Self Lay 

As an alternative to having new mains and service connections installed by us, developers can arrange for the work to be carried out by qualified contractors.

A National Code of Practice is now available. This Code of Practice is for when a Developer appoints an independent Self-Lay Provider (known as a SLP) to undertake the contestable work of designing and/or installing water mains and services on a new development site. It details the delivery processes, requirements for the work and specifies the role of SLPs and Water Companies. Additionally you can find guidance from Ofwat on Self Lay here.

The work must be carried out by a company that is accredited with the Water Industry Registration Scheme (WIRS) which is administered by Lloyds Register.

As an alternative to having new mains and service connections installed by a Self Lay Organisation, developers can arrange for the work to be carried out by us.

Contestable List

Below is an extract from the Self lay Code of Practice Version 3.1 – dated May 2017 to cover the non-contestable activity.

The Water Company should allow the SLP to do all elements of work to provide water supplies to New Developments other than those defined as non-contestable in Table 1.

Table 1: Non-contestable activities in the design and construction of water mains and services

DESIGN
Design work for network reinforcement
Sizing pipes - Water Companies retain responsibility for this part of the design work (See Sections 3.5.3 and 3.6.3)
DESIGN APPROVAL
Approving on-site water distribution designs (except where self-certification arrangements are in place)
INSTALLATION
Network reinforcement works (i.e. to secure an adequate supply to the site) whose construction heightens the risk of damage to existing water distribution systems or interrupting supplies to existing customers.  (See note below)
Mains connections that involve heightened risk to existing assets or could affect supplies to existing customers.  (See note below)
Source of water connection to Water Companies' existing assets
Service connections larger than 63mm diameter.
Service connections less than 63mm on existing mains where the Water Company assess that the condition of the main or the material heightens the risk to existing assets or could affect supplies to existing customers. (See note below)
COMMISSIONING
Decommissioning redundant mains following a diversion.


Note - Restrictions on SLPs undertaking work apply when the Water Company assesses that the construction works significantly heightens either the risk of damage being caused to their assets.

Should you wish to discuss these requirements, please contact the team.

Codes for Adoption

What are 'Codes for Adoption' ?

 

The Water Act 2014 introduced changes to the Water Industry Act 1991 (WIA91) requiring Ofwat to issue statutory codes for adoption agreements. These are the agreements that developers or self-lay providers (SLPs) enter into when they want an appointed water or sewerage company to take over responsibility for infrastructure they have constructed. They are the agreements entered under section 51A WIA91 for water infrastructure.

 

The codes were introduced by Ofwat to ensure a consistent approach in the sector, that developers, new appointees and SLPs, are provided with confidence that they will receive the services they want from water companies to enable their own business in providing contestable services.

 

The water code documentation was approved by Ofwat in September 2020. The approved set of documents can be found below and also on the Water wxbaoxv.com website.

 

Codes for adoption will go-live from 1 January 2021.

 

In preparation, all water companies are required to publish certain documents.

 

We are pleased to share our documentation below, which we will continue to add over the coming weeks.

 

Design and Construction Specification (DCS)

The South West Water Draft Design and Construction Specification can be found here.

 

Local Practices

The DCS allows South West Water to introduce a local practice in certain permitted areas where our operational requirements are not adequately covered in the document. Our draft local practices are contained within the Design and Construction specification and highlighted blue. If you have any thoughts/comments on them, which you want to discuss, please email them to developerservicesselflay@southwestwater.co.wxbaoxv.com .  We will then publish our finalised version by the 1st January 2021.

 

Annual Contestability Summary (ACS)

The connection work that is open to competition is known as “contestable” work. This category includes the majority of work a Developer needs to serve a new development and includes all work to lay and test new mains and services. Water Companies have a responsibility to maintain wholesome water supplies to Customers, some higher risk work may be defined as “non-contestable” and can normally only be carried out by the Water Company itself.

 

We will publish our ACS each year and evolve the document to enable further contestability each year.

 

You can view our Annual contestability table here.
