STUART STP Wastewater Treatment Plant, Stuart, Florida

STUART STP is a municipal wastewater treatment plant serving the city of Stuart in Martin County, Florida. The facility serves a population of approximately 22,250 people, placing it in the medium agglomeration category. The plant is situated near the Atlantic coast, within 50 km of the ocean. As a U.S. facility, STUART STP 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 a plant of this scale, secondary treatment is typically required, with possible additional nutrient removal standards due to Florida's sensitive coastal waters. The plant's treated effluent is discharged into the St. Lucie River watershed, which flows into the St. Lucie Estuary and ultimately the Atlantic Ocean. The estuary supports diverse aquatic life, including seagrass beds and marine fisheries, and is an important migratory corridor for birds and fish. Protecting water quality in this region is critical for both ecological health and local tourism.
