What is the difference between a grease trap and a grease interceptor?
Grease traps and grease interceptors are both plumbing devices for grease removal from industrial wastewater discharge streams. The grease trap is generally thought of as the smaller indoor device, usually with the holding capacity of no more than 250 gallons, and is typically installed below a sink. Grease traps are usually made of steel and often designed with just a single compartment. The grease interceptor is generally considered the large pre-cast concrete tank, typically with a liquid holding capacity of up to 5,000+ gallons and designed with two separate compartments. The sizing criteria is in accordance with the current Uniform Plumbing Code.
