A national code of practice for the self-laying of water mains is now available. This sets out the requirements from the initial application and proposal through to entering into a formal agreement and completion of the work on site, with subsequent adoption by the water company.
The first step with any prospective self-lay project is confirmation that the SLP / contractor has the appropriate level of competence to carry out the work.
The Water Industry Registration Scheme (WIRS) has been put in place by the water industry to effectively assess and monitor the performance of all SLPs and contractors, hence accreditation under this scheme is now the accepted method of assessment.
Close liaison and clear and timely communication between all parties is fundamental to successful progression and completion of the self-lay process.
This scheme is operated by Lloyds Register EMEA. To see a full list of accredited SLPs and contractors, or apply for accreditation yourself, please visit the Lloyds Register website
The relevant sections of the CDM Regulations (2015) apply to all design works carried out by or on behalf of the Water Company – both the Water Company’s representative (Approving Design Engineer) and the SLP’s representative (SLP Designer) are Designers under CDM Regulations when the design of Self-Lay Works is being generated and accepted for adoption.
Codes for adoption
As you may be aware Ofwat are looking to introduce a standard practice across the water industry in England for water companies to follow when adopting self-laid mains.
We are planning to publish our document by September, and it will need to be read in conjunction with the Water Sector Guidance which can be found on Water UK’s website.
Design and Construction Specification
Our Design and Construction Specification is coming soon, it will assist practitioners with the planning, design, construction and commissioning of a Self-Laid Main and Service Pipes to supply domestic and industrial/commercial properties.
We will be including a number of local practices for meter pairing and commissioning, timing of the generation of plot numbers, water company design service offerings and design Self-Certification Scheme.

As a SLP customer of ours, you deserve the highest standard from us. Most of the time we achieve this but sometimes we get it wrong.
