San Pedro Ecatepec 2 Wastewater Treatment Plant, Tlaxcala, Mexico

San Pedro Ecatepec 2 is a municipal wastewater treatment plant located in San Pedro Ecatepec, a community in the state of Tlaxcala, Mexico. The plant serves a population of 1,763 people, classifying it as a small-scale facility within the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. It has a designed capacity of 432.00 cubic meters per day and currently treats 216.00 cubic meters per day, indicating it operates at about 50% of its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges into national waters, ensuring compliance with national water quality standards. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Pánuco River basin. The plant plays a crucial role in protecting downstream aquatic ecosystems and maintaining water quality in the region's rivers and streams.

The plant discharges into the local watershed, which is part of the Pánuco River basin. This basin drains into the Gulf of Mexico, supporting diverse aquatic life and providing water for agriculture and communities. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the ecological health of the receiving waters and prevent eutrophication in downstream environments.
