Boil water notice lifted

The boil water notice affecting Christchurch’s Rawhiti water supply zone has been lifted.

Christchurch City Council has had three clear days of sampling from the wider Rawhiti zone and isolated the source of the issue so residents in the New Brighton, Burwood, Wainoni, Aranui and Southshore areas no longer need to boil water. 

Investigations are still ongoing but we believe it was due to work recently undertaken on the network. The Council has done significant sampling throughout the zone and we are now confident the contamination is isolated to a small area.  

Approximately 20 properties will need to keep boiling their water. We will be communicating with these residents directly. 

The notice was put in place on Saturday after regular testing detected total coliforms are a group of bacteria commonly found in the environment. Their presence in the water network serves as an indicator of potential contamination and the possible existence of harmful pathogens.
