Oxidation ditches: wastewater treatment plants in Florida
21 plants · 5% of the state · 59 MGD reported by 17 plants
Klarifi identifies 21 publicly owned wastewater treatment plants with oxidation ditches in Florida, 5% of the 449 plants in the state (59 MGD reported by 17 plants). The largest is Daytona Beach Westside Regional WRF in Daytona Beach at 12.71 MGD.
Oxidation ditches are ring-shaped activated sludge reactors with long retention times, common at plants between 0.5 and 10 MGD. They are recognisable from the air by their looped channels and rely on surface aerators or brush rotors, which are frequent replacement and energy-efficiency projects.

Sources and methodology
Flow, permit and violation figures come from the EPA's ICIS-NPDES discharge monitoring records. Population served comes from the Clean Watersheds Needs Survey 2022. Treatment structures are identified by Klarifi's review of aerial imagery, and capital improvement projects are extracted from published municipal budget documents. Violations are counted over the last three years of monitoring reports.
