Felipe Carrillo Puerto Wastewater Treatment Plant, Tlaxcala, Mexico

The Felipe Carrillo Puerto wastewater treatment plant is located in the municipality of Atltzayanca, Tlaxcala, Mexico. It serves a small population of 1,269 residents, providing secondary treatment to municipal wastewater. The plant has a designed capacity of 120.96 cubic meters per day and currently discharges 120.10 cubic meters daily. As a secondary treatment facility, the plant meets the standard level of treatment required for small agglomerations in Mexico under the national water regulations (NOM-001-SEMARNAT-1996). These regulations set discharge limits for conventional pollutants to protect receiving water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that drain into the Gulf of Mexico via the Panuco River basin. The region's hydrology supports agricultural and ecological systems, and the plant's discharge contributes to maintaining water quality in downstream environments. Proper treatment helps protect aquatic life and downstream communities.

The plant discharges into local streams that are part of the Panuco River basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is important for regional agriculture. The secondary treatment provided helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream water bodies.
