What happens to the fat from London’s sewers
Dear Mr Hollier
Thank you for your recent email.
I have discussed your enquiry with our Pollution Control Team. They have
confirmed we do not
routinely record the tonnage of fat removed from the sewers across our
region. However, we do try to

Our usual method for keeping the sewers clear is high pressure jetting.

We believe a large proportion of the fat and grease incorrectly disposed of
in our sewers comes from
food service establishments. These will include fast food restaurants.
We are aware that fat and grease disposal practices vary widely between
different companies. To
address this we do encourage restaurants to install fat traps. I am
pleased to confirm a number of
restaurants in the Thames Valley do have fat traps installed.
As a further step to prevent the incorrect disposal of fat and grease into
our sewers, we make visits to
restaurants. The purpose of these visits is to provide advice and guidance
on the correct way to
dispose of fat and oil.
I hope my reply has gone some way to answer your enquiry. If you have any
further questions please
contact us on 0845 9200800.
