If you would like to put forward newly constructed or existing sewers and associated assets for adoption, the Sewer Adoptions team will be happy to guide you through the process. We will ensure that the assets proposed are designed and constructed to meet the required standards to allow them to be adopted into Yorkshire Water as public assets. We will take ownership of the network and assets from the developer who constructed and installed it.
Yorkshire Water is the Statutory Sewerage Undertaker for the Yorkshire Region. However, if you wish you can approach a New Appointment and Variation (NAV) to adopt your sewer network. For further details, please refer to the Ofwat website.
Water companies in England have implemented the Sewerage Sector Guidance as a requirement of OFWAT’s Code for Adoption (2020). All sites put forward for adoption must now be designed and constructed in accordance with the Design and Construction Guidance, Local Practices and Technical Standards contained within the Code for Adoption (2020).
The biggest change is the inclusion of guidance as to which sustainable drainage systems (“SuDS”) are capable of adoption as sewers. Here at Yorkshire Water we are very much aligned to the implementation of sustainable drainage systems and we want for the assets that we take ownership of through the adoption process to contribute to our overarching strategies, policies and performance commitments by:
- managing surface water sustainably on the surface
- creating resilience to climate change
- increasing bio-diversity net gain
- contributing to net zero carbon
Our Sustainable Drainage System (SuDS) Design Guidance sets out the key principles for design of SuDS assets to be vested in Yorkshire Water.
Drainage systems considered at the earliest stages of site selection and design are easier to integrate into developments influencing other aspects of the site such as design, layout and function, and thereby reducing impermeable areas wherever possible. Successful designs need to consider local policy documents developed by the Local Planning Authority and should take into account the Local Flood Risk Management Strategy.
We encourage early and effective engagement during your planning and pre planning stages of the development, so please come and talk to us so we can work together to help deliver sustainable developments for the future.
Our developers guide to the adoption and vesting of new sewers (S104) provides all of the information that you need when offering new sewers and sewerage assets for adoption and an overview of the vesting process and requirements once your development site has reached 51% occupancy. It also reinforces Yorkshire Water’s approach and requirements to adopting surface water components which is very much aligned to CIRIA C753 ‘The SuDS Manual’.
