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 visit your site and get back to you with an estimate 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).

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

  • an estimate for the cost of the work required
  • a plan showing the proposed main laying scheme
  • a legal agreement for you to sign and return.

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:

  • an estimate for the cost of the work required
  • a plan showing the proposed connection position.

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.
