We offer excellent service and expert advice to meet all your wastewater needs.

Adoption of an existing sewer

We adopt existing sewers that pass Section 102 of the Water Industry Act 1991. This requires the sewers to be properly designed, constructed and maintained. Once we adopt these as public sewers, we will maintain them at our expense. However, all costs prior to adoption are at your own expense.

Adoption of a new sewer

You can make an agreement with us to adopt a sewer prior to construction. You will need to apply for a Section 104 Sewer Adoption.

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.

Our sewer adoption charges depend on your specific site requirements, the leaflets at the bottom of this page explain how we calculate the right charges.
