Section 102/104 Sewer Adoptions

Sewer Adoption / Taking in Charge

When it comes to drains, understanding Section 102 and Section 104 Agreements is essential, especially for clients looking for drainage assets in the UK. These agreements help ensure compliance with regional water and sewage companies for any businesses interested in sewer adoption.

Section 102

Section 102 covers existing sewers and allows an individual or business to apply for a private sewer already in use. There are many things to consider when you’re looking to take on a private sewer including:
  • The method of construction or requirement of any repairs
  • Whether the sewer or works are adapted or will be required, for a general system of sewerage provided or proposed for the whole or any part of that location;
  • The location of the sewer e.g. not under a highway or an existing project
  • The number of buildings in proximity using the sewers

Section 104

Section 104 focuses on new private sewers to be used by the local sewerage company and maintained at their own expense. The sewer must be designed in compliance with the regulations and maintained for a period after finishing before full completion of the project. This results in a private drainage system for areas such as highways, roofs, driveways and more.

There are many steps in gaining either a Section 102 or Section 104 agreement and complex systems can require expertise to understand. Starting your plans early is the best way to get approved as soon as possible and we’re here to help at each step of your application and process.
