Ejido Francisco Villa Wastewater Treatment Plant, Culiacán, Sinaloa, Mexico

Ejido Francisco Villa is a wastewater treatment plant located in Ejido Francisco Villa, Culiacán, Sinaloa, Mexico. It serves a population of 2,099 and operates with secondary treatment, discharging a volume of 198.72 units. The plant is situated near the Pacific coast, within 10 km of the shoreline. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater before discharge. Its designed capacity matches the discharge volume, indicating full utilization. As a coastal facility, it must meet stringent effluent standards to protect marine ecosystems. The treated effluent likely discharges into a local watercourse that flows into the Pacific Ocean, contributing to the coastal watershed of Sinaloa. The region supports diverse marine life and is important for fisheries and tourism. Proper treatment helps mitigate nutrient loading and pathogen risks in coastal waters.

The plant discharges into a local drainage system that ultimately reaches the Pacific Ocean near the coast of Sinaloa. This coastal area supports ecologically sensitive habitats, including mangroves and estuaries, which provide nursery grounds for fish and migratory birds. Nutrient and pathogen control from the plant is critical to prevent eutrophication and protect water quality in the receiving marine environment.
