Chacala Wastewater Treatment Plant - Durango, Mexico

The Chacala wastewater treatment plant is located in the town of Chacala, within the municipality of Tamazula, Durango, Mexico. This facility serves a small population of 415 residents, reflecting its role in a rural or semi-urban community. The plant operates under Mexico's national water regulations, which require treatment standards for municipal wastewater. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids. With a designed capacity of 131.33 cubic meters per day and an average discharge volume of 69.12 cubic meters per day, the facility operates below its capacity, indicating room for future growth. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into local water bodies, likely tributaries of the Pacific slope rivers in Durango. The region's watershed ultimately drains toward the Pacific Ocean, supporting ecosystems that depend on clean water. Proper treatment helps protect downstream aquatic life and water quality in this semi-arid region of Mexico.

The plant discharges into local streams that are part of the Pacific slope watershed in Durango. These water bodies flow through mountainous terrain before reaching the Pacific Ocean. The region supports diverse aquatic habitats, including species adapted to seasonal flows. Effective wastewater treatment is crucial to prevent nutrient loading and maintain ecological balance in downstream rivers and coastal areas.
