You can construct mains and services on new developments sites yourself if you're registered with the Water Industry Registration Scheme (WIRS), a national scheme overseen by Lloyds of London.
Or you can appoint a WIRS registered Self Lay Providers (SLP) to do the work on your behalf. They will need to contact us, with your authorisation, to agree our costs. We'll work closely with developers who are considering laying water mains as part of a multi-utility programme.
The Water Industry Code of Practice provides guidance that covers the provision of water infrastructure for housing and industry development in England and Wales.
Our self lay addendum to this document details our specific requirements for self-laying water mains and services.
Although you can lay new water mains, the final connection from the newly laid main to the existing infrastructure needs to be completed by us. Once we've connected and adopted the new main, you've got the option to connect the service pipes to the new properties as another self lay option.
To apply for self lay at your development, we'll need:
- a site plan
- A soil analysis report (for developments not deemed Greenfield)
- A completed application form
