Key Largo Wastewater Treatment Plant | Florida Keys Coastal Facility

The Key Largo wastewater treatment plant is a municipal facility serving the community of Key Largo, Florida, in the Florida Keys. With a population served of 7,500, it is classified as a small to medium agglomeration under U.S. regulatory frameworks. The plant is situated in a coastal environment, near the Florida Keys Overseas Heritage Trail. As a U.S. wastewater facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Florida Department of Environmental Protection. For plants of this scale in sensitive coastal areas, advanced treatment is often required to protect marine ecosystems. The designed capacity of 1.00 million gallons per day indicates the plant's intended throughput. The plant's treated effluent likely discharges into the surrounding waters of the Florida Keys, which are part of the larger South Florida coastal ecosystem. This region includes sensitive coral reefs, seagrass beds, and mangrove habitats that support diverse marine life. The plant plays a critical role in protecting water quality in the Florida Keys National Marine Sanctuary and adjacent waters.

The plant is located in the Florida Keys, a chain of islands bordering the Atlantic Ocean and Florida Bay. Treated wastewater from the facility likely discharges into nearshore waters that are part of the larger South Florida coastal ecosystem. This area supports sensitive coral reefs, seagrass meadows, and mangrove forests, which are vital for fish nurseries and marine biodiversity. Protecting water quality is essential to prevent nutrient pollution that can lead to algal blooms and coral degradation.
