Billing queries

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:
