Parking Structures

Clarifiers (oil/water separators) should be installed in covered parking structures and garages to pretreat pollutants such as oil & grease from vehicles, loosened asphalt, sand, cement, particles and other pollutants resulted from steam cleaning of the garage or washing of the cars. The clarifier is designed for gravity separation of free oils along with some floatable and settable solids from water.
