Overview
Cortazar Dren Merino is a wastewater treatment plant in Cortazar, Guanajuato, Mexico, serving approximately 37,550 people. It has a designed capacity of 1.00 unit and operates under Mexico's national water regulations.
Cortazar Dren Merino is a wastewater treatment plant located in Cortazar, Guanajuato, Mexico. The facility serves an estimated population of 37,550, placing it in the medium agglomeration category for Mexican wastewater infrastructure. The plant is situated inland, more than 50 km from the coast, and its operations are governed by Mexico's federal water laws, including the National Water Law and regulations from CONAGUA (Comisión Nacional del Agua). As a medium-sized plant, Cortazar Dren Merino is expected to meet secondary treatment standards under Mexican regulations, which align with general international norms for municipal wastewater treatment. The facility likely employs conventional treatment technologies common in the region, such as activated sludge or stabilization ponds. The plant discharges treated wastewater into local water bodies that ultimately drain into the Lerma River basin, a major hydrological system in central Mexico. The Lerma River flows westward into Lake Chapala, Mexico's largest freshwater lake, which supports diverse aquatic life and provides water for irrigation and human consumption. Protecting this watershed is critical for maintaining water quality in the Lerma-Chapala basin, a region facing pressures from agricultural runoff and industrial activities.
Environmental context
The plant's treated effluent enters the Lerma River basin, which flows into Lake Chapala, the largest freshwater lake in Mexico. This watershed supports a rich ecosystem, including endemic fish species and migratory birds. Downstream, the Lerma River continues to the Pacific Ocean via the Santiago River. The region faces challenges from agricultural and industrial pollution, making effective wastewater treatment essential for preserving water quality and aquatic biodiversity.
