Nacori Chico Wastewater Treatment Plant, Nácori Chico, Sonora, Mexico

The Nacori Chico wastewater treatment plant is located in the town of Nácori Chico, Sonora, Mexico. It serves a population of approximately 1,397 residents, providing secondary treatment to manage municipal wastewater. The plant is situated inland, away from coastal areas, and its operations are part of the local infrastructure for water quality management. As a secondary treatment facility, Nacori Chico employs biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 134.78 cubic meters per day and currently treats a discharge volume of 153.79 cubic meters per day, indicating it operates near its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is standard for municipal plants of this scale to meet discharge standards. The treated effluent is discharged into local water bodies, likely tributaries of the Yaqui River basin, which flows into the Gulf of California. This discharge supports the ecological health of the region's arid landscape, where water resources are critical for both human use and wildlife. The plant plays a key role in preventing untreated wastewater from affecting downstream communities and ecosystems.

The plant discharges into the Yaqui River basin, which drains into the Gulf of California. This watershed supports diverse aquatic life and is important for migratory birds. The arid Sonoran environment makes water quality management crucial for sustaining local ecosystems and downstream habitats.
