Hello Blog Readers,

Happy New Year!

Thames Water last year visited over 200 restaurants and food establishments in a bid to reduce the number of sewer blockages in the area.  Several restaurants did not have a grease trap installed and 43% did not know what a grease trap is used for.


In the run up to the festive period many water companies appealed to customers to bin waste and not block the sewers.  In Dublin city a FOG programme has been in operation since 2008 to reduce the amount of FOG waste entering the sewers.  The FOG programme requires FOG producing kitchens to install and maintain a grease trap.  Regular inspections are done and failure to comply will result in a fine.


Blockages are frequently discovered when back-ups (when waste water cannot drain it will come back up from the sink or toilet) and sinks fail to drain or drain very slowly.  The sewage system is designed to handle sewage waste and water not Fats, Oils, Grease (FOG), wet-wipes, cotton buds and nappies.  Other items such as false teeth, toys and clothes have been found in the sewers!! Each year water companies spend millions dealing with fatbergs and 75% of these are caused by FOG waste.

Thames Water clears on average 80,000 blockages each year with most of these blockages caused by FOG waste.  Restaurants and commercial kitchens should install a grease trap to stop FOG waste entering the water system.  Grease Guardian offers both manual and automatic grease traps which are suitable for all sizes of kitchens.

More information regarding the Grease Guardian grease trap range is available on the website.  A FAQ section regarding grease traps can also be found on the website.  Please contact us on the below number or email address if you have any questions.
