Tetelilla de Islas Wastewater Treatment Plant, Puebla, Mexico

Tetelilla de Islas wastewater treatment plant is located in the town of Tetelilla de Islas, within the municipality of Tuzamapan de Galeana, Puebla, Mexico. The plant serves a population of approximately 2,008 residents, reflecting a small-scale municipal facility typical of rural communities in the region. The plant provides secondary treatment, which is the standard biological treatment process required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. The facility has a designed capacity of 190.08 cubic meters per day and discharges a similar volume, indicating it operates at near-full capacity. As a secondary treatment plant, it effectively reduces organic matter and suspended solids before discharge. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Tecolutla River basin. The plant plays a crucial role in protecting downstream aquatic ecosystems and preventing waterborne diseases in the community. Its operation supports local water quality and public health in the region.

The plant discharges into the Tecolutla River basin, which flows through the state of Puebla and Veracruz before emptying into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and domestic use. The secondary treatment helps reduce nutrient loading and organic pollution, protecting downstream ecosystems and coastal waters.
