Properties built after 1920 may have two drainage pipes: one for foul water (from the loo, washing machine, washbasins etc) and one for surface water (rainwater which falls on your roof).
Water from your surface water drain goes straight to local rivers and streams, while the contents of your foul water drainage pipe goes to one of our sewer treatment works.
If these two drains are connected incorrectly, it can mean that the foul water from your loo and appliances goes straight into rivers and streams, contributing to pollution.
We estimate that thousands of homes across our region are inadvertantly connected in this way. If you suspect that your drains are connected incorrectly, you can find out what to do here. You can also speak to us on 0345 672 3723.
