A new community playing field will also be developed in the area, the Queenstown Lakes District Council said.
In a press release issued this morning, council property and infrastructure manager Peter Hansby said the project would provide for current and future stormwater capacity as growth
in the area continues.
"The rapid pace of growth in Frankton has driven the development of a long-term strategy for the future management of stormwater in the area.
"We've identified the best possible long-term solution and plan to kick off stage one of the upgrade at the end of January 2019.''
The recently completed Eastern Access Road project addressed a significant portion of the land area to the north of Grant Rd, with a main trunk stormwater system capturing and transporting stormwater to the Shotover River Delta, Mr Hansby said.
"The North East Frankton line will manage the remaining stormwater in the Frankton Flats area, allowing for the future demands of the whole catchment area and rain events greater than
one in every 20 years.''
A playing field is also planned for above Remarkables Primary School.
"These works are significant and will see deep trenches dug along the pipeline route, along with thrusting the pipe under State Highway 6.''
The excess fill will be transported to the site above the primary school and turned into a sports field.
"Access to sports fields is another area under pressure so it's fantastic to be able to make this added benefit happen for our growing community,'' Mr Hansby said.
The new field is expected to be open for use from this spring.
Work is set to start at the Frankton lakefront late January and is expected to last until August.
It will cause "minor disruption'' to the Frankton Track.
Diversions will be in place and the details shared online. Residents are asked to follow all signage in place.
