Campo El Seis Wastewater Treatment Plant, Culiacán, Sinaloa

Campo El Seis is a municipal wastewater treatment plant located in Culiacán, the capital city of Sinaloa state in northwestern Mexico. The plant serves a small population of 1,278 residents, reflecting its role in a smaller community within the broader Culiacán metropolitan area. The facility operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 129.60 m³/day and a current discharge volume of 120.96 m³/day, the plant operates near its design capacity, indicating consistent utilization. The treated effluent from Campo El Seis ultimately reaches the Pacific Ocean, as the plant is situated within 10 km of the coast. The receiving water body is likely a local drainage channel or estuary that flows into the Gulf of California. This coastal discharge requires careful management to protect marine ecosystems and comply with Mexican environmental standards.

The plant discharges into the Pacific coastal watershed of Sinaloa, with effluent likely flowing through local arroyos or drainage systems to the Gulf of California. This region supports diverse marine life, including important fisheries and migratory species. The proximity to the coast necessitates effective treatment to prevent nutrient loading and protect coastal water quality.
