Our Council is spending nearly $16 million over the next three years to upgrade 10 water treatment facilities across our district.

"We're ramping up what we need to do to keep improving the quality of our drinking water supplies, as we take actions after lessons learned from what happened in Havelock North," says our Council's Project Manager, Andrew Boden.

A Government inquiry was sparked by the 2016 Havelock North gastro outbreak, which was linked to four deaths, and called for a major overhaul of water supplies, including mandatory treatment.

"This New Zealand Ministry of Health’s short cartoon video is a really good promotion showing how councils sample and monitor drinking water, methods of drinking water supply treatments, and how outbreaks can happen in drinking-water supplies," says Mr Boden.

Whitianga's new water treatment plant at Moewai Rd was our first plant to be upgraded, marking an important milestone in our drinking water standards project - Tautiaki Wai Māori.

Our contractors, Masons Engineers built the new $2.8 million water treatment facility on the same site as the old one on Moewai Road. This new plant has the latest technology and methodologies for treating our water including Evoca supplied membrane units, new filtration, dosing and monitoring equipment.

Masons Engineers are now underway with the Tairua upgrade and expect it to be completed early next year, with Pauanui also scheduled to start this month and finish late 2020. The new water treatment plant works at these two sites involve new stand-alone buildings, water and chemical storage tanks, along with  civil works including earthmoving, roading and fencing. The plants will also have new machinery, telemetry and control and chemical dosing systems.

Following on from these two sites, the next town on the upgrade schedule is Coromandel Town, with the remaining treatment plants at Whangamata, Onemana, Matarangi, then Hahei following after.

All of these upgrades will ensure our drinking water quality complies with the current NZ Drinking Water standards.

The drinking water treatment plant at Thames was upgraded more recently than the other plants, and is not due for an upgrade as part of this project.
