Work is well underway with our programme to upgrade ten water treatment facilities across our district.

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.

Latest update June 2020:


It's going to be another big year for our $16 million drinking water standards project - Tautiaki Wai Māori – with a second, brand new treatment facility in Tairua (pictured above). Installation was delayed due to COVID-19 however we expect to have an official opening in July 2020. 

This is year two of a three-year project to upgrade 10 water treatment facilities across our district as we keep improving the quality of our drinking water supplies.

Our contractors Masons Engineers have completed the new plant on Tairua’s Hinemoa Tce, fitting it out with the latest technology and methodologies for treating our water including Evoca-supplied membrane units, new filtration, dosing and monitoring equipment.

Also underway is the new plant in Pauanui. The erection of the roof steelwork is currently taking place and the commissioning of the plant should be completed in September 2020. Like Tairua, this water treatment plant involves 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.

Meanwhile, civil works have started on-site for the fourth new plant in Coromandel Town and is expected to be finished in May 2021.

The Building Consent application was submitted in June 2020 for the Beverley Hills (Whangamata) upgrade and we expect that construction work will start on site towards the end of July 2020, with the plant handed over in June 2021.

Planning is underway for the remaining upgrades: Wentworth Valley (Whangamata), Moana Point (Whangamata), Onemana, Matarangi and Hahei (in that order).

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.

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.

"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 delivery manager Andrew Boden.

"This is a large and important project or our Council and we look forward to making good progress and introducing more new plants this year," Mr Boden says.
