A storm drain adjacent to oil-filled equipment requires oil containment to prevent oil from being released into a city sewer.
The drain prior to installation of a custom-made Petro-Barrier Box.
The Petro-Barrier Box slides into a flanged insert that allows the Petro-Barrier Box to be attached with screws. The Petro-Barrier Box has a manual overflow valve for emergency water backup; the valve can be opened with a T-handle to relieve backed-up water.
The grate is replaced. Under the grate are several layers of pre-filter materials to keep the Petro-Barrier Box free of dirt and debris.
