Oil & Grit Interceptors are the technical solution for the separation of oil and grit from stormwater runoff at fuel stations, car parks, commercial spaces, contracting environments and industrial wash down bays. The interceptor uses gravitational force and varying densities of oil and water to remove oil from drainage.
Oil and grit interceptors are an effective and simple solution to separate and store grits and all types of oils from lightly contaminated stormwater and wash-down water. They are required for the separation of heavy solids (sand & grit) and floating hydrocarbons from storm water or wash down areas. They are typically used in industrial and commercial applications where there is potential risk for contamination from hydrocarbon products into waterways.
The multi chambered treatment tank is installed close to the collection point (to ensure the oil reaches the interceptor before it emulsifies or pollutes the area) allowing for the stormwater / wash down water to flow into the settlement chambers prior to entering a storm water lateral or disposal system.
