New water connections - large diameter
If you’re building a new home or commercial property (such as a shop, office or industrial building), unless you’re planning on harvesting rainwater, you will probably need a new connection to our water main.
What will the service provide?
This service is for large diameter new water connections.
For commercial buildings, if you need a large amount of water, especially water used in industrial processing, you may need a large water connection.
If a dedicated water supply is needed for firefighting purposes, you may need a connection of over 63mm.
If you have any queries on the process, our detailed guidance notes at the bottom of this page should be able to help.
How long will it take?
There are several stages to the new water connection process:
How can I apply?
To apply for a larger connection, please fill in this application form and return it to developer.services@dwrcymru.com
How much will it cost?
The cost of a new large diameter water connection is made up of four different charges:
1. An initial application fee
This is an upfront non-refundable fee, paid on application, using a valid credit or debit card. Once you come to pay the connection charge, we’ll then deduct the application fee, so you’ll just have to pay the difference:
- A larger connection of over 63mm (where a dedicated water supply is needed for firefighting purposes) is an upfront non-refundable fee of £2,500+VAT to be paid on application. This will be deducted from the cost of delivering the scheme, so you’ll just have to pay the difference.
2. A connection charge
- For larger connections, we will build up a bespoke quote. VAT is only applicable where the properties are not exempt from VAT.
3. A water infrastructure charge (not applicable if it's for a fire main)
This is a one-off charge:
- £512 per property for standard connections
- £512 x relevant multiplier for larger connections (you can find details of our multipliers on pages 22-23 of our schedule of charges)
4. A waste infrastructure charge (not applicable if it's for a fire main)
This is a one-off charge, set by our regulator Ofwat, which is applicable for properties who are also connecting to our sewerage system and opt for a standard new water connection:
- £512 per property for standard connections
- £512 x relevant multiplier for larger connections (you can find details of our multipliers on pages 22-23 of our schedule of charges)
