New water mains

If you’re building a new road to adoptable standards as part of a large domestic or commercial development, you’ll probably need a new water main – that’s where we come in.

We’ll handle your application for a new main and take care of the main laying and main connection work for you. 

Once you've applied and made the applicable payment, we’ll do a survey and get back to you with a quote for the work within 28 days. Our service partner handles the main laying and main connection work, which normally takes no more than 90 days (but do bear in mind, if the work is on a busy road, it may take longer as we’ll need to notify the local council).

What do you need?

Building a new road to adoptable standards? You can request a new main from us by applying below.

If you’re not building a new road, you probably won’t need a new water main but you may need a new water connection to our existing mains network.

You will need:

  • basic site information

  • site location plan

  • site layout plan

  • F10 notice

  • additional information (if applicable - check form for details).

Need building water as well as a new water main? You can request a supply of building water when you apply for a new main (see the application form above).

If, for whatever reason, you don’t request a building water supply in your main application but later decide that you need one, you can make a separate application using the form below.

Once you’ve applied and made the payment, we’ll get back to you within 28 days with:

  • a quote for the cost of the work required

If you’re building on land that wasn’t previously greenfield or used purely for housing, we’ll need you to send us a completed contaminated land risk assessment form as part of your connection application. This is so we can check there are no chemicals in the soil that might affect our pipes and fittings.

Please bear in mind, you’ll need to arrange the risk assessment privately.

Getting a new water main and connections

Click on the tabs below to find out what you need to do – and what we’ll do – at each stage of your journey.

Before you apply

What to think about before you apply:

  • Do you want to hire a self-lay provider (SLP) to lay the new main and make the connections?
  • What was the previous use of the land you’re developing on? (Greenfield or brownfield?)
  • If the land is brownfield, have you had a contamination assessment done?
  • Do you know what size connections you need? (Household connections are usually 25mm).
  • Are you eligible for a reduction to your infrastructure charges? (Click here for more details).
  • Will you be installing any water re-use systems? (E.g. rainwater, boreholes/springs or grey water?)
  • Is your development project notifiable to the HSE? (If so, we’ll need a copy of your F10 Notice).

Step 7: Lay your service pipes

What you need to do:

Dig and lay the service pipes for each property on site, according to the agreed design plan and the specifications enclosed with your connection quotes.

What we’ll do:

If there are any off-site connections needed (connections to an existing main outside the boundary of your site), we'll dig and lay the pipework for these ourselves.

We may also arrange a visit to your site to make sure that the pipework you've laid meets regulatory standards before the connections are made.

Step 8: Book in your connections

What you need to do:

  • Complete and return the checklist to us at least 14 days (for on-site connections) or 28 days (for off-site connections) before you need your new water supply.
  • If the properties are new, send us a copy of the council letter confirming the address of each new property.
  • Keep in mind that the plots must be ready, and the pipework correctly laid, before we come to site, otherwise we’ll need to cancel the work and charge you an additional fee for the aborted visit.

What we’ll do:

We’ll pass your work order to our service partner, Network Plus, who will:

  • Plan in the work and set a connection date that’s within 14 days (for on-site connections) or 28 days (for off-site connections) of receiving your checklist.
