We would like to apologise to any customers who attempted to contact us on Saturday 13 August.
A fault in our telephone system meant calls to our 24-hour emergencies and faults number, 13WATER (13 92 83), were not answered from 3 pm on Saturday afternoon until early Sunday morning.
We believe planned maintenance works caused an electrical outage which triggered the fault.
As the 13WATER phone number is a critical service to our customers, we will be undertaking an independent review into the incident.
The review will help us to improve our service in the future.
