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 delivery team 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).

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?
  • 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).
