Teotlalco Wastewater Treatment Plant | Puebla, Mexico

The Teotlalco wastewater treatment plant is located in the municipality of Teotlalco, in the state of Puebla, Mexico. It serves a small community of approximately 2,547 residents, providing essential sanitation services for the local population. The plant is situated inland, away from coastal areas, and its operations are part of Mexico's national wastewater management infrastructure. The plant operates with secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 241.06 volume units and a discharge volume matching that figure, the facility appears to be operating at full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is typically required for discharges into rivers and streams to meet water quality standards. The treated effluent from the plant is discharged into local water bodies, likely contributing to the hydrological network of the region. Puebla's water systems ultimately drain into the Gulf of Mexico via rivers such as the Atoyac or the Balsas basin. The plant plays a role in protecting downstream water quality and aquatic ecosystems in the region.

The plant discharges into local watercourses that are part of the Balsas River basin, which flows into the Pacific Ocean. The region's aquatic ecosystems support diverse species, and the plant's secondary treatment helps reduce organic pollution loads, protecting water quality for downstream communities and habitats. The area is characterized by seasonal rainfall and agricultural activity, making effective wastewater treatment important for maintaining ecological balance.
