Overview
La Florida wastewater treatment plant in Ejido Tierra y Libertad Número Dos, Sinaloa, Mexico, serves a small population of 1,095 with secondary treatment. It discharges 103.68 thousand cubic meters annually.
La Florida is a wastewater treatment plant located in the rural community of Ejido Tierra y Libertad Número Dos, within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a small population of approximately 1,095 people, reflecting its role in a sparsely populated agricultural area. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants before discharge. The plant has a designed capacity of 107.14 thousand cubic meters per year and currently treats 103.68 thousand cubic meters annually, indicating near-full utilization. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater, with effluent quality limits for BOD, TSS, and other parameters. The treated effluent is discharged into local watercourses that ultimately drain into the Pacific Ocean via the Culiacán River basin. Sinaloa's coastal wetlands and estuaries are ecologically important for migratory birds and aquatic species. The plant's secondary treatment helps protect these downstream ecosystems from excessive nutrient loading and organic pollution.
Environmental context
The plant discharges into the Culiacán River basin, which flows westward through the state of Sinaloa and empties into the Pacific Ocean near the city of Culiacán. The lower river and its delta support diverse aquatic life, including fish and crustaceans important for local fisheries. The coastal zone is part of a larger wetland system that provides critical habitat for migratory waterfowl along the Pacific Flyway. Secondary treatment reduces the risk of eutrophication and oxygen depletion in these sensitive waters.
