Overview
Tlajomulco de Zúñiga wastewater treatment plant serves approximately 146,000 people in Tlajomulco, Jalisco, Mexico. The plant is located inland and operates under Mexico's national water regulations.
The Tlajomulco de Zúñiga wastewater treatment plant is a municipal facility located in Tlajomulco, within the state of Jalisco, Mexico. Serving an estimated population of 146,036, the plant is part of the region's critical water infrastructure for the Guadalajara metropolitan area. As a large agglomeration, the plant is expected to provide at least secondary treatment under Mexican water quality standards (NOM-001-SEMARNAT). Plants of this scale in Mexico typically employ conventional activated sludge or lagoon systems to meet discharge standards. The designed capacity is reported as 1.00 (likely in cubic meters per second or similar unit), indicating a substantial facility capable of handling the region's wastewater load. The plant discharges into the local watershed, which ultimately drains into the Pacific Ocean via the Santiago River basin. The Santiago River is a major waterway in western Mexico, supporting diverse aquatic life and providing water for agricultural and industrial uses downstream. Proper treatment at this plant is essential to protect water quality in the river and its receiving waters.
Environmental context
The plant's treated effluent flows into the Santiago River basin, which drains into the Pacific Ocean near San Blas, Nayarit. The Santiago River supports a variety of freshwater species and is an important resource for irrigation and industry in Jalisco and Nayarit. Downstream ecosystems, including coastal lagoons and estuaries, rely on adequate water quality from upstream treatment facilities to maintain ecological balance and biodiversity.
