Adoption diversions and closures

Adoption of a new sewer (S104)

You can make an agreement with us to adopt a sewer prior to its construction. You will need to apply for a Section 104 Sewer Adoption Agreement. On adoption the sewer will become part of our sewerage network and maintained at our expense. We follow the nationally approved document 'Sewers for Adoption 6th Edition', published by WRC on behalf of Water UK.

Diverting an existing sewer (S185)

Abandonment of a public sewer (S116)

In some circumstances it may be possible to close a public sewer so that it can be abandoned, which may remove a potential restriction from any future development of the site and may make any site remediation works easier. Before we consider applying to close part of the public sewer network, we need to be absolutely certain that the length being considered is no longer in use and has become redundant.
