Clara Gravity Separator

The Clara Gravity Separator offers a patented oil-grit-trash-water separator for stormwater that can be used as a standalone treatment or in a treatment train configuration. Clara Separators remove dirt, oil and floatables by gravity separation. The built-in internal high-flow bypass traps pollutants in this below-ground structure even during peak runoff events. Clara Separators are recommended when suspended solids concentrations are greater than 200 mg/L and oil is greater than 10 mg/L

Three technicians and a manager install a Clara Gravity Separator from Newterra at a new construction site for industrial use
