La Purisima San Rafael y La Luz is a wastewater treatment plant located in the Ejido La Purisima area of Doctor Mora, Guanajuato, Mexico. The facility serves a small population of 1,278 residents and operates with a designed capacity of 120.96 cubic meters per day, matching its current discharge volume. The plant provides primary treatment, which involves physical processes such as sedimentation to remove suspended solids. Under Mexican regulations (NOM-001-SEMARNAT-1996), primary treatment is permitted for small communities, though secondary treatment is increasingly recommended to meet water quality standards for discharge into water bodies. The treated effluent is discharged into local watercourses that eventually drain into the Lerma River basin, a major hydrological system in central Mexico. The Lerma River flows into Lake Chapala, Mexico's largest freshwater lake, which supports diverse aquatic life and provides water for irrigation and human consumption. Protecting this watershed is critical for regional water security.
Environmental context
The plant discharges into the Lerma River basin, which flows into Lake Chapala, the largest freshwater lake in Mexico. This watershed supports a variety of aquatic species and provides water for agriculture and drinking water for millions of people. The region's semi-arid climate makes water quality management essential to prevent eutrophication and maintain ecological balance.
