El Dorado is a municipal wastewater treatment plant located in Eldorado, a town in the municipality of Culiacán, Sinaloa, Mexico. The facility serves a population of approximately 17,341 people, placing it in the medium-agglomeration category for Mexican wastewater infrastructure. As a plant in Mexico, El Dorado is subject to the country's federal water quality standards, including NOM-001-SEMARNAT-1996, which sets maximum permissible limits for pollutants in wastewater discharges. The plant's discharge ultimately reaches the Pacific Ocean via local waterways in the Sinaloa coastal plain. This region supports important estuarine and mangrove ecosystems that provide critical habitat for fish, crustaceans, and migratory birds. Proper wastewater treatment is essential to protect these sensitive coastal environments from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Sinaloa river system, which flows into the Pacific Ocean near the Gulf of California. This coastal zone supports diverse aquatic life, including mangrove forests and estuaries that serve as nurseries for commercially important fish species. The region's semi-arid climate means that water resources are limited, making effective wastewater treatment crucial for maintaining downstream water quality and ecosystem health.
