Kinloch Water Treatment Plant
Project overview
A new Water Treatment Plant (WTP) is being built in Kinloch while the water pipe network in the community is also being upgraded.
The project has a budget of $8.5 million allocated in the Long Term Plan and once completed it will produce 3,500 cubic metres of drinking water per day, with the opportunity to easily upgrade this to 5,000 cubic metres per day.
Kinloch is a growing community and the new plant will help meet rising demand and also make the water supply there much more resilient.
Work on upgrading water pipes in Kinloch is also included in the project, with a total of 9.2 kilometres of new pipe to be installed by Camex Civil. Construction of the new WTP is scheduled for completion in mid-2024.

Project updates
JANUARY 2023: Work underway on new Kinloch water treatment plant
Work on a new water treatment plant for Kinloch is underway following a site blessing by hapū leaders on Monday.
The new plant is the first project in a wider programme of water treatment plant upgrades around the lake, with Omori, Motuoapa, and Hatepe to follow.
Project manager Elijah May says the project has a budget of $8.5 million allocated in the Long Term Plan and once completed it will produce 3,500 cubic metres of drinking water per day, with the opportunity to easily upgrade this to 5000 cubic metres per day.
“Kinloch is a growing community and the new plant will help meet rising demand and also make the water supply there much more resilient,” Mr May says.
The project is a design and build, undertaken by Marshall Projects and Pall Corporation, designed and constructed to be operable after a significant seismic event, with the building foundation constructed using large deep driven piles throughout the building footprint.
“The new plant will be a membrane style system, much like the Taupō water treatment plant on Lake Terrace, and construction is scheduled for completion in early 2024.”
