San Miguel Tateposco Wastewater Treatment Plant, San Estéban, Jalisco

San Miguel Tateposco is a municipal wastewater treatment plant located in the Los Mezquites area of San Estéban, within the municipality of Zapopan in Jalisco, Mexico. The plant serves a small community of approximately 3,651 residents, reflecting its role in managing domestic wastewater for this suburban locality near Guadalajara. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharges into water bodies. Its designed capacity matches the current discharge volume of 345.60 cubic meters per day, indicating full utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Santiago River basin, which flows westward through Jalisco and into the Pacific Ocean. The Santiago River is a major hydrological feature in the region, supporting agriculture and ecosystems downstream. The plant's operation helps protect local water quality in the context of the surrounding urban and industrial landscape.
