Dunedin City Council boil water notice update
3.10pm, Tuesday, 15 August 2017

A boil water notice will remain in place for parts of central and north Dunedin until at least late Friday.

Dunedin City Council Chief Executive Officer Sue Bidrose says untreated water began entering the treated water supply yesterday afternoon.

Staff had needed to lower the level of the Ross Creek reservoir to assist with the dam refurbishment project there. The staff had checked DCC plans and maps which didn’t show any connection from these valves into the reticulated water supply. It was understood any such connections had been decommissioned some 30 years ago. However, this has been proven to be incorrect. This resulted in the untreated water entering the treated supply.

“As soon as the DCC became aware of the issue, we shut down the valve and immediately issued a boil water notice,” Dr Bidrose says.

The DCC issued the boil water notice at 10am today. Information was distributed to the public via news media, social media, phone calls and emails to businesses, organisations and education providers, and through stakeholder networks.

There about 1720 residential properties and 825 commercial properties in the affected area, which includes the CBD, North Dunedin, Leith Valley, Woodhaugh, and the Warehouse Precinct.

Dr Bidrose says that the valve was turned off at 10am today to ensure to no new untreated water entered the system. Contractors have opened hydrants throughout the affected area to discharge untreated water.

If you’re in an affected area please flush run your taps for 10-15 minutes. This will flush the water and will help with the cleaning process.

“We now need to ensure at least three clear days of testing, plus 24 hours, before the boil water notice can be lifted,” she says.

“We have therefore organised for water tankers to have clean drinking water available for people at several locations in the affected area.”

The Dunedin Civil Defence Emergency Operations Centre activated this morning to co-ordinate the response to the situation.
