In a busy kitchen - fats, oils and grease (FOG) in liquid form can easily enter the sink, but this simply moves the problem on rather than solving it. Even liquid oils can quickly solidify once in the sewer system, causing blockages to the kitchen drainage and downstream sewers. 

It is important that disposing of FOG, particularly when produced in large quantities in commercial kitchens, is done responsibly and sustainably. Blockages, flooding, and pollution of the environment can all be consequences of build-up in the sewer network. 

How fats, oil and grease can enter the sewers from your kitchen:


  • Kitchen sinks from washing up
  • Internal and external drains
  • Dishwashing machines
  • Workstations
  • Floor mopping
  • Cleaning equipment 
  • Failing to operate fat traps/grease removal units correctly​

How grease traps can help​
Food service establishments have a legal and moral responsibility to make sure local communities and the environment are protected. And grease traps help to stop FOG from leaving your commercial kitchen, entering the sewer network, and causing nasty blockages.In short, they work by collecting your wastewater – which allows the FOG time to separate from the water – so it can be disposed of later. Meanwhile, the wastewater should be discharged into the sewers.​

Finding the right size​
If your grease-trapping equipment isn’t the right size for your commercial kitchen, then it won’t do its job properly. That means FOG can still escape from your kitchen and end up in the sewers, causing a nasty blockage. ​
