What to Flush down your loo!

Added on 16 April 2018

What is allowed to be flushed down the sink, toilet or private foul drains?

Natural human waste (pee and poo), toilet paper, and wastewater from baths/showers, sinks, washing machines, and dishwashers.

The following items must not be disposed of down the drain, sink or toilet:

All facial, baby, cleaning and wet wipes (even those labelled flushable can cause blockages), sanitary products, nappies and cotton buds must be placed in the bin. These items are the main causes of blockages.

Fats, kitchen oil, and grease (known as FOG) and food waste also cause major blockages. Wipe out your pans and other greasy items with a kitchen towel before washing them. Put the kitchen towel in the bin and pour any used cooking oil into a container to dispose of or recycle it.

Do not jet-wash/brush items such as mud, grass, animal waste and other garden debris into an open manhole. These should be disposed of via garden waste bins/refuse bags.

Disposing of these items via the drain, sink or toilet is called sewer abuse and is seen as a criminal offence, under S111(1)(a) of the Water Industry Act 1991.

We need your help to try and prevent further blockages – not only will it reduce the risk or sewer flooding to you and your neighbours, but will help keep the cost of your bill down. 


Thank you for your support.
