Paredes y San Antonio de Los Ríos Wastewater Treatment Plant, Aguascalientes, Mexico

Paredes y San Antonio de Los Ríos wastewater treatment plant is located in San Antonio de los Ríos, within the municipality of San José de Gracia, Aguascalientes, Mexico. The plant serves a small population of 925 residents, providing essential wastewater treatment for this rural community. It is situated inland, far from coastal areas, and its operations are part of the local water infrastructure managed under Mexican environmental regulations. The plant employs secondary treatment, a standard biological process that removes organic matter and suspended solids. It has a designed capacity of 518.40 cubic meters per day and currently treats 425.95 cubic meters daily, indicating it operates below its full capacity. As a small-scale facility in Mexico, it is subject to the country's federal water pollution control standards, which mandate treatment levels appropriate for the receiving environment. The treated effluent is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Rio Grande de Santiago basin. The surrounding region is semi-arid, and the plant plays a key role in protecting local streams and groundwater from contamination. Its operation supports the ecological health of the Aguascalientes watershed, which is important for agriculture and biodiversity.

The plant discharges treated wastewater into local waterways that are part of the Rio Grande de Santiago basin, which flows westward to the Pacific Ocean. This semi-arid region relies on careful water management to sustain aquatic habitats and agricultural activities. The plant's secondary treatment helps reduce nutrient and organic pollution, supporting the ecological balance of downstream water bodies.
