La Mesita de Cuajari La Mesita is a municipal wastewater treatment facility located in La Mesita del Cuajari, a small community in the municipality of Sahuaripa, Sonora, Mexico. The plant serves a population of 119 residents, reflecting its role in a rural setting. It is situated inland, more than 10 km from the coast, and operates within the arid climate of northern Mexico. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 63.07 m³/day and an actual discharge volume of 11.23 m³/day, the facility operates well below its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges into national waters, ensuring compliance with national water quality standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Yaqui River basin, a major hydrological system in Sonora. This river flows into the Gulf of California, supporting diverse aquatic life and agricultural activities downstream. The plant's operation helps protect water quality in this ecologically sensitive region.
Environmental context
The plant discharges into the Yaqui River basin, which flows through Sonora and into the Gulf of California. This watershed supports a variety of aquatic species and is important for irrigation and local ecosystems. The arid climate means water resources are scarce, making effective wastewater treatment critical for maintaining water quality and ecological balance in the region.
