Sewer adoptions

If you wish to offer any newly-constructed or existing sewers and pumping stations for adoption, our team of engineers will assist in guiding you through the process, and will ensure that the assets meet the required standards to allow them to be adopted as public sewers.

We have also created a handy site sewer construction guide (PDF 3,675 KB opens in a new window) for contractors and operatives who are constructing sewers, which offers advice on how to avoid some common site errors.

Adopting new sewers

Under Section 104 of the Water Industry Act 1991, a developer can apply to transfer ownership of their newly-constructed sewers to United Utilities by way of an ‘Adoption’ agreement.

Our Guide to S104 new sewer adoptions (PDF 120 KB opens in a new window) provides all of the information that you need to offer new sewers for adoption. To apply for a new sewer adoption, please complete the sewer adoption application form (PDF 278 KB opens in a new window).

All applications will be technically assessed to make sure that they meet specific industry standards. For our requirements for technical drawings, please see our standard construction details document (PDF 2,181 KB opens in a new window).

Changes to the standards for the construction of new foul sewers and lateral drains have been proposed. However, until the new ‘Mandatory Build Standards’ are agreed and implemented, we will continue to work with Sewers for Adoption – 6th Edition, which is published by the Water Research Centre whose website you can get to here.

Further legislation, Section 42 of the Floods and Water Management Act, confirms that, in future, a Section 104 adoption agreement must be in place before any new sewer can be connected to the existing public sewer network. As yet, a date for this change has not been agreed.

Adopting existing sewers

Under Section 102 of the Water Industry Act 1991, the owner of an existing private sewer can apply to transfer ownership of their sewer to United Utilities.

Our S102 sewer adoptions guide (PDF 97 KB opens in a new window) provides all of the information that you need to offer existing sewers for adoption. To apply for an existing sewer adoption, please complete the application form (PDF 114 KB opens in a new window).

Adopting pumping stations

Our team of Developer Engineers will assess all submissions for the adoption of pumping stations against Sewers for Adoption – 7th Edition & the latest version of the United Utilities Pumping Stations Addendum document (PDF 1,956 KB opens in a new window).

The pumping station is usually covered under the same Section 104 agreement as the gravity sewers on the development.
