Please complete this form if you would like to make a legal agreement with us to adopt an existing sewer under Section 102 of the Water Industry Act 1991. A £1,000 non-refundable deposit is required to cover the initial application costs. All additional costs incurred thereafter will be recharged to the applicant.
Before applying for a sewer adoption, please review our guidance notes.
Important to note: the design and construction of your sewer
Section 102 of the Water Industry Act 1991 covers the adoption of existing private sewers. For sewers to be adopted under this Act they must be properly designed, constructed and maintained.
All costs prior to adoption are at your own expense. However once adopted the sewers become public sewers and will be maintained by Thames Water at our expense.
