Overview
Lomita de Paso Blanco is a secondary wastewater treatment plant serving Jesús Gómez Portugal (Margaritas), Aguascalientes, Mexico. It treats wastewater for over 10,000 residents with a discharge volume of 971.14 thousand cubic meters annually.
Lomita de Paso Blanco is a municipal wastewater treatment plant located in the community of Paso Blanco, within the municipality of Jesús María, Aguascalientes, Mexico. It serves the nearby town of Jesús Gómez Portugal (Margaritas) and surrounding areas, providing secondary treatment for a population of approximately 10,259 residents. The plant discharges treated wastewater at a volume of 971.14 thousand cubic meters per year. The plant operates under Mexico's national water regulations, which require secondary treatment for urban wastewater before discharge. With a designed capacity of 8,640 thousand cubic meters per year, the plant's current discharge volume indicates utilization at about 11% of capacity, suggesting ample room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting standards set by the National Water Commission (CONAGUA). The treated effluent from Lomita de Paso Blanco is discharged into local watercourses that eventually drain into the Aguascalientes Valley basin, part of the Lerma-Santiago-Pacific hydrological region. This region supports agricultural activities and provides water for downstream communities. The plant plays a key role in protecting local water quality and preventing pollution of rivers and groundwater in the semi-arid climate of central Mexico.
Environmental context
The plant's discharge contributes to the Aguascalientes Valley watershed, which is part of the larger Lerma-Santiago-Pacific basin. This region is characterized by semi-arid conditions and intensive agriculture, making water quality management critical. The treated effluent supports downstream ecosystems and irrigation, but secondary treatment may not fully remove nutrients, posing risks of eutrophication in receiving water bodies. The plant helps mitigate pollution from urban runoff and domestic wastewater, protecting aquatic life and human water uses in the area.
