Section 102 of the Water Management Act allows the owner of an existing private canal to request the adoption of their sewers. Our guide to offering private sewers available for acceptance provides all the information needed to provide existing sewers for acceptance. To apply for an existing sewer system, please complete the application form (PDF 122 KB will be opened in a new window). In the case of significant developments (generally, ten or more houses), the normal method used to achieve this transfer is through Section 104 of the Water Industry Act (1991), commonly referred to as the Section 104 Agreement (short for S104). From 1 April 2020, Ofwat introduces a new standard practice throughout water management in England, covering the introduction of new sewers. The new procedure is described in Water UK`s new Channel Sector Guidelines (SSGs), which will replace the Sewers for Adoption guidelines. If you want to introduce a new sewer system, you need to fill an S104 application (PDF 223 KB will be opened in a new window). You will find help for your application in our S104 process guide (PDF 115 KB will be opened in a new window) and our technical guide (PDF 96 KB will be opened in a new window). If you have your technical agreement from us for your sewer system design, you must be in a section 104 agreement so that we can formally handle the sewers. Before starting construction of the new sewers, you should apply for a pre-inspection that rehabilitates their technical reception. Once we have received this and all fees are paid, one of our inspectors will hold a pre-departure site meeting for the new development.
If you want to offer newly built or existing sewers and pumping stations to be accepted by us as public sewers, our engineering team will help guide you through the process and ensure that the facilities meet the required standards. The adoption of a drainage system by a section 104 agreement concerns a drainage system that drains private areas (such as roofs and driveways) as well as the drainage of highways (if both flow into the same pipeline system). The last authority to adopt is the Sewerage Undertaker. The cost of entering into such an agreement depends on the size of the development and drainage system required. We inform you three months before your maintenance period expires, and then you should check the sewers and make sure there are no maintenance problems. If your research were to point out that sewers are subject to an adoption agreement, you should be aware that they are not currently owned by the water distribution company and that if things go wrong, it is not the water company that is responsible for the repair. It is also possible that the developer may not be able/unable to repair the sewers or, if they stop the business, the owners may be responsible for the sewers. We would always recommend checking who the developer is, if there are any likely complications, and the likely timing of acceptance.
