Pueblo Mayo Wastewater Treatment Plant, Sonora, Mexico

Pueblo Mayo is a wastewater treatment plant located in the town of Pueblo Mayo, within the municipality of Navojoa, Sonora, Mexico. The facility serves a population of approximately 2,784 residents, making it a small-scale municipal treatment plant in a rural or semi-urban setting. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. Secondary treatment typically involves aerobic biological processes such as activated sludge or trickling filters. The plant has a designed capacity of 1,228.61 cubic meters per day and currently discharges 263.52 cubic meters per day, indicating it operates well below its capacity. The treated effluent is discharged into the local environment, likely into a nearby watercourse or arroyo that eventually drains into the Gulf of California. The plant plays a crucial role in protecting local water quality and public health in the Mayo River basin, an important agricultural region in southern Sonora.

The plant is located inland in the Sonora region, within the Mayo River watershed. Treated wastewater likely flows into the Mayo River, which drains into the Gulf of California, a biologically productive marine environment. The region supports diverse aquatic life and is important for local fisheries and agriculture. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems.
