Overview
Calimaya de Díaz González wastewater treatment plant serves approximately 13,709 people in Estado de México, Mexico. The facility discharges treated effluent into local water bodies within the Lerma River basin.
The Calimaya de Díaz González wastewater treatment plant is located in the municipality of Calimaya, Estado de México, Mexico. It serves an estimated population of 13,709 residents, classifying it as a medium-sized agglomeration under Mexican wastewater regulations. The plant is situated inland, approximately 50 kilometers from the Pacific coast, and its operations are part of the regional sanitation infrastructure for the Toluca Valley. Under Mexican environmental law (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants serving populations of this scale are required to meet specific discharge standards for organic matter and suspended solids. The plant is expected to provide at least secondary treatment to comply with federal regulations. The population served suggests a moderate-scale operation. The treated effluent from the plant ultimately drains into the Lerma River basin, which flows westward into Lake Chapala, Mexico's largest freshwater lake. The Lerma River is a critical water resource for agriculture and urban supply in central Mexico, and its ecological health is vital for sustaining aquatic biodiversity and downstream communities. The plant's discharge contributes to the overall water quality management in this sensitive watershed.
Environmental context
The plant discharges into the Lerma River basin, which flows into Lake Chapala, a vital freshwater ecosystem supporting diverse aquatic life and providing water for millions of people. The Lerma River is heavily impacted by agricultural runoff and urban wastewater, making treatment plants like Calimaya de Díaz González crucial for reducing nutrient loads and protecting downstream water quality. The region's volcanic terrain and seasonal rainfall patterns influence runoff and dilution capacity.
