Greasy waste
Our greasy waste management system is referred to as FOGMan (Fats, Oils and Grease Management). The initiative has been developed to ensure customers pump out their grease arrestors at the frequency prescribed on their Industrial Waste Permit.
Better management of greasy waste in the sewer system leads to less blockages and overflows of wastewater to the environment.
How a grease arrestor works
Fats, oil and grease rise to the top and solids sink to the bottom, reducing the amount of these substances that flow into the sewer. Grease and solids build up over time requiring the grease arrestor to be pumped out regularly. All business involved in the cooking and preparation of foods will normally require a grease arrestor. For more information please refer to the brochure below.

Your responsibilities
- Have an appropriately sized grease arrestor
- Have your grease arrestor pumped out at the frequency prescribed on your Industrial Waste Permit
- Use a licensed liquid waste contractor (LWC)
- Report pump outs to the Water Corporation within seven days
- Maintain good house keeping practices
Pump out frequency of a grease arrestor
A pump out frequency will depend on the type and size of a grease arrestor, the nature and volume of wastewater produced by your business. Pump out frequencies are determined and applied when the Water Corporation assesses your industrial waste application to discharge to sewer. A frequency can be re-assessed by request but it’s important to note;
- The re-assessment process will involve a number of inspections of the wastewater in your grease arrestor to determine the point of grease arrestor failure. For more information please refer to the brochure below.
- Re-assessments may also result in an increase to the pump out frequency.
- A grease arrestor frequency reassessment charge will apply.

Using a FOGMan liquid waste contractor
The grease arrestor must be pumped out by a liquid waste contractor (LWC) that is licensed by the Department of Environment and Conservation (DEC). FOGMan LWCs are those who have signed on to a code of practice to service a grease arrestor to a required standard and report pump outs on your behalf.
Ultimately it is the responsibility of the permit holder to ensure the grease arrestor is pumped out and reported to the Water Corporation.
