Grease Trap Emptying

Kitchen grease traps should be emptied and cleaned regularly to ensure they function correctly, remain hygienic and do not start to allow fat, oil or grease into the sewer.

The frequency of emptying will depend on the type of grease trap installed, the tank capacity and the extent of usage. 

Grease traps need to be emptied long before they are full – generally when the fat content reaches around 25%.  Always follow the manufacturer’s guidelines and monitor the trap regularly.

Signs that your grease trap is not functioning correctly include water draining slowly from sinks and drains attached to your trap, water backing up and not draining away, unpleasant odours coming from sinks and drains.
