Fraccionamiento Los Agaves Wastewater Treatment Plant, Tlajomulco, Jalisco

Fraccionamiento Los Agaves is a wastewater treatment plant located in Tlajomulco, within the municipality of Tlajomulco de Zúñiga in the state of Jalisco, Mexico. The plant serves a population of around 9,127 residents, classifying it as a small to medium-sized facility in the region. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 864 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and must comply with official standards (NOM-001-SEMARNAT-1996) for discharge quality. The treated effluent is discharged into the local hydrological system, which ultimately drains into the Pacific Ocean via the Santiago River basin. The plant plays a crucial role in protecting water quality in the region, particularly given the proximity to the coast (within 50 km) and the ecological sensitivity of downstream water bodies.

The plant discharges into the Santiago River basin, which flows westward through Jalisco and empties into the Pacific Ocean near the port of San Blas. This watershed supports diverse aquatic life and is an important water resource for agriculture and urban areas. The secondary treatment provided by the plant helps reduce organic pollution and nutrient loads, mitigating eutrophication risks in downstream reservoirs and coastal zones.
