Charapan Wastewater Treatment Plant, Michoacán, Mexico

The Charapan wastewater treatment plant is located in the town of Charapan, Michoacán, Mexico. It serves a population of approximately 3,651 residents, classifying it as a small-scale municipal facility. The plant operates with secondary treatment, which is appropriate for communities of this size under Mexican wastewater regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 691.20 cubic meters per day and currently discharges 345.60 cubic meters per day, indicating it operates at about half its capacity. This suggests room for future growth or seasonal variations in flow. The treated effluent is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Balsas River basin. The region's watershed supports diverse aquatic life and agricultural activities downstream. Proper treatment helps protect these ecosystems from nutrient pollution and pathogens.

The plant's discharge enters the local drainage network within the Balsas River basin, which flows southwestward to the Pacific Ocean. This watershed supports agricultural irrigation and freshwater habitats. Effective secondary treatment reduces organic load and pathogens, safeguarding downstream water quality for both ecological and human uses.
