More Wanaka streets will be disrupted over the next six to eight months as the council begins drinking and wastewater projects to cater for town growth and boost network resilience.

Last week, Wanaka learned a section of Ardmore St would be closed in both lanes for six months from Monday, to allow contractors to upgrade the lakefront and build 110 car parks.

That project should be finished by the end of September.

The drinking water projects should be completed by November while the major wastewater project should be done by the end of the year.

Queenstown Lakes District Council (QLDC) property and infrastructure general manager Peter Hansby said there would be some disruption during the wastewater upgrade, including partial and possibly full road closures and traffic diversions.

However, access would be maintained for residents, rubbish and recycling services, and emergency vehicles.

The first stage of the major wastewater upgrade starts on part of Aubrey Rd this month.

It involves the upgrade and replacement of wastewater pipes and lateral connection pipes from houses between the corner of Rata St and Aubrey Rd down to Bremner Bay.

Closer to Mt Iron, a new water supply pipe will be connected to existing pipes under the Sir Tim Wallis Dr roundabout and the Albert Town wastewater pump station will get new network connections.

A new pump station is being planned but this part of the project is still being finalised.

Meanwhile, contractors have started clearing a site for a new drinking water pump station on the corner of Bills Way and Mt Aspiring Rd.

Work has also started on a new 2km water pipeline along Golf Course Rd, up Macpherson St and towards Anderson Rd.

“Following site clearance, we’ll start building.

“There may be periods where it seems nothing is happening on site, and that’s when we’ll be installing the below-ground pipe work,

Wanaka Community Board chairman Barry Bruce said in his March 31 report the Bills Way pump station would provide increased resilience and supply of drinking water to west Wanaka.

“These works also enable future projects related to the wider Wanaka supply,” he said.

Mr Bruce said the council aimed to reopen Golf Course Rd to two lanes “in the coming weeks”.

However, Lake Hawea must wait a bit longer for a major wastewater system upgrade.

Mr Bruce said the project was still being designed and staff were refining options for the pipeline and pump station.

There were no material updates to information released in December and public information sessions should be delayed until the concept designs were finished in June or July, Mr Bruce said.

The pipeline alignment required consultation with specific landowners, which ideally needed to happen before wider community engagement, he said.

The existing Hawea Wastewater Treatment Plant was built in 1988 and upgraded in 2000.

It is unable to meet current and projected demand.

Short-term upgrades, with a design life of five years, would provide some relief until the long-term solution could be put in place, Mr Bruce said.
