Pine Island WWTP - Advanced Wastewater Treatment in Saint James City, Florida

Pine Island WWTP is an advanced wastewater treatment facility located in Saint James City, Florida, on Pine Island in Lee County. The plant serves a population of approximately 1,275 residents, providing essential sanitation services for this coastal community. Its location within 10 km of the Gulf of Mexico places it in a sensitive coastal environment where treatment quality is critical. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 934.99 thousand gallons per day and an average discharge volume of 567.81 thousand gallons per day, the facility operates below its capacity, indicating room for future growth. As a US facility, it 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, which set strict effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Caloosahatchee River estuary and ultimately the Gulf of Mexico. This region supports diverse aquatic life, including seagrass beds and mangrove forests, which are sensitive to nutrient pollution. The plant's advanced treatment helps minimize environmental impact on these ecologically important coastal habitats.

Pine Island WWTP discharges into the Pine Island Sound watershed, which connects to the Caloosahatchee River estuary and the Gulf of Mexico. This coastal area supports seagrass beds, mangroves, and diverse marine life, including manatees and sea turtles. Advanced treatment reduces nutrient loading, helping to prevent algal blooms and protect the sensitive estuarine ecosystem.
