Drains and sewers

The pipe that exits your property is called a drain.

When your drain joins one from another property it becomes known as a sewer from that point onwards.

Difference between a drain and a sewer?

  • a drain is a pipe that drains water and waste from a building and other buildings which belong with it, for example a garage
  • a lateral drain is a length of pipe which carries wastewater away from your property to a sewer. It is usually located outside your property boundary, often under a public pavement or road. A lateral drain might run under your property if you share a sewer with your neighbour
  • a sewer collects water and waste from the drains of a number of buildings

Who is responsible?

  • homeowners and landlords are responsible for drains up to the connection with drainage from another property, even if that connection is under a road or neighbouring property
  • owners of former council houses are usually responsible for looking after drains up to where they connect with drainage from other properties. From that point on it can be the responsibility of the owners, Thames Water or Ealing Council, depending on the location of the sewer and layout of the estate

Problems with drainage

The council has statutory powers to ensure that privately owned drains are kept clear and in good working order.

To report problems with drainage, contact property regulations.

Building regulations compliance

Repairs and new drainage works must comply with the building regulations.

Contact building control services if you need advice or to arrange an inspection.
