Self Lay

As a Developer, you have the option to employ an accredited Self-Lay Provider (SLP) to complete all mainlaying and service connections on your new development site.

In order to undertake this work, your SLP must be accredited with Lloyds Register under the Water Industry Registration Scheme (WIRS). Full details can be found at http://www.lr.org/

The following sections detail the various self-lay mains services we offer from Point of Connection Enquiry to a full main laying applicaiton, plus individual service connections into our existing network.

The Supporting Documentation and Guidance section contains our Policies and procedures.

  1. This application form should be used at a detailed planning stage if you are intending to use a self-lay provider (SLP) to design and install your new water main and service connections.

    Our written response will be a feasibility study of supplying water to your development, detailing the following information;

    A network plan indicating the proposed Point of Connection into our existing main(s);

    Details of any re-enforcement required to our network.

    Dependent on the size of your site, we will provide a response to a full application in 21 days.

  2. We are committed to offering developers as much choice as possible when it comes to the installation of new mains and services. The choices we currently provide are:• The developer can choose to employ a self-lay operator (SLP) to carry our the work• The developer can ask us to do the work on their behalf• The developer may want to see the cost options available before making a decisionIf you would like to see all the cost options prior to making a decision, you will need to fill out a mains requisition application. We will then provide you with all the costs for the different options and a design plan for the site. If you chose the self-lay option, you will need make an application for self-laying mains.
    All the information you will need regarding a self-lay operator carrying out the work or to requisition a main from Yorkshire Water can be found below.


    Mainlaying

    Please follow this link to find a list of accredited SLP’s.

    If you have decided to use a Self-Lay Provider (SLP) to lay your water mains and services and they are designing the on site mains, they will require a point of connection (Poc) into our network before making an application to Self-Lay mains.

    If you require access to our plans this can be done by filling out a web mapping request form, and emailing the application to
    webmapping@yorkshirewater.co.uk.

    Our mains design guidelines will assist you in complying with our requirements and contain our approved materials lists which will ensure you procure the correct fixtures and fitting for the site.

    When you are ready to start work on site, please let us give us 10 days notice, by completing the attached weekly whereabouts form. This will allow us to start any non contestable works (work that can only be done by Yorkshire Water).

    Once the mains are laid, they will require chlorinating, to ensure this meets our required standards please read both Water UK principles of water supply hygiene and our chlorination guidance document.

    Once the main is laid and you have a chlorination pass certificate from our water quality scientist, you need to make an application to connect the new main to the spur main we have laid as part of the non contestable works, or if you are connecting between phases please fill in our routine in line connections form.

    The main is now ready for vesting and any asset payment we have agreed to pay. Prior to this you must have produced an as-laid drawing of the new main, to ensure this meets our required standards, please read our Main Laying as built drawing guide.

    You will also need to meet our inspector on site to agree any remedial action or receive a mains vesting request form. This will allow you to apply for the asset payment.

    Service Connections

    Please give us 10 days notice when you are making service connections to the new main by completing our weekly whereabouts form and send it to SLP_@yorkshirewater.co.uk.

    This will give us time to ensure the property complies with the water regulations. If you are making plot connection to any properties that will require connection into our existing mains, this will need to be risk assessed by our technical operations team, please fill in our self-lay connection to existing off site mains request form and send it to SLP_@yorkshirewater.co.uk.

    We try to give developers as much choice as possible when it comes to the location of water meters whilst retaining ongoing operational control of our network. Our meter location policy will assist you with the options available. In some cases meters into blocks of flats will need to be installed internally.

    Our water meter guidance document can help with this but information can also be found in the mains design document. Some property types will also require sprinkler systems fitting to comply with building regulations. Our document on installing a domestic sprinkler system will assist you with the design of these systems.

    When plot connections have been made, we need to know about this, so we can set customers up on our billing file. Please fill in our site meter installation form and send it to SLP_@yorkshirewater.co.uk.

  3. This application form should be used when you are ready for the branch connection installation further to countersigning of the Section 51 Agreement plus payment of the associated infrastructure contribution (if applicable).

    We aim to make the connection within 21 calendar days from receipt of your complete Request for work form.

    However, where branch installations cannot be completed within 21 days due to Highways restrictions or legislative conditions beyond our control, we will provide an alternative date for the connection within 9 calendar days of receiving a your request for work form.



  4. If you wish to employ a Self-Lay Provider (SLP) to make a connection into our existing water network, please complete and return the attached form to: SLP_mailin@yorkshirewater.co.uk

    Your application must include the following information:

    Upon receipt of this application, we will raise a consultation with our technical support engineer who will determine whether the SLP has approval for the connection. Details of the contestable/non-contestable works can be found in the supporting documents here.

    Once we have received feedback from our consultation, we will then be in a position to either approve or reject the proposals. Please note, the SLP must not lay any pipework until the approval / rejection form has been issued by Yorkshire Water.

  5. If you decide that you want Yorkshire Water (YW) to install the new water mains and services on your site, you may want a water availability assessment so you can understand what it will take to feed the site.

    By completing the development enquiry request form we will be able to indicate the issues faced in servicing the site. When making and application for YW to install mains to your site, you will also need to consider the previous use of the site.

    Our contaminated land assessment form will help you with this.If you require any previous water supplies to be disconnected please complete the permanent disconnections form or in some cases mains may have to be diverted to allow you to carry out construction.

    Please complete the public water main diversion request form to allow us to provide costs for this work and a revised route for the main.
