Wanaka's
multimillion-dollar wastewater processing treatment plant
Project Pure has been officially handed over to the
Queenstown Lakes District Council.
The council entered into a contract with UGL Ltd in July 2007
to design, construct and operate the treatment plant, next to
Wanaka Airport.
The handover comes after a two-year operational period was
extended because of problems early on with the plant's
operation.
"There have been adjustments made along the way to address
issues such as odour management," QLDC acting infrastructure
general manager Ken Gousmett said.
"I am happy to report the recent operational history has
largely been satisfactory particularly around the quality of
treated effluent, which is of a high standard."
The handover was attended by QLDC deputy mayor and Wanaka
Community Board chairman Lyal Cocks.
"It is great to see the plant operating as it should. It is a
significant piece of infrastructure making a major
contribution to the clean green reputation of this district,"
Mr Cocks said.
Project Pure brought an end to the practice of discharging
treated waste water into the Clutha River. Instead, the
treated water is discharged to airport land in an extensive
underground soakage network. A 10-year warranty has been
provided by UGL Ltd, which commenced from the official
handover date of November 30, 2011.
The ongoing maintenance and operation of the plant is now in
the hands of the council's water contractor Veolia Water Ltd
(previously known as UWI Ltd).
