I have been told that part of the property's drainage is connected to the wrong sewer. What does this mean?

Many houses have two separate sewers:

• The foul sewer takes waste water from toilets, bathrooms and kitchens to the sewage works for treatment
• The surface water sewer takes rainwater from the roof and conveys it to a local watercourse (eg river or stream).

If you find that your property has wastewater pipes discharging to a sewer intended for rainwater only, it will cause pollution. This is known as a misconnection and you will need to undertake remedial work to put it right.

The  ConnectRight website provides guidance on what to do to find any misconnections and how to put them right - just use the "check your existing connections" guide.
