Our sewerage network
When sewage disappears down a plug hole or the toilet it flows through the waste pipe and into a drain. From there it usually flows into a public sewer.
Householders are responsible for the maintenance and repair of their drains until they connect with the public sewer.
Usually the public sewer runs underneath the nearest road, but sometimes it can be some distance away.
In our region the public sewer system stretches for thousands of miles.
Wherever possible the sewage flows through sewers by gravity until it reaches the sewage treatment works. Sometimes, particularly in flat areas, the sewage needs to be pumped to the works from a pumping station.
Our sewers are regularly inspected and maintained to ensure they operate as effectively as possible.
