Proper treatment helps preserve water quality in this ecologically important watershed.

The plant discharges into the Lerma River basin, which flows into Lake Chapala, a critical freshwater resource for the region. The watershed supports diverse aquatic life and provides water for agriculture and human consumption. Effective wastewater treatment is essential to prevent nutrient pollution and maintain the ecological health of this downstream environment.
