We want to make paying your bill as hassle-free as possible so we have taken steps to make interactions more convenient by developing a web-based Self Service Portal.

This allows you to log into your NI Water account online and access your details at a time that is convenient to you.

Once registered, you will be able to:

• view the account balance;
• view the payment plan of individual schedules;
• view bill and payment history;
• pay a bill; &
• manage account details.

You can also:

• view septic tank desludging request history; &
• process a new septic tank desludging request.

The registration process is simple – details are in the instruction sheet below:
