Zacualpan de Amilpas Wastewater Treatment Plant, Morelos, Mexico

The Zacualpan de Amilpas wastewater treatment plant serves the small community of Zacualpan de Amilpas in the state of Morelos, Mexico. With a population served of 1,123, this facility is designed for a capacity of 1,296 cubic meters per day, though current discharge volume is 106.27 cubic meters. The plant provides secondary treatment, which is appropriate for small agglomerations under Mexican water quality regulations (NOM-001-SEMARNAT). As a secondary treatment facility, the plant reduces organic matter and suspended solids before discharging treated water. The plant operates under Mexico's federal water pollution control framework, which sets discharge limits based on receiving water body type. For small communities like Zacualpan de Amilpas, secondary treatment is the standard requirement to protect local water resources. The plant discharges into local waterways that ultimately drain into the Balsas River basin, one of Mexico's major hydrological regions. The Balsas River flows southwest through Morelos and Guerrero before emptying into the Pacific Ocean. The plant's operations help protect downstream aquatic ecosystems and water quality in this important basin.

The plant discharges into the Balsas River basin, which drains through the states of Morelos and Guerrero to the Pacific Ocean. This region supports diverse freshwater habitats and is important for local agriculture and biodiversity. The secondary treatment process helps reduce nutrient and organic pollution loads, protecting downstream water quality in a basin that faces pressures from agricultural runoff and urban development.
