The public consultation on the proposal to chlorinate several council-owned water supplies opens today. 

Most of our water supplies are chlorinated. We’re proposing to permanently chlorinate the rest: Upper Takaka, Hamama, Motueka, Riwaka/Kaiteriteri and Richmond, as the best way to ensure we’re supplying clean, healthy drinking water. 

Check out the full consultation document online here or collect a hard copy from your closest council office or library. Your feedback is invited until 4 September. 

The proposal to chlorinate has been prompted by the findings of a government inquiry into the 2016 gastroenteritis outbreak in Havelock North after the town’s drinking water supply became contaminated with Campylobacter. 5,500 people became ill and 45 people were hospitalised. The outbreak is thought to have contributed to four deaths.  

One of the key recommendations from the Havelock North inquiry that is relevant to our water supplies is having a multi-barrier approach to prevent contamination.  

This is crucial because our water sources can be affected by a range of contaminants. A multi-barrier approach uses several methods to treat water, reducing the risk of contaminated water reaching the point of supply and people. Examples of barriers are:   

  • Source protection 
  •  Filtration 
  •  Ultraviolet treatment 
  •  Chlorination (residual disinfection)
