Government water regulator, Taumata Arowai, has advised it will decline Christchurch City Council’s first chlorine exemption applications, with the Council today describing the news as “a bitter disappointment”.
“My colleagues and I are outraged to learn of this decision and know many Christchurch residents will feel the same,” said Mayor, Phil Mauger.
“The exemptions have always been presented to us as something we would be able to achieve but today we’ve been advised that the exemption has been declined and the water supply has to be chlorinated to be compliant.”
The remaining 20% of the Christchurch and Banks Peninsula water supply is now required to be chlorinated, which will take a number of weeks, he said.
The Council always intended to apply for exemptions on a zone-by-zone basis and started this process in October 2022 with an application for Brooklands-Kainga, as this water zone was identified as having the best chance of getting an exemption due to the quality of infrastructure and groundwater, Council said in a statement.
The Water Services Act 2021 makes it mandatory for owners of reticulated water supplies to add a residual disinfectant – chlorine – to the water unless they obtain an exemption from Taumata Arowai.
“They have dashed our hopes of this today,” Mayor Mauger said.
The Mayor has today written to Taumata Arowai requesting the Chief Executive attend a public Council meeting to explain their position regarding exemptions.
“While we’re being forced to chlorinate our water supply we will continue to fight and advocate for the people of Christchurch,” he says.
“We’ve heard that if we want to gain exemptions for any of our water supply zones, we’ll need to go over and above the standards set out by the Government. To achieve this, we’d have to make substantial upgrades to our water supply network at the cost of millions of dollars.
“This would be a huge investment considering its unlikely that we would ever be granted an exemption for the city. I feel as a Council we have been led up the garden path by Taumata Arowai,” the Mayor said.
