Bocas Maravillas El Santuario Wastewater Treatment Plant, Bocas, San Luis Potosí

Bocas Maravillas El Santuario is a municipal wastewater treatment plant located in Bocas, a locality within the municipality of San Luis Potosí, Mexico. The plant serves a population of 2,738 people, classifying it as a small-scale facility in the region. It operates under Mexico's national water regulations, which mandate secondary treatment for urban wastewater to protect public health and the environment. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity is 475.20 m³/day, with an actual discharge volume of 259.20 m³/day, indicating operational headroom. As a small agglomeration, the plant's treatment level aligns with Mexican norms for communities of this size, ensuring compliance with federal discharge standards. The treated effluent is discharged into local watercourses that drain into the Panuco River basin, eventually reaching the Gulf of Mexico. This downstream connection highlights the plant's role in protecting both local streams and the broader coastal ecosystem from untreated sewage pollution.

The plant discharges into the Panuco River basin, which flows eastward to the Gulf of Mexico. This watershed supports diverse aquatic life and is an important resource for agriculture and communities downstream. The secondary treatment provided helps reduce nutrient and organic loads, mitigating eutrophication risks in receiving waters and preserving water quality for downstream uses.
