Ejido La Flor Wastewater Treatment Plant, Sinaloa, Mexico

Ejido La Flor wastewater treatment plant is located in the town of Ejido La Flor, within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of 1,095 and operates with secondary treatment, a standard level for small communities in Mexico under the national water quality regulations (NOM-001-SEMARNAT). The plant has a designed capacity of 95.04 m³/day and currently discharges 103.68 m³/day, indicating it operates near its capacity. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the basic requirements for discharge into receiving waters. The plant's proximity to the coast (within 10 km) means its treated effluent likely drains into the Pacific Ocean via local streams or the nearby Culiacán River system. This coastal discharge requires careful management to protect marine ecosystems, including estuaries and coastal lagoons that support diverse aquatic life and fisheries in the region.

The plant discharges into the Pacific coastal watershed of Sinaloa, likely via the Culiacán River or adjacent coastal lagoons. These waters support important mangrove ecosystems and serve as nursery habitats for shrimp and fish species. The proximity to the coast increases the risk of nutrient loading and pathogen contamination if treatment is inadequate, potentially affecting marine biodiversity and local fishing communities.
