Oil/Solids InterceptorsCast Iron
Cast iron oil/solids interceptors use gravity separation to pull petroleum-based oils, sand, and sediment out of industrial waste streams. Built for garages, auto service bays, car washes, gas stations, and fleet maintenance floors, they let solids settle and oil rise so cleaner water passes to the drainage system.

Oil/Solids Interceptor FAQs
Common questions about Josam Oil/Solids Interceptors
Oil/solids interceptors are designed to capture oils, petroleum products, sediment, sand, and other solids before they enter the drainage system.
Josam oil/solids interceptors are available in various capacities to match flow rates and specific application requirements.
Oil interceptors are typically required in parking garages, auto service facilities, manufacturing plants, and other locations where oil or petroleum products may enter floor drains.
Oil interceptors use gravity separation—oil floats to the top while solids settle to the bottom, allowing clean water to flow through to the drainage system.
An oil/solids interceptor handles industrial waste streams containing petroleum-based oils, sand, and sediment from garages, car washes, gas stations, and fleet maintenance areas. A grease interceptor, by contrast, captures fats, oils, and grease (FOG) from commercial kitchens. The two serve different contaminants and applications.

Common applications
- Auto repair & dealerships — gravity separation in service bays.
- Car washes and gas stations — oil and sediment capture.
- Parking structures — protect storm systems from vehicle fluids.
Need Oil/Solids Separation?
Josam oil/solids interceptors provide effective oil and sediment separation for industrial applications. For commercial-kitchen FOG control instead, see our cast iron grease interceptors.
