Unplanned changes to the water and sewerage network, such as flooding, may lead to drinking water quality incidents. This can lead to a situation when the water supply is no longer fit for human consumption.
If an incident happens, a customer may not be able to use the water supply. This needs to be communicated to customers. Customers may also have to provide information to the wholesaler in order for them to monitor the incident.
Obligations under the codes
Drinking water quality incidents are managed by the wholesaler under specific incident control plans and procedures. These may be agreed between the wholesaler and other relevant authorities.
Wholesalers are responsible for managing water quality incidents as described under Process E4 of the Operational Terms. In this instance, retailers may reasonably be called upon by wholesalers to provide assistance.
