Sewers for adoption

small houses and sewer

We can consider applications to adopt new or existing sewers.  If we agree to adopt your sewer, an adoption agreement must be entered into.  Once we have adopted your sewer, it will become part of our sewerage network and will be maintained by us.

Would you like us to adopt an EXISTING sewer?

  • If you would like us to adopt an existing sewer, you must submit plans and details of the sewers for initial consideration before we will consider the adoption of the sewer.

Would you like us to adopt a NEW sewer?

  • The adoption of new sewers remains optional. Should you decide to apply for adoption, the new sewers can be designed and constructed in accordance with Sewers for Adoption
  • If you would like us to adopt a new public sewer we will firstly assess your application and a Section 104 Agreement must be made with us prior to construction of the sewer
