Mazatán Wastewater Treatment Plant, Sonora, Mexico

The Mazatán wastewater treatment plant is located in Mazatán, Sonora, Mexico, serving a population of approximately 1,287. The plant provides secondary treatment, a standard level for small communities, ensuring that wastewater is treated before being released into the environment. With a designed capacity of 224.64 cubic meters per day and a discharge volume of 307.58 cubic meters per day, the plant operates under Mexico's national water regulations, which require treatment facilities to meet quality standards for effluent discharge. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, contributing to the protection of downstream ecosystems. The plant's location in Sonora, a state with arid and semi-arid climates, makes water reuse and quality management particularly important for sustaining local water resources and agricultural activities.

The plant discharges into local watercourses that eventually drain into the Gulf of California, a biologically rich marine ecosystem. The region supports diverse aquatic life and migratory species, making proper wastewater treatment essential for maintaining water quality and ecological balance in the downstream environment.
