Overview
Cosío wastewater treatment plant serves the town of Cosío in Aguascalientes, Mexico. It provides essential sanitation for approximately 4,900 residents.
The Cosío wastewater treatment plant is located in the town of Cosío, within the state of Aguascalientes, Mexico. Serving a population of around 4,900 people, this facility is a key component of the local municipal wastewater infrastructure, ensuring that domestic sewage is properly managed before discharge. As a small-scale treatment plant in Mexico, it operates under the national regulatory framework established by the Comisión Nacional del Agua (CONAGUA), which sets standards for wastewater treatment and discharge. For communities of this size, secondary treatment is typically required to reduce organic pollutants and suspended solids, protecting both public health and the environment. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Río San Pedro, part of the larger Lerma-Chapala basin. This watershed supports agricultural activities and provides water for nearby communities. Proper treatment at Cosío helps maintain water quality in this semi-arid region, where water resources are particularly valuable.
Environmental context
The plant's discharge flows into the Río San Pedro, a tributary of the Lerma River, which ultimately reaches Lake Chapala, Mexico's largest freshwater lake. This watershed is ecologically significant, supporting diverse aquatic life and providing irrigation for agriculture in the region. Effective wastewater treatment is crucial to prevent nutrient loading and protect the lake's ecosystem.
