San Pedro Huaquilpan Wastewater Treatment Plant, Acayuca, Hidalgo, Mexico

San Pedro Huaquilpan is a wastewater treatment plant located in Acayuca, within the municipality of Zapotlán de Juárez, Hidalgo, Mexico. The plant serves a population of approximately 5,476 residents, making it a small-scale facility in the region. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. The designed capacity is 1,036.80 cubic meters per day, with an actual discharge volume of 518.40 cubic meters per day, indicating the plant is operating below its full capacity. The treated effluent is discharged into local water bodies that ultimately drain into the Gulf of Mexico via the Pánuco River basin. The plant plays a crucial role in protecting downstream ecosystems and water quality in this hydrologically important region.

The plant's discharge contributes to the local watershed, which is part of the Pánuco River basin. This basin drains into the Gulf of Mexico, supporting diverse aquatic life and coastal ecosystems. The region's semi-arid climate makes water quality management critical for both human use and ecological health.
