Christchurch City Council is urging residents and visitors to Duvauchelle to immediately reduce water use due to critically low water supply.

The treatment plant stopped working over the weekend due to the high level of rain resulting in turbid (murky) water that can’t be converted into drinking water. There may also be a leak contributing to water loss.

We have been bringing water tankers to the plant over the weekend and have now increased the number of tankers, but this still isn’t keeping up with demand.

Level 4 water restrictions are being put in place immediately to help manage the supply, which includes a total ban on outdoor water use.

Head of Three Waters Gavin Hutchison says residents and visitors should also stop using water for any non-essential activities.

“You can continue to use water for drinking, cooking and hygiene but please consider delaying non-essential washing and laundry,” says Mr Hutchison.

“Please let us know if you are aware of a leak or have seen something irregular or out of the ordinary that might suggest a leak. Please also let us know if you have significantly changed your water use or have noticed a change in usage elsewhere.”

“We’ve got contractors and staff in Duvauchelle looking for possible leaks but appreciate any information the community can provide, as it may help us resolve the issue more quickly.”

“Over the coming days we will be transporting water to the Duvauchelle water treatment plant to ensure a continued supply so you may notice tankers coming and going.”

“We’re working with our contractors to increase the number of tankers travelling to Duvauchelle with water.”

“Conserving water will help us continue to supply safe water to everyone in the Duvauchelle community.”

The Council will set up electronic roadside signage in the area. Residents are encouraged to share the message with their neighbours.
