When to report issues elsewhere 

Repairs to water infrastructure will often fall under your regional wholesaler. Smaller repairs may require an outside contractor.

You should let us know if there is an outage, as that may impact your billing, but when there are issues such as a burst water main, or localised water discoloration, you should get in touch with your wholesaler immediately.
