Self-Lay

If a development requires a new water main or sewer, the developer may ask the water or sewerage company to install the pipework. Alternatively, they may choose Talbot Pipelines Ltd to do the work, which is known as self-lay.

Self-lay providers must be accredited under the Water Industry Registration Scheme (WIRS) which is recognised by all the water companies and Water UK. Under WIRS, Lloyd’s Register carries out technical assessments of the service providers who elect to be accredited for contestable works associated with installing water infrastructure.

Using a self-lay provider such as Talbot Pipelines Ltd can be preferable as we will utilise our years of experience to co-ordinate and streamline your installation. This will enable you to focus resource and time on delivering the development.

The process for using self-lay is laid out in the stages below. Where the responsibility refers to Developer or SLP, Talbot Pipelines Ltd can take on the responsibility on your behalf.

The Process:

 

1. Advanced enquiry stage

The developer or the SLP contacts the water company to confirm the feasibility of supplying the proposed development and provides the information necessary for the water company to do a technical evaluation.

The water company confirms its ability to supply and specifies the point of connection and validity period of the information.

2. Application stage

The developer or SLP makes a full application by submitting all the required information, together with a completed application form to the water company.

3. Design stage

The developer or SLP either submits the design of the water network to the water company for vetting, or the developer or SLP requests that the water company designs the water network.

The water company sends details of the estimated asset payment, non-contestable charges, security and legal agreement to the developer or SLO.

4. Self-lay notification

Following the pre-start meeting, return of signed legal agreement and payment of relevant charges the developer or SLP submits the notification to start to lay mains to the water company.

5. Main-laying installation

The SLP constructs new water mains, notifying the water company of any changes and of the intended testing and disinfection dates. The water company audits and inspects construction and may witness testing of the new main.

6. Main-laying completion

The SLP completes main-laying to the required specification and rectifies any defects identified during the inspection and audit. The SLP provides the water company with the ‘as laid’ drawings and test certificates. The water company arranges the main connection, issues the vesting certificate and makes the asset payment to the developer or SLP. The maintenance period starts from date of commissioning.

7. Service connection notification

The Developer or SLP submits notification to lay services in accordance with the water company’s self-lay arrangements. The notification is only issued after the developer or SLP confirms that the private pipework has been checked or self-certified as meeting the Water Supply (Water Fittings) Regulations.

8. Service connection installation

The SLP makes the service connections in accordance with the previously issued notification, and either fits water meters or requests that the water company fits meters. The SLP then provides fill details of each connection, including the postal address, and meter details (if fitted) to the water company.

9. Protection of installed apparatus

The developer or SLP makes sure that all installed apparatus is protected against damage until the development is completed and roads or footpaths are fully constructed.
