Bacadehuachi Wastewater Treatment Plant, Bacadéhuachi, Sonora, Mexico

The Bacadehuachi wastewater treatment plant is located in the town of Bacadéhuachi, Sonora, Mexico, serving a population of approximately 1,240 residents. The facility provides secondary treatment, a standard level for small communities in Mexico, ensuring that wastewater is treated before being released into the environment. With a designed capacity of 249.70 cubic meters per day and an average discharge volume of 278.21 cubic meters per day, the plant operates under Mexico's national water regulations, which mandate treatment standards for municipal wastewater. As a secondary treatment plant, it removes organic matter and suspended solids, reducing pollution loads in the receiving water bodies. The plant's treated effluent is discharged into local streams that eventually drain into the Yaqui River basin, an important hydrological system in Sonora. The Yaqui River flows into the Gulf of California, supporting diverse aquatic life and agricultural activities downstream. Proper treatment at Bacadehuachi helps protect these water resources from contamination.

The Bacadehuachi plant discharges into local waterways that are part of the Yaqui River basin, which flows through the Sonoran Desert and into the Gulf of California. This basin supports a variety of fish species and provides water for irrigation in the region. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in downstream water bodies and protecting the ecological health of the Gulf of California.
