Cost prompts cautious approach
Plans for a forecast $6million upgrade of the water treatment plants in Gore and Mataura should be finalised by the end of the year.
The Gore District Council has submitted plans for peer review as it is taking a cautious approach because of the predicted cost.
It has been estimated the Hilbre Ave plant will cost $1.1million for the reservoir upgrade, and $1.5million for the treatment plant upgrade.
The Mataura plant is forecast to cost $1.4million and the East Gore plant $1.8million.
3 Waters assets manager Matt Baylis said the peer review would look at the best options and different technologies available for the upgrade.
Ultraviolet treatment was among options being investigated, Mr Baylis said.
The upgrade had been budgeted for and would be paid for through loan funding, he said.
The council owns and manages water supply assets valued at $12.5million and it also oversees the Otama water scheme.
Council chief executive Steve Parry said the GDC’s proposal to upgrade the water treatment plants to make them fully compliant with New Zealand drinking water standards, as outlined in its annual report, was subject to a “critical review”.
“This review was due to the council staff wanting to make sure the strategy for the upgrade reflected the latest treatment technologies available, together with ensuring the most optimised usage of the three treatment plants in the Gore and Mataura urban water networks,” Mr Parry said.
“This has necessitated a peer review of current thinking.”
