Loma Prieta Wastewater Treatment Plant, San Luis Potosí, Mexico

Loma Prieta is a wastewater treatment plant located in the historic center of San Luis Potosí, Mexico, within the state of San Luis Potosí. The plant serves a small population of 228 people, reflecting its role in a localized area of the city. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 65.66 units and a current discharge volume of 21.60 units, the plant operates below its capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent from Loma Prieta is discharged into the local watershed, which ultimately drains into the Gulf of Mexico via the Pánuco River system. The plant plays a role in protecting the region's water resources and downstream ecosystems.

The plant discharges into the San Luis Potosí Valley, part of the Pánuco River basin, which flows eastward to the Gulf of Mexico. The downstream environment supports diverse aquatic life and is important for regional water supply. The plant's secondary treatment helps reduce organic pollution, protecting the ecological health of the river system.
