About the project
In response to the cryptosporidium outbreak that affected Queenstown’s water supply back in October 2023, we installed a temporary UV treatment solution at Fernhill Reservoir above the Two Mile water intake to provide safe drinking water in the area.
We've now installed a permanent UV treatment plant located next to the Two Mile intake and Sunshine Bay Trail to ensure drinking water in Queenstown, Fernhill, and Sunshine Bay remains safe and compliant.
We’ve also added additional building space for a pre-UV filtration plant room next to the UV treatment plant. The addition of pre-UV filtration will protect other treatment equipment and help to remove lake algae (Lindavia Intermedia) from the water supply, making the system more robust and easing the nuisance algae can cause in our network.
The pre-UV filtration project is already included in the 2024-2034 Long Term Plan. By constructing the additional building space now, we create the opportunity to fast track the installation of this infrastructure within the next three years.
With installation of the new UV treatment solution complete, the temporary solution used by Fernhill Reservoir will be redeployed elsewhere in the district.
Work was carried out by Fulton Hogan, with assistance from Veolia and Filtec.
