Green Cove Springs South WWTF - Wastewater Treatment in Clay County, Florida

Green Cove Springs South WWTF is a municipal wastewater treatment facility located on Leonard C. Taylor Parkway in Green Cove Springs, Clay County, Florida. The plant serves a population of approximately 4,000 residents, supporting the local community's wastewater management needs. As a facility in the United States, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements. For a plant serving around 4,000 people, typical treatment includes secondary treatment as a minimum standard, with potential additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the local watershed, which ultimately drains to the St. Johns River, a major waterway in northeastern Florida. The St. Johns River flows northward to the Atlantic Ocean near Jacksonville, supporting diverse aquatic ecosystems and providing recreational and economic value to the region.

The plant's discharge enters the St. Johns River basin, a slow-moving blackwater river that flows through extensive wetlands and floodplains. The river supports a variety of fish, birds, and plant species, including manatees and sturgeon in its lower reaches. Downstream, the river empties into the Atlantic Ocean at Mayport, where freshwater and saltwater mix, creating productive estuarine habitats.
