Iron Bridge Regional WRF - Seminole County, Florida Wastewater Treatment Plant

Iron Bridge Regional WRF is a major wastewater treatment facility located in Seminole County, Florida, serving a population of approximately 242,403. The plant is situated in the central part of the state, an area characterized by a humid subtropical climate and numerous lakes and rivers. As a large agglomeration, the facility plays a critical role in managing municipal wastewater for the region. Under the U. S. Clean Water Act, the plant operates with an EPA NPDES permit that sets effluent limits to protect water quality. For a facility of this scale, advanced treatment is typically required to meet stringent nutrient reduction standards, especially in Florida's sensitive watersheds. The designed capacity is 1.00 million gallons per day, indicating the plant's ability to handle peak flows. The treated effluent is discharged into the St. Johns River basin, which flows northward to the Atlantic Ocean. The receiving waters support diverse aquatic life and are important for recreation and drinking water supplies. The plant's operations help maintain the ecological health of the St. Johns River and its downstream estuary.

The plant discharges into the St. Johns River basin, a major river system in Florida that flows approximately 310 miles north to the Atlantic Ocean near Jacksonville. The river supports a rich ecosystem including manatees, alligators, and numerous fish species. Downstream, the river forms a large estuary that is critical for commercial and recreational fisheries. The region's flat terrain and high water table make nutrient management essential to prevent algal blooms and maintain water quality.
