Water Supply
If you want to be connected to the public water supply network you must apply to us in writing.
Approval for connection
We will advise you of our decision to permit you to connect to a watermain within 14 working days from the date of your application.
Where we approve your application, we will advise you of any related costs or charges you will have to pay and any conditions which you will need to comply with. In some situations we can only issue a ‘conditional approval’. This will explain the conditions you are required to comply with to obtain final approval for connection.
It is illegal for anyone other than Northern Ireland Water or an authorised contractor to make a connection to a watermain. In both instances work must not start until the appropriate charge has been paid and any conditions complied with.
Once you have completed all necessary work to the correct standard, we will connect you to the water supply system - normally within 21 days.
What if there is no existing watermain?
You can request a new main, either on your own or with your neighbours. The new main must serve two or more properties. We will provide a new main where the financial and operational conditions are met.
We will give you a decision on whether or not we will provide a new water main within two months from the date of your application.
There are two ways in which we can provide a new main. These are explained in detail in our ‘Developer’s Pack ’. Please call Waterline: 0845 744 0088 to request a copy free of charge.
We must provide a water main within three months of agreement to do so. If we do not, you are entitled to interest payment on the amount you have pre-paid to us, for every day of delay.
