Ayotetla Wastewater Treatment Plant, Acoxcatlán, Hidalgo, Mexico

Ayotetla is a wastewater treatment plant located in Acoxcatlán, within the municipality of Lolotla, Hidalgo, Mexico. It serves a population of 3,651, classifying it as a small-scale facility under Mexican wastewater regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater before discharge into water bodies. The plant operates with a designed capacity of 345.60 cubic meters per day and a discharge volume of 345.60 cubic meters per day, indicating full utilization. As a secondary treatment facility, it meets the basic requirements of Mexico's NOM-001-SEMARNAT-1996 standard, which sets maximum permissible limits for pollutants in wastewater discharges. The plant's location in a rural, inland area suggests it serves a small community with limited industrial influence. The treated effluent is likely discharged into a local watercourse that drains into the Pánuco River basin, eventually reaching the Gulf of Mexico. The plant plays a crucial role in protecting local water quality and downstream ecosystems, including the diverse aquatic life in the Pánuco River system.

The plant discharges into a local stream that is part of the Pánuco River basin, one of Mexico's major river systems. The Pánuco River flows into the Gulf of Mexico, supporting important coastal wetlands and fisheries. The region's mountainous terrain and seasonal rainfall patterns influence runoff and water availability. Protecting this watershed is essential for maintaining water quality for downstream communities and preserving aquatic habitats, including those for migratory fish species.
