1. What is Sewer Adoption?
- Legislation covering the adoption of sewers, including pumping stations and other ancillaries, is contained within the Water Industry Act 1991. Section 104 covers the adoption of private sewers to be constructed at a future date subject to an agreement with the sewerage undertaker (IWNL).
- Sewerage assets, offered for adoption, should be designed and constructed in accordance with the standards that are included in the latest edition of Sewers for Adoption. This is published by the Water Research Centre (WRc) and representatives of both the Home Builders Federation and Water UK were involved in its preparation.
- Once adopted, the sewers are vested in the ownership of IWNL.
