Santa Rosa 30 Wastewater Treatment Plant, Tlaltizapán de Zapata, Morelos

Santa Rosa 30 is a municipal wastewater treatment plant located in the town of Santa Rosa 30, within the municipality of Tlaltizapán de Zapata in the state of Morelos, Mexico. The plant serves a population of about 9,337 people, classifying it as a small to medium-sized facility in the region. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge into receiving water bodies. The designed capacity is 2,764.80 thousand cubic meters per year, and the current discharge volume is 883.87 thousand cubic meters per year, indicating operational capacity utilization. The treated effluent is discharged into local watercourses that eventually drain into the Balsas River basin, one of Mexico's major river systems. The Balsas River flows southwest to the Pacific Ocean, supporting diverse aquatic life and agricultural activities in the region. Proper treatment helps protect downstream water quality and ecosystems.

The plant discharges into the Balsas River basin, which drains into the Pacific Ocean. The Balsas River is a vital water source for agriculture and supports a variety of fish species. Effective secondary treatment reduces organic pollutants and suspended solids, mitigating eutrophication risks and protecting downstream aquatic habitats in this semi-arid region.
