Sewer and Sewage Laws
A pipeline which normally conveys foul sewage and/or surface water run-off from more than one property.
Public Sewer Responsibility
A sewer that has been adopted as a public sewer or was in use prior to the 1st October 1937. (Note: This general definition does not apply to properties in inner London, for which local guidance should be sought).
Who is Responsible for a Private Sewer?
If a problem occurs at a point along a private sewer, the properties which drain to that point are jointly and equally responsible for the cost of dealing with the problem. The cost of clearing a blockage would therefore be paid for equally by all property owners upstream of the blockage.
