Ojocaliente Wastewater Treatment Plant, Aguascalientes, Mexico

Ojocaliente wastewater treatment plant is located in the town of Ojocaliente, within the municipality of Calvillo, Aguascalientes, Mexico. The facility serves a population of around 11,865 residents, making it a medium-sized municipal plant in the region. The plant is situated inland, more than 50 km from the coast, and its treated effluent is discharged into local water bodies. As a Mexican wastewater treatment facility, Ojocaliente is subject to the national water quality standards established by the Comisión Nacional del Agua (CONAGUA) and the Ley de Aguas Nacionales. For plants serving populations of this scale, secondary treatment is typically required to meet discharge limits for biochemical oxygen demand and total suspended solids. The plant's design and operation align with these regulatory expectations, ensuring compliance with environmental norms. The treated wastewater from Ojocaliente ultimately drains into the local hydrological network, which is part of the larger Lerma-Santiago-Pacifico basin. This basin supports agricultural activities and provides water for communities downstream. Proper treatment at Ojocaliente helps protect the water quality of receiving streams and contributes to the ecological health of the region.

The plant discharges into local watercourses that flow into the Lerma-Santiago-Pacifico basin, one of Mexico's most important hydrological systems. This basin supports diverse aquatic life and provides irrigation for agriculture in the arid Aguascalientes region. Effective wastewater treatment is crucial to prevent nutrient loading and maintain water quality for downstream communities and ecosystems.
