Grease trap installation cleaning and maintenance is essential to remove Fats, Oils & Greases (FOG) and is required by Irish law.
What is a Grease trap?
A grease trap is an external collection tank usually required for restaurants and takeaways which collects “FOG” (Fats, Oils & Grease ).
What are Fats, Oils & Greases (FOG) ?
FOG is a liquid waste generated in commercial kitchens during food preparation and washing up. It originates from butter, lard, vegetable fats, oils, meats, nuts, cereals, etc. It is washed down the drain into the public sewer where it cools, solidifies and accumulates and eventually causes a blockage. FOG also causes problems at waste treatment plants so it is important these liquids are collected in grease traps.
Installing & Maintaining a Grease Trap
Most FSE Operators will be required by the TEL to install and maintain a grease trap to limit the amount of FOG discharged by the FSE to the public sewer. More than one grease trap may be required for larger FSEs. The grease trap will separate the FOG from the wastewater. The FOG then rises to the top of the trap for eventual collection and disposal.
Grease Traps should be located downstream of the following:
• Pot sinks;
• Rinse sinks;
• Soup kettles or similar devices;
• Steam combination ovens;
• Water cooled wok ranges;
• Any other sinks, fixtures or drains through which a significant amount of oil, fat or
grease may be introduced.
Please note that grease traps that use chemicals or enzymes additives to dissolve the collected FOG are not acceptable to Cork County Council. Bacteria additives only may be used where the FSE Operator has demonstrated to Cork County Council or its agents that the use of such additives enables compliance with the conditions of the TEL.
Emptying Grease Traps
Grease traps must be cleaned on a regular basis to ensure the continued removal of FOG and also to prevent odours. Generally, grease traps should be cleaned when FOG and food solids occupy 25% of the grease trap. FOG should be removed from the top of the chamber and food solids should be removed from the bottom of the trap. Frequency of cleaning will depend on the grease trap, throughput, kitchen practices, and the type and size of FSE.
It is recommended that the services of a specialist contractor should be engaged to clean the grease trap and to remove and treat the waste material. This contractor shall have a waste collection permit and shall transfer the solid waste from the bottom of the grease trap to a permitted composting facility. The FOG fraction of the waste material may be recyclable. Cork County Council recommends that the FSE Operator enters into a written contract with the contractor for the cleaning of the grease trap and for the removal and treatment of the waste material for an agreed period of time.
