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.

Crews continue making great progress to install the new bulk water supply main along the south side of Kent Street in Kingston.

They're currently trenching near Kent Street's intersection with State Highway 6. 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 Kent Street underway:

Crews continue making great progress to install a new bulk water supply main (water pipes) along the south side of Kent Street in Kingston. This work started at the intersection of Kent and Oxford Street and is moving east towards State Highway 6 (SH6), as crews try to complete as much of this work as possible before Christmas this year.

The following temporary changes to road layouts are in place:

• Sections of Kent Street will be reduced to one lane under a priority give way system as work progresses from the intersection with Oxford Street towards SH6.
• Stop/go is operating on SH6 near Kent Street until Friday 22 November 2024. A temporary speed limit of 30kmph is in place when heading past the town.

Crews will monitor traffic to minimise as much delay as possible and to avoid any queuing of vehicles on SH6.

Future works:

Next up, crews will be reinstating asphalt on parts of Kent Street and preparing for trench works that will cross SH6 from Monday 25 November through to Friday 29 November.

We're expecting actual trenching across SH6 to take place between Monday 2 December and Friday 6 December, but will confirm these details as soon as possible.

Both weeks of work will require stop/go continuing to operate on SH6 and Kent Street.

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
