In the event Watercare secures approval to take an additional 150 million litres a day from the Waikato River, it will need $160 million for a new permanent water treatment plant at Tuakau, Stuff reports. Watercare is currently working on the finishing touches of a new $145 million temporary water treatment plant in Tuakau, aimed at providing Auckland with an extra 50 million litres a day from the Waikato River. The new facility is expected to go live in June. It was included in a $224 million package approved by the Auckland Council in 2020 to boost the city’s water supply as part of its drought recovery response.
