PTAR Coapantla Wastewater Treatment Plant, Coapantla, Hidalgo, Mexico

PTAR Coapantla is a municipal wastewater treatment facility located in Coapantla, within the municipality of Huautla, Hidalgo, Mexico. The plant serves a small population of 913 residents, providing essential sanitation services for this rural community. The plant operates with secondary treatment, which is appropriate for its scale and typical for small agglomerations in Mexico. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required to meet discharge standards for organic matter and suspended solids. The plant has a designed capacity of 86.40 cubic meters per day, matching the current discharge volume. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Pánuco River system. This watershed supports diverse aquatic life and is important for regional agriculture and fisheries. Proper treatment at PTAR Coapantla helps protect downstream water quality and ecosystem health.

The plant discharges into local streams that are part of the Pánuco River basin, which flows into the Gulf of Mexico. This watershed supports a variety of aquatic species and provides water for irrigation and domestic use in the region. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the ecological balance of the receiving waters and prevent eutrophication downstream.
