San Carlos Park WWTP - Advanced Wastewater Treatment in San Carlos Park, Florida

San Carlos Park WWTP is an advanced wastewater treatment facility located in San Carlos Park, Lee County, Florida. The plant serves a population of approximately 1,500 residents and operates as part of the region's municipal wastewater infrastructure. Its coastal location within 10 km of the Gulf of Mexico places it in a sensitive environmental zone. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 825.22 thousand cubic meters per year and an annual discharge volume of 681.37 thousand cubic meters, the facility operates below its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Florida Department of Environmental Protection, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that ultimately drain into the Gulf of Mexico. The surrounding watershed supports diverse aquatic ecosystems, including estuaries and mangrove forests that are critical for fish and bird species. The plant's advanced treatment helps protect downstream water quality in this ecologically sensitive coastal region.

The plant discharges into the Caloosahatchee River basin, which flows into the Caloosahatchee Estuary and then into the Gulf of Mexico. This watershed supports seagrass beds, oyster reefs, and mangrove habitats that are vital for marine biodiversity. Advanced treatment at this facility reduces nutrient loading, helping to prevent harmful algal blooms and maintain the ecological health of the estuary.
