Thames Water Bit It Don't Block It

Yuck Don't feed the fatberg
5 years 200,000 blockages
5 years 18,000 homes flooded

This is what happens when you put the wrong things down the drain.

Never pour oil and fat down the sink. When it cools it sets hard clogging your pipes.

The majority of blockages are caused by cooking fat and oil, which congeal in the sewers, forming a thick layer around the pipe.


Running the hot tap and pouring washing up liquid down the sink won’t prevent fats or oils from blocking your pipes.

Each year approximately 1,000 homes and 5,000 gardens in the Thames region flood with sewage as a result of blockages in the sewers.

Only flush pee, poo and toilet paper down the loo.

Millions of people suffer the misery of blocked drains every year - a result of unsuitable products being flushed down the loo or washed down the drain.


Wet wipes do not break down in the loo as they are made of plastic. Even if they say ‘flushable’ they should never go down the toilet.

Even wipes that say ‘flushable’ or ‘biodegradable’ cause blockages. Although they disappear when you flush the loo, they take a number of years to disintegrate.


Avoid a fatberg like this by putting these items in the bin:


How to avoid a fatberg

Tips to keep your drains blockage free

There are 6.7 million blocked drains each year in the UK.

A plumber could cost over £200 to clear your pipes.

Use containers

Margarine tubs, plastic pots and jam jars make handy containers to capture cooled, leftover cooking fat and oil - which you can put in the bin.

Clear your plates

Scrape your plates of food and fat before washing up or loading your dishwasher.

Use a bin

Keep a bin in the bathroom for everything that isn’t pee, poo or toilet paper.
