El Refugio de Los Sauces is a wastewater treatment plant located in Silao de la Victoria, Guanajuato, Mexico. It serves a population of 1,296 people, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant provides primary treatment, which involves physical processes like sedimentation to remove solids. With a designed capacity and discharge volume of 122.69 cubic meters per day, it operates at full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), primary treatment is the minimum required for municipal wastewater, though larger plants often incorporate secondary or tertiary stages. The treated effluent is discharged into local water bodies that drain into the Lerma River basin, eventually reaching the Pacific Ocean. The plant plays a role in protecting the region's water quality, particularly in an area with agricultural and industrial activity.
Environmental context
The plant discharges into the Lerma River basin, which flows into Lake Chapala, Mexico's largest freshwater lake, and then to the Pacific Ocean via the Rio Grande de Santiago. The watershed supports diverse aquatic life and is important for irrigation and drinking water. Primary treatment reduces suspended solids but may not fully remove nutrients, posing risks of eutrophication downstream.
