JEA Mandarin WWTF - Jacksonville, Florida Wastewater Treatment Plant

JEA Mandarin WWTF is a water reclamation facility located in the Mandarin area of Jacksonville, Florida. Serving a population of around 50,400, it is part of the JEA utility system, which provides water and wastewater services to the greater Jacksonville region. The plant is situated inland, more than 50 kilometers from the Atlantic coast. As a U.S. facility, JEA Mandarin WWTF operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. The plant has a designed capacity of 1.00 million gallons per day, and its treatment processes are expected to meet secondary or advanced standards typical for facilities of this scale. The plant's classification as a water reclamation facility suggests it may employ advanced treatment for reuse. The treated effluent from JEA Mandarin WWTF is discharged into local waterways that ultimately drain into the St. Johns River, a major river in northeast Florida. The St. Johns River flows northward to the Atlantic Ocean, supporting diverse aquatic ecosystems and serving as a critical water resource for the region. The plant's operations are subject to state and federal regulations to protect water quality in the river and its tributaries.

JEA Mandarin WWTF discharges into the St. Johns River watershed, which flows north through Jacksonville and into the Atlantic Ocean. The river supports a variety of fish, birds, and plant species, including manatees and sturgeon. The plant's inland location reduces direct marine impact, but its effluent must meet strict nutrient limits to prevent algal blooms in the river and downstream estuary.
