A Government inquiry was sparked by the 2016 Havelock North gastro outbreak, which was linked to four deaths, and called for a major overhaul of water supplies, including mandatory treatment.

We're upgrading almost all our water treatment plants, essentially building new ones with state of the art filtration and treatment systems, in our drinking water standards project - Tautiaki Wai Māori. 

The Tairua, Pauanui, Whitianga, Coromandel Town and Whangamatā (Beverley Hills) plants have been completed.

The programme for the remaining seven water treatment plant upgrades will be completed by 2023/24 and has been included in the 2021 – 2031 Long Term Plan. An additional water treatment plant will be built in the Puriri area and is expected to be completed in 2024/25.

Next steps:

  • Wentworth Valley (Whangamatā) –Construction on the Wentworth Valley, Whangamatā, water treatment plant started on Wednesday 5 May and should be completed by March 2022.
  • Moana Point (Whangamatā) –Enabling works have been completed and the building consent application has been submitted.
  • Onemana - The design is being prepared and construction is expected to begin in 2022. 
  • Hahei –Drilling has finished to establish potential locations of new underground aquifers. We will update you more on the new water treatment plant and the exact location when this has been finalised. 

The plants are fitted with the latest technology and methodologies for treating our water including Evoca-supplied membrane units, new filtration, dosing and monitoring equipment.

All of these upgrades will ensure our drinking water quality complies with the current NZ Drinking Water standards.

The drinking water treatment plant at Thames was upgraded more recently than the other plants, and is not due for an upgrade as part of this project.
