Moctezuma Wastewater Treatment Plant, San Luis Potosí, Mexico

Moctezuma is a wastewater treatment plant located in the town of Moctezuma, San Luis Potosí, Mexico. It serves a population of approximately 6,458 people, classifying it as a small-scale municipal facility. The plant is situated inland, more than 10 km from the coast, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard level required by Mexican law (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. Its designed capacity is 950.40 cubic meters per day, and it discharges a similar volume, indicating full utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a river or stream within the San Luis Potosí basin, which ultimately drains into the Gulf of Mexico via the Pánuco River system. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this semi-arid region.

The plant discharges into a local watercourse within the San Luis Potosí region, part of the Pánuco River basin that flows into the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional water supply. The semi-arid climate makes water quality management critical for both ecological health and human use.
