Overview
Calpulalpan wastewater treatment plant serves Jilotepec de Molina Enriquez in Estado de Mexico, Mexico. It provides secondary treatment for a population of 913 with a designed capacity of 86.40 cubic meters per day.
The Calpulalpan wastewater treatment plant is located in Jilotepec de Molina Enriquez, within the Estado de Mexico region of central Mexico. It serves a small community of 913 people, reflecting its role in local sanitation infrastructure for a rural or peri-urban area. The plant operates with secondary treatment, which is the standard biological treatment level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. Its designed capacity of 86.40 cubic meters per day matches the reported discharge volume, indicating consistent operation at full capacity. As a small-scale facility, it likely uses conventional activated sludge or lagoon-based processes typical for communities of this size. The treated effluent is discharged into local water bodies that ultimately drain into the Lerma River basin, which flows westward into Lake Chapala, Mexico's largest freshwater lake. This watershed supports agricultural irrigation and provides habitat for native fish species. Proper treatment is essential to prevent nutrient loading and protect downstream water quality in this ecologically sensitive region.
Environmental context
The plant's treated effluent enters the Lerma River basin, which drains into Lake Chapala, a critical freshwater resource for central Mexico. The lake supports diverse aquatic life, including endemic fish species, and provides water for irrigation and human consumption. Secondary treatment helps reduce organic pollutants and suspended solids, mitigating eutrophication risks in this downstream ecosystem.
