Overview
La Sauceda wastewater treatment plant serves 18,702 people in Hermosillo, Sonora, Mexico. It operates under Mexico's national water regulations for municipal wastewater treatment.
La Sauceda is a municipal wastewater treatment plant located in the Modelo neighborhood of Hermosillo, the capital city of Sonora, Mexico. The plant serves a population of approximately 18,702 residents, placing it in the small-to-medium agglomeration category for Mexican wastewater infrastructure. Under Mexico's federal water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996 standards, plants of this scale are required to meet specific discharge limits for organic matter and solids. Typical plants in this region employ secondary treatment systems such as activated sludge or stabilization ponds to comply with national standards. The plant discharges treated effluent into the local watershed, which ultimately drains into the Gulf of California via the Sonora River basin. This coastal region supports diverse marine and estuarine ecosystems, making proper wastewater treatment critical for protecting downstream water quality and aquatic life.
Environmental context
The plant's treated effluent flows into the Sonora River basin, which drains into the Gulf of California, a biologically rich sea that supports fisheries, migratory birds, and marine mammals. The region's arid climate means water resources are scarce, and maintaining water quality in the river system is essential for both ecological health and human use downstream.
