Food and Oil Interceptor

Commercial trade waste contains food, fat, oil and grease which can solidify in sewers. If not managed appropriately, this can cause sewer blockages which may lead to sewer spills within your property or downstream in the sewer network. 

Commercial (and sometimes industrial) customers will normally need a food and oil interceptor (FOI) installed to pre-treat this waste before it enters the sewer system. A food and oil interceptor is a tank or pit that intercepts food, fat, oil and grease before the waste enters the sewer. Sometimes they're called a grease trap.

Regular pump-outs of food and oil interceptors are required as the fat, oil and settled food particles and solids accumulate over time. It is your responsibility to ensure that the food and oil interceptor is pumped out at the intervals stated in your commercial trade waste consent. Typically, we require them to be pumped out every four months.

Remember, if you fail to pump out your grease trap at the required frequency, you will be subject to our non-compliance process.
