Grease interceptors are an essential part of kitchen drainage system to prevent grease, liquefied fat or oil from entering the main sewage or septic tank treatment system. FOG's allowed to escape into the wastewater disposal system can disturb the efficiency of treatment facility and ultimately harm the environment. For all kitchens involved in catering, small processing establishment or serving at least 30 meals in a day grease trap installation is important. Grease trap are equally useful in regular domestic kitchens.

Posted by Nigel on Monday, 28 April 2014


I have plans to create a restaurant near Durham and have been advised to install a greasetrap to cater for approx 120 meals per day - would this GT1-150 be suitable. My building controller advises it has to be tested to EN1825, can you confirm this please. Looking further ahead I have the option to extend into a neighbouring property which could allow me to do functions for 300 - 400 people. Can you recommend a grease trap for this number also . Thank you Nigel

How do I keep my grease trap working efficiently?


  • Posted by Aj Edgar on Tuesday, 31 December 2013

    Installing a grease trap is not enough to save your kitchen from wastewater backups in the sink or foul odour. It is important to clean out or pump out the grease traps periodically. A failed grease trap would allow FOGs to escape into the city sewer drains leading to high penalties. Do not treat your regular grease traps as food disposal units. Scrape off all unfinished food particles into the food recycling bins including gravies, sauces, or milkshakes. Use a bacteria (available as blocks or liquids) additive or enzyme cleaners to keep the grease interceptors free of all deposits.
