The boil water notice issued for properties in Bishopdale and Springlea is being extended to three days as a precautionary measure.

New water quality testing today confirmed that previously detected levels of E. coli are no longer present within the drinking water supply. However, following further discussions with Taumata Arowai (Drinking Water Regulator), Council is extending this notice until Friday evening while further testing is undertaken to verify there is no longer an issue. This notice effects approximately 170 properties within the Nelson area.

Nelmac is hand delivering letters to all properties that received a letter yesterday.

It is expected that this notice will be in place until Friday evening, Council will notify residents via a hand delivered letter when the water is again safe for consumption.

This affects properties on Vista Drive, Bills Drive, the lower half of Bishopdale Avenue (90 -110 on the even side, 103 – 109 on the odd side), Marie Place, and Potteries Way in Bishopdale, and Springlea Heights, Farleigh Street, Devenish Place, Komako Way, Koura Road, Bristol Lane, and 40 Frenchay Place in Springlea.

These results are highly unexpected, as the Nelson drinking water supply is treated at the Water Treatment Plant using ultra filtration membranes and the water reticulation is chlorinated for added protection.

Residents have been advised to use boiled water for drinking, preparing food, cooking, making up infant formula, handwashing, and cleaning teeth.

More information on what should be boiled and other forms of treatment can be found on the Taumata Arowai website at

Once the boil water notice is lifted, it is recommended you run your taps with cold water for five minutes and flush any appliances. If you've been away during the notice, run your taps for 15 minutes to clear old water.
