Huachinera Wastewater Treatment Plant - Sonora, Mexico

Huachinera wastewater treatment plant is located in the town of Huachinera, in the state of Sonora, Mexico. The facility serves a population of approximately 1,071 residents, providing secondary treatment to municipal wastewater. As a small-scale plant, it plays a key role in managing local sanitation needs. The plant operates with a designed capacity of 116.64 cubic meters per day and currently discharges 319.68 cubic meters of treated wastewater. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is the standard for municipal wastewater, ensuring that effluent meets quality criteria for discharge into receiving waters. The treated effluent is released into local waterways that eventually drain into the Gulf of California. This contributes to protecting downstream ecosystems, including sensitive coastal habitats. The plant's operation helps reduce pollution loads in the region's arid environment, where water resources are scarce.

The plant discharges into local streams that flow through the Sonoran Desert, eventually reaching the Gulf of California. This watershed supports diverse aquatic life and is an important migratory corridor for birds. The arid climate makes water quality management critical for sustaining both human and ecological needs.
