"No enthusiasm for Waimarino water scheme
The idea was to tap into one source of water – possibly at Karioi – for Ohakune and Raetihi, which at present have two separate supplies and treatment plants. This would also supply Rangataua as well as rural users such as market gardens.
“The Waimarino Water Scheme had the potential to increase economic output through both Tourism and Agriculture. It would have solved many problems,” reported Council chief executive Peter Till.
However, he said it was “likely to create many more” problems and that the risks were significant and the returns uncertain. It would have added around $500 per year to the average rates bill.
The Plains water scheme has been investigated since 2008 and for many years prior to that, a number of local residents had promoted extending the pipes to the separate springs that supply Ohakune and Raetihi.
In 2014 RDC commissioned GNS to report on water sources. GNS said ground water was less reliable in the District’s volcanic area and that springs move over time.
GNS recommended that deep ground water (bores) should be investigated.
The 30km pipe plus one treatment plant, plus agricultural storage dams would have cost an estimated $20 million
