Bacoachi Fosa Wastewater Treatment Plant, Bacoachi, Sonora, Mexico

Bacoachi Fosa is a municipal wastewater treatment facility located in Bacoachi, Sonora, Mexico. The plant serves a small population of 584 residents, providing secondary treatment to manage domestic wastewater from the community. Its location in the arid Sonoran Desert region underscores the importance of efficient water reuse and environmental protection. The plant operates with a designed capacity of 66.53 cubic meters per day and currently treats 55.30 cubic meters daily, indicating it is operating below its full capacity. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids, meeting typical standards for small communities in Mexico under the national water regulations (NOM-001-SEMARNAT). The treated effluent is discharged into the local environment, contributing to the sustainability of water resources in the Sonora River basin. The plant plays a vital role in protecting downstream water quality and supporting the ecological health of the region's arid watersheds.

Bacoachi Fosa discharges treated wastewater into the Sonora River basin, which flows through the Sonoran Desert and ultimately drains into the Gulf of California. The region's arid climate makes water resources scarce, and the plant's effluent supports local streamflow and groundwater recharge. The downstream environment includes sensitive desert riparian habitats that rely on consistent water quality for native flora and fauna.
