Irapuato II is a municipal wastewater treatment plant located in Irapuato, Guanajuato, Mexico. It serves a population of approximately 210,000, making it a significant facility for the region's wastewater management. The plant is situated in an inland area, over 50 km from the coast, and its operations are governed by Mexico's federal water laws, including the National Water Law (Ley de Aguas Nacionales) and standards set by CONAGUA (National Water Commission). For a plant of this scale, Mexican regulations typically require secondary treatment or higher to protect water quality. The plant likely employs conventional biological treatment methods common in large Mexican municipalities. The population served suggests a substantial treatment capacity. The treated effluent from Irapuato II is discharged into local water bodies within the Lerma-Santiago-Pacifico hydrological region. This region drains into the Pacific Ocean via the Lerma River and Santiago River systems. The plant plays a critical role in protecting downstream water quality, supporting agricultural irrigation, and maintaining ecological balance in the basin.
Environmental context
Irapuato II discharges into the Lerma River basin, which flows into Lake Chapala, Mexico's largest freshwater lake, and eventually reaches the Pacific Ocean via the Santiago River. The Lerma-Chapala basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and human consumption. The plant's operations help reduce nutrient and pollutant loads, mitigating eutrophication risks in Lake Chapala and downstream ecosystems.
