effluent is discharged into a local water body, contributing to the protection of the surrounding watershed. The plant's operation supports the ecological health of the region, which is part of the Balsas River basin, ultimately draining into the Pacific Ocean. Proper treatment helps safeguard downstream aquatic ecosystems and water quality for communities and agriculture.

The plant discharges into a local water body within the Balsas River basin, which flows through central Mexico and empties into the Pacific Ocean. This watershed supports diverse aquatic life and provides water for irrigation and human use. Secondary treatment reduces organic pollutants, helping to maintain water quality in downstream rivers and reservoirs, which are ecologically sensitive areas.
