However, there remain questions over how many years it may be before existing residents in the township can hook into it.
The Queenstown Lakes District Council is working with Kingston Village Ltd to deliver new water and wastewater plants, and a range of stormwater improvements, to support the developer’s 750 new residential sections, just south of the existing town.
Council property and infrastructure general manager Tony Avery said a "share of the delivery of the services" and costs had been arranged by the council and KVL.
The Otago Daily Times asked what the council’s share of the costs was, but a response was not received by deadline.
Mr Avery said the upgrades would be partly financed by an interest-free loan from the Housing Infrastructure Fund, with debt repaid through development contributions from KVL and targeted rates as and when new properties connected to the services in future.
While existing Kingston residents would eventually be able to connect to the infrastructure, Kingston Community Association (KCA) chairwoman Kimberley Marshall said there was no clarity or certainty around when that might happen.
The council advised existing properties would need to continue managing their own water and wastewater systems until it completed "further planning, design and financial analysis work" and engaged with the community as part of developing a servicing plan for the existing township, which Ms Marshall said was "growing almost daily".
"What’s quite evident is that there is going to be a reasonable amount of disruption for us as a community ... with no immediate benefit," she said.
"We know that the benefits for us are a long way down the track, being realistic.
"What we would really like, as a community, is some certainty ... realistic timeframes as to when it is actually going to [benefit] us ... and also costs."
The three-stage Three Waters upgrades, including a water treatment plant and reservoir on Glen Nevis Station and a wastewater treatment plant on Kingston Station, would begin about July and take at least three years to finish.
Ms Marshall said the KCA would form a subcommittee to focus on the upgrades to ensure the voice of the town’s residents was heard "as much as it possibly can be as things progress".
A case for a reticulated water and sewage scheme for Kingston was raised in 2003 when the Kingston 2020 plan was adopted, in which provision of adequate infrastructure was identified as a key issue.
It stalled, however, until a plan change rezoned 88ha of land in 2009 to enable KVL’s residential development.
As part of that, KVL was obliged to install water and sewerage systems for new subdivisions, thereby paying for the basic infrastructure, with the community required to meet some of the cost.
In 2016, the ODT reported given the cost burden of the user-pays system, which included the council buying or leasing land for a wastewater plant and disposal field, it was deemed too expensive for the community which, in 2018, was home to about 350 people.
