About Boil Water Notices

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:Logo: Selwyn Gets Ready

  1. When  contamination occurs in our reticulated network, we first issue a Boil Water Notice to affected residents via different channels:
      • Letter drops to residents
      • E-text or email sent to all affected rates payers who have registered these details with us
      • Community reach via Selwyn Gets Ready network - you can subscribe to these alerts.
      • Media release which goes to all media outlets plus CDHB, elected members, etc.
      • News story posted on Council website
      • Facebook post
  2. The reservoir and reticulation are then chlorinated to disinfect the supply from any possible contamination.
  3. A detailed investigation of network is carried out to identify the source of contamination and manage the issue.
  4. Daily water sampling continues until we confirm three clear sample results, when free of chlorine disinfection.
  5. Once a Boil Water Notice can be lifted, we follow the same steps as outlines in number 1- above to inform the community.
  6. Residents with a restricted water supply are advised to disinfect their water storage tank(s). Refer to our guidelines
