Huitziltepec Wastewater Treatment Plant, Guerrero, Mexico

The Huitziltepec wastewater treatment plant is located in the municipality of Eduardo Neri, Guerrero, Mexico, serving a population of 2,738. The facility provides secondary treatment, a standard level for communities of this size under Mexican water quality regulations (NOM-001-SEMARNAT). The plant treats an average of 259.20 m³ of wastewater per day, operating well below its designed capacity of 777.60 m³/day. This suggests the facility has room to accommodate future population growth or increased flows. As a secondary treatment plant, it removes organic matter and suspended solids before discharge. The treated effluent is discharged into a local watercourse that ultimately drains into the Balsas River basin, one of Mexico's major hydrological systems. The Balsas River flows westward to the Pacific Ocean, supporting diverse aquatic life and agricultural activities along its course. The plant's operation helps protect downstream water quality in this ecologically important region.

The plant discharges into a tributary of the Balsas River, which flows through Guerrero and Michoacán before reaching the Pacific Ocean. The Balsas basin supports a variety of freshwater species and provides water for irrigation. Secondary treatment reduces organic pollutants, helping to maintain the ecological health of the river and its downstream environments.
