Kingston Infrastructure Works

Given its proximity to fast-growing Queenstown, Kingston has long been considered an appropriate location for more housing stock. However, this has been limited by the lack of supporting Three Waters infrastructure (water supply, wastewater, and stormwater).

Zoning for the area immediately south of the existing Kingston township was revised under Plan Change 25: Kingston Village Special Zone, allowing for a residential development of approximately 750 new homes. Since then, QLDC has worked with Kingston Village Ltd (KVL) to agree on the infrastructure requirements for their new development.

Furthermore, most existing properties in Kingston manage their own onsite three waters systems. These systems are of varying quality and present their own challenges now and into the future. Because of this, the Three Waters infrastructure we’re delivering has been designed to eventually provide capacity for and allow connection of existing dwellings within Kingston. However, properties within the township will need to continue managing their own water and wastewater systems until we complete further planning, design, and financial analysis work and engage with the Kingston community as part of developing a servicing plan for the existing township.

Once complete, this infrastructure will be able to cater for an ultimate housing stock of 1,200 dwellings, made up of 450 dwellings (250 existing plus 200 infill) within the existing Kingston township, and 750 dwellings from the new KVL development. However, the capacity and serviceability will be delivered by multiple construction packages over a number of years.

These upgrades are partly funded by QLDC utilising an interest free loan from the Housing Infrastructure Fund. Debt will then be recovered through development contributions and targeted rates that are apportioned across the properties serviced by the new infrastructure.

Delivery of Three Waters infrastructure in Kingston will include the following:

Water supply:

• Deep bore water source (bore and headworks already constructed).
• Water Treatment Plant and storage reservoirs located on Glen Nevis Station.
• Bulk supply main.

Stormwater:

• Large diameter stormwater conveyance pipe along Oxford Street from the new housing development to Lake Whakatipu, including special soakage outlet.
• Medium diameter stormwater conveyance pipe along Shropshire Street from the new housing development to Lake Whakatipu, including special soakage outlet.
• Stormwater upgrades and/or conveyance at the western end of Kingston.

Wastewater:

• Wastewater Treatment Plant (WWTP): including associated pond, mechanical plant, buildings, equipment, and site facilities located on Kingston Station.
• Land Treatment Area: where the treated effluent from the WWTP gets discharged to continue the treatment process located on Kingston Station.
• Wastewater pumpstation on the corner of Oxford of Dorset Street and a rising main to the WWTP.

Friday 17 January 2025:

Work on water supply infrastructure will resume on Monday 20 January, with crews working along the shoulder of SH6 and up to Glen Nevis Station Road.

Find out more in the Where are we at? section below.

As with any large construction project, there will be some disruption while work is undertaken. This is likely to include noise, vibration, and construction machinery movements in the area, especially along Kent Street and Oxford Street.

Work to deliver this infrastructure will be staged, starting with associated water supply pipework through Kingston and the new water treatment plant, followed by stormwater improvements for the township, and then construction of the wastewater treatment plant.

Water supply works on SH6:

Crews finished installing the new bulk water supply main (water pipes) along the south side of Kent Street in Kingston at the end of last year.

Temporary stop/go is now operating at the intersection of Kent Street and SH6 while trenching occurs close to the road. This will be removed when work shifts further into the shoulder of the highway from around Monday 3 February - a temporary speed limit will remain in place along a small section of SH6 to help keep crews and drivers safe.

Please take extra care around the intersection of Kent Street and SH6, as this is a very busy area. Our teams on site are working as quickly as possible to get out of the way and to reinstate both lanes of the highway.

Stormwater works on Oxford Street:

Investigations for upcoming stormwater works where completed at the end of 2024, and we're now working with Wilson Contractors to finalise their timeframes for construction the new stormwater gallery outlet structure at the lake end of Oxford Street, and a large-diameter stormwater pipe running the length of Oxford Street.

We'll share what residents in Kingston can expect as part of these works as soon as possible.

Crews carrying out these works will ensure resident and pedestrian access is maintained, and any changes or potential disruptions will be widely communicated in advance to the Kingston community.

We’ll also ensure contractors delivering these works minimise as much disruption as they can and take resident and business needs into account where possible.

Work package one:

This includes establishing the new water treatment plant and reservoir on Glen Nevis Station, and a new bulk supply main running along Kent Street up to its intersection with Oxford Street.

Fulton Hogan took possession onsite on Monday 16 September 2024.

In October, crews will start with installation of the new bulk supply main (water pipes) along the south side of Kent Street. This work will start at the intersection of Kent and Oxford Street and move east towards State Highway 6, as crews try to complete as much of the disruptive work as possible before Christmas this year.

In the new year, crews will install water pipes alongside SH6 and up Glen Nevis Station Road, working on the new water treatment plant and reservoir at the same time.

All water supply improvements, including pipes along SH6 and Glen Nevis Station Road and the new water treatment plant, are expected to take just over a year to complete.

Work package two:

This includes the extension of the new bulk supply main from Kent Street to the Kingston Village subdivision, and construction of a large-diameter stormwater pipe along the length of Oxford Street.

We estimate this work will begin in the latter half of 2024 and will take 12 months to complete.

Work package three:

The wastewater component of these upgrades is currently in the detailed design phase.

We estimate this work will begin in the first half of 2025 and will take 18 months to complete.

We've launched a newsletter on the Kingston three waters upgrades, which aims to:

• Share more information about the project
• Provide updates on work happening in Kingston, and what's coming up
• Provide advanced warning of any potential disruption residents should expect
