Pipework responsibility - sewage

The sewerage system serving your home includes pipes, drains and sewers – find out who is responsible for which parts.

You are responsible for the drains that serve your home up to the boundary of your property or to the point where it joins with pipework from another property, whichever is closest.

You are also responsible for:

  • pipes connected to private treatment systems such as septic tanks, soakaways and private treatment works
  • other systems which do not connect to the public sewer such as surface water pipes which discharge directly to a watercourse
  • internal drainage pipes or above ground pipework such as guttering or vent stacks.
