Guadalupe Victoria Wastewater Treatment Plant, Sinaloa, Mexico

The Guadalupe Victoria wastewater treatment plant is located in the town of Guadalupe Victoria (El Atorón), within the municipality of Culiacán, Sinaloa, Mexico. It serves a population of approximately 3,976 residents, classifying it as a small-scale municipal facility. The plant is situated near the Pacific coast, less than 10 kilometers inland. The plant employs secondary treatment processes, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 596.16 m³/day and an actual discharge volume of 587.52 m³/day, the facility operates near its full capacity. As a small agglomeration, it meets the national treatment standards for organic matter and suspended solids removal. The treated effluent is discharged into local watercourses that ultimately drain into the Pacific Ocean, likely via the Culiacán River basin or adjacent coastal lagoons. The proximity to the coast means the plant's discharge can affect nearshore marine ecosystems, including estuaries and mangrove habitats that support diverse aquatic life and fisheries in the region.

The plant discharges into the Pacific coastal watershed of Sinaloa, with the receiving waters eventually reaching the Gulf of California. The region supports important mangrove ecosystems and estuarine habitats that serve as nursery grounds for shrimp and fish species. The plant's secondary treatment helps reduce organic pollution loads to these sensitive coastal environments.
