Common questions
How often must a grease trap be pumped out?
Your water authority's trade waste agreement sets the frequency, commonly every 4 to 13 weeks for food businesses depending on trap size and load.
Why am I billed for 1,000 litres when my trap is 500?
Most contractors run a 1,000 litre minimum charge because the truck, travel and disposal costs are the same regardless of trap size.
