Ranfurly Boil Water Advisory Lifted

The Boil Water Advisory for Ranfurly has been lifted today, Tuesday 2 September 2025. Residents no longer need to boil water for drinking or food preparation.

A temporary ultraviolet (UV) treatment plant, borrowed from Selwyn District Council, has been installed and commissioned to meet required drinking water standards.

This plant provides the necessary protozoa barrier (required under the current legislative framework) and will remain in place until the water treatment plant upgrades are completed.

Ranfurly residents are advised to:

• Flush plumbing system - run all cold water taps for at least 5 minutes to clear water from your pipes
• Flush appliances – clean and flush coffee machines, ice makers and water dispensers etc.
• Flush header tanks to ensure turnover of fresh water
• Replace or clean water filters.

While this is a positive milestone, Conserve Water Notices and Boil Water Advisories may still be issued if source water conditions exceed the capability of the temporary UV treatment system.

Please note: the Boil Water Advisory for Patearoa remains in effect. Upgrade work on the Patearoa Treatment Plant is being prioritised and is progressing well. We will continue to keep the community updated.

Council acknowledges the inconvenience this advisory caused and sincerely thank the residents for their patience, cooperation and resilience throughout this period.

We appreciate everyone’s continued support as we work to deliver safe, reliable drinking water for all our communities.
