Sewage and drainage

What are drains and sewers?

Drains are single pipelines which convey foul sewage and/or surface water run-off from a single property. A drain is still a drain even if it goes past the boundary of your property and remains so until it joins a sewer.

Sewers are pipelines which normally convey foul sewage and/or surface water run-off from more than one property. Sewers may be either private or public sewers.
