Boil Water Notices
What to do when a boil water notice is issued in your area?
We understand that a boil water notice is inconvenient however, protecting our residents from health risks is our priority.
When a boil water notice is issued, affected people should continue to boil their water (for at least one minute) until advised the water is safe again.
The boil water notice process:
- When contamination occurs in our reticulated network, we first issue a boil water notice to the affected residents via different channels:
- E-text or email sent to all affected ratepayers (who have registered their contact details with us)
- E-text or email sent to the affected non-ratepayers residents who have subscribed to our water alerts
- Media release which goes to all media outlets plus CDHB, elected members, etc.
- News story posted on our website
- Facebook post
- A detailed investigation of network is carried out to identify the source of contamination and manage the issue.
- Daily water sampling continues until we confirm three clear sample results, when free of chlorine disinfection.
- Once a Boil Water Notice can be lifted, we follow the same steps as outlined in number 1- above to inform the community
Important: residents with a restricted water supply are advised to disinfect their water storage tank(s). Refer to our guidelines [PDF, 129 KB]
