Residents and businesses in the Tasman town of Richmond are being told to boil their water because of ecoli contamination.
The Tasman District Council said it was a precautionary measure because of an extremely low level detected in a bore on the Richmond water scheme.
The boil water notice has immediate effect and covers the Richmond urban area.
It was put in place at the request of public health officials.
The testing needs three clear readings before the notice can be lifted. It will remain in force until Monday when an update on the situation will be given.
The notice affects all residential, commercial and service based properties on the scheme.
The council said while the source of contamination has now been isolated, the water from the Richmond water scheme has been compromised. It is therefore recommended that as a precaution, drinking water needs to be boiled.
WHAT TO DO:
Richmond residents are advised to boil all water for at least one minute if it is to be used for drinking, food preparation, utensil washing, washing teeth, pets or ice.
