Drinking water standards upgrade

Upgrade programme begins at our water treatment facilities

Work has started to upgrade our ten water treatment facilities across the Thames-Coromandel district.

The upgrades will ensure our drinking water quality complies with the 2005 (2008) NZ Drinking Water standards. For more information on our compliance with the government’s new testing regime see here.

Our Council continues to be proactive about what we need to do to keep improving the quality of our drinking water supplies and has budgeted $15.83 million in the 2018-2028 Long Term Plan for the upgrade programme, which will take three years through to June 2021.

Our Mayor Sandra Goudie says this is a significant investment to ensure compliance and that our communities benefit from improved quality of drinking water and public health.

The first plant to be upgraded is the Whitianga water treatment plant, where Mason Engineering is building a new $2.4M water treatment facility on the current site. .

Site works are due to start in the first week of October, 2018.

The upgrade schedule will continue to the water treatment facilities at Tairua and Pauanui over the next year. Whangamata and Onemana will be completed in year two, followed by Matarangi, Coromandel Town and Hahei.

Five of the drinking water plants, which treat river-supplied water, will use membrane filtration technology, the highest-quality treatment available for this type of water source. The Memcor brand membranes are being supplied by Evoqua Water Technologies. The other five drinking water plants will use filter/cartridge system for treating bore-supplied water.
