Estancia de Mosqueira Wastewater Treatment Plant, Aguascalientes, Mexico

Estancia de Mosqueira wastewater treatment plant is located in the town of Estancia de Mosqueira, within the municipality of Rincón de Romos, Aguascalientes, Mexico. The plant serves a population of approximately 3,468 residents, classifying it as a small-scale municipal facility. It is situated in an inland area, far from coastal zones, and its operations are integral to local sanitation infrastructure. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the Official Mexican Standard NOM-001-SEMARNAT-1996. With a designed capacity of 86.40 cubic meters per day and a current discharge volume of 328.32 cubic meters per day, the facility operates at a high utilization rate. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, contributing to the protection of the surrounding environment. The plant plays a key role in maintaining water quality in the Aguascalientes region, which is part of the Lerma-Santiago-Pacific hydrological basin. Proper wastewater management helps safeguard downstream ecosystems and supports agricultural and domestic water uses in the area.

The plant discharges treated wastewater into local streams that eventually flow into the Lerma River, a major watercourse in central Mexico. The Lerma River drains into Lake Chapala, Mexico's largest freshwater lake, and ultimately reaches the Pacific Ocean via the Santiago River. The region's semi-arid climate makes water resources particularly sensitive to pollution, and the plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies.
