Overview
Villa Hidalgo wastewater treatment plant in Sonora, Mexico, serves 1,525 people with secondary treatment. It discharges 268.70 cubic meters of treated wastewater daily, with a designed capacity of 179.71 cubic meters.
Villa Hidalgo is a wastewater treatment plant located in the town of Villa Hidalgo, Sonora, Mexico. It serves a population of 1,525 residents, making it a small-scale municipal facility. The plant is situated in the arid northwestern region of Mexico, near the Sierra Madre Occidental foothills. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. It has a designed capacity of 179.71 cubic meters per day and currently treats a daily flow of 268.70 cubic meters, indicating operation above its nominal capacity. Under Mexican regulations (NOM-001-SEMARNAT), secondary treatment is required for discharges to rivers and streams to meet water quality standards. The treated effluent is discharged into local watercourses that eventually drain into the Gulf of California. The region's water resources are critical for agriculture and ecosystems in the Sonoran Desert. Proper wastewater treatment helps protect downstream water quality and supports the ecological health of the Gulf of California watershed.
Environmental context
The plant discharges into local arroyos that feed the Yaqui River basin, which flows into the Gulf of California. This coastal marine environment supports diverse aquatic life, including fish and migratory birds. The Sonoran Desert region faces water scarcity, making treated wastewater reuse important for sustaining local ecosystems and agricultural needs.
