Frequently Asked Questions

How do I Maintain my Grease Trap?

Maintaining and cleaning any size/design grease trap is explained in our manual.


  • Removing all of the accumulated FOG (fats, oils & Grease) on the surface

  • Sucking out all of the greywaters from the Trap [or leaving rich bio-logical liquid]

  • Discarding the food waste on the bottom of the unit.

  • Then, the unit could be washed down, ensuring all components and chambers are thoroughly cleaned and free of any waste that could cause a blockage in the Trap or pipes.

  • A detailed cleaning record should be available for a Water Authority / Environmental Health Inspection.

How are Grease Traps Cleaned?

ALULINE a licensed waste disposal contractor will use a tried & tested method to remove the FOG (fats, oils & Grease), greywater, and food waste in one action.

Approved and professional cleaning is carried out using mechanical pumping equipment depending on the size of the grease trap. If the grease trap is situated indoors, this operation may need to be done after hours in restaurant operation. 


How Often Should the Trap be Cleaned?

Wastewater regulations and IS  UK EN 1825 parts 1 & 2 state that all grease traps should be emptied when "25% of its volume is filled with organic waste). 

As a guideline, the above regulations need all untreated grease traps to be de-sludged, emptied and cleaned at least x4 times per year. This requires regular monitoring of the Trap. Location and design are essential at a design stage. Internal traps must be inspected regularly. Staff training will be a major factor in weekly/monthly emptying.
