Coatepec Wastewater Treatment Plant, Puebla, Mexico

The Coatepec wastewater treatment plant is located in the town of Coatepec, in the state of Puebla, Mexico. It serves a small population of approximately 1,004 residents, reflecting its role as a local municipal facility for a rural community. The plant is situated on Avenida 16 de Septiembre and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. It has a designed capacity of 95.04 cubic meters per day, matching the current discharge volume, indicating full utilization. As a small-scale facility, it aligns with typical infrastructure for communities of this size in Mexico, where secondary treatment is common for municipal wastewater. The treated effluent is discharged into local water bodies that ultimately drain into the Gulf of Mexico via the Tecolutla River basin. The region's aquatic ecosystems benefit from the plant's pollution reduction, supporting freshwater biodiversity and downstream water quality. Proper operation helps protect the ecological health of the surrounding watershed.

The plant discharges into the Tecolutla River basin, which flows eastward to the Gulf of Mexico. This coastal watershed supports diverse aquatic life, including fish and invertebrates, and is important for local fisheries. The secondary treatment reduces organic load and suspended solids, mitigating eutrophication risks in downstream estuaries.
