Structural + Geotechnical + Civil Push to upgrade water facilities The new Kinloch plant is capable of producing 5,000 cubic metres per day. T T Sue Russell “It has been a busy and very productive time for us as we’ve progressed steadily through some significant works and I’m pleased to say the work has gone very well.” There’s been a real push, on the part of Taupō District Council, to breathe new life into a number of outlying water treatment plants, serving the smaller communities in the district, something Andy Taylor says is being welcomed by residents in these smaller places. “It’s just as important in these settlements to have resilient water treatment infrastructure in place, so Council has committed funds through its Long-term Plan, to replace, upgrade or expand what currently exists,” Andy says. “It has been a busy and very productive time for us as we’ve progressed steadily through some significant works and I’m pleased to say the work has gone very well,” he says. Among these works are four projects which promise to bring significant future-proofing values to their respective communities. A Kinloch project involved construction of a new Water Treatment Plant (WTP), alongside upgrading of the water pipe network. As a growing community the new plant will help meet rising demand and also make the water supply there more resilient. “The plant has been built on a firm footing to withstand any seismic activity, with 21m-long steel piles topped with a 600mm reinforced concrete pad, making the plant very resilient and ensuring continuation of service.” The new plant is capable of producing 5,000 cubic metres per day and has been constructed by contractor Marshall Projects. Along with the new facility a total of 9.2 km of new water network pipes were installed by Camex Civil. At Omori, a new water treatment plant has also been built serving the Omori, Pukawa and Kuratau communities. This plant was officially opened in May 2026. Capable of producing two million litres of drinking water each day the possibility of future expansion has been engineered in. “This is a major upgrade from the treatment process in place at the previous plant, with state-of-the-art membrane filtration system, UV treatment and monitoring equipment installed, and if there’s no power, a large permanent backup generator can run the plant.” This project was funded by district-wide water rates, costing $8.6 million. Works have commenced on the new Motuoapa Water Treatment Plant located on Parekaawa Drive. The state-of-the-art membrane style plant will have an added treatment process to address the natural arsenic levels found in Lake Taupō. With a capacity to treat over 1200 cubic metres of water at peak production, the Motuoapa WTP has a budget of $9.5million. Completion is due later this year. “This plant will provide Motuoapa residents with a higher degree of protection for their drinking water supply and has been designed to meet planned growth in the area.” And the final significant project, also in progress, is at Hatepe village, where a similar style membrane water treatment plant is currently in its design phase, with construction expected to commence this year. Budget at Hatepe is $6M and TDC are targeting project completion by mid 2027. In addition to these four membrane water treatment plant upgrades, TDC have completed new plant construction projects at six smaller communities across the District, including Atiamuri, River Road, Tirohanga, Waihaha, Whakamaru and Whareroa. The upgrades at these sites involved new treatment buildings that were designed and built offsite, transported to site, commissioned and put into operation. Each new plant building included UV disinfection, pH correction and residual disinfection treatment processes. The upgrades at these sites will deliver numerous benefits to the small communities they serve, including improved water quality and increased supply reliability.. These 10 projects, scattered across a significant area within the Taupō District Council’s region, will mean Water Treatment infrastructure to support future growth has well and truly been factored in. “We’ve invested to upgrade and deliver new technologies bringing them up to the standard of the best available in the country. It’s something everyone connected with these projects is very proud of.” Taupō mayor John Funnell at the opening of the new water treatment plant at Omori in May. The plant serves the Omori, Pukawa and Kuratau communities.
