A drain carries waste water and surface water through a pipe.
A lateral drain sits outside the boundary of the property it serves. Lateral drains usually run through a neighbour’s garden or is situated on the highway beyond the property boundary.
A sewer pipe carries waste water and surface water from more than one property.
Who has responsibility?
Problems with or a blocked drain is usually the responsibility of the property owner. You may be covered under your household insurance or a specific drainage insurance scheme. Alternatively, you could attempt to clear the blockage or repair the defect yourself or consult a drainage contractor to carry out the required work.

If you think that you have a problem with a public sewer, a former private sewer or a lateral drain you should report it to United Utilities by telephone 0845 746 2200 or online. If you are not sure who is responsible please go to the United Utilities website which has some useful information and may help you.
