After testing positive for E.coli on Friday, the boil water notice on the town’s water supply has been lifted after three days of negative tests.

A boil water notice on Carterton’s town supply has been lifted following three consecutive days of clear tests.
A boil water notice was placed over the town on Friday afternoon when E.coli was detected in the supply.
Regional Public Health gave permission to lift the notice at 4.40pm on Monday.
The urban water supply pipes were flushed and the water source was switched over from the bores to the Kaipatangata Stream, which meant the water was fine to drink without having to be boiled first, a Carterton District Council spokesman said.

If there was heavy rain in the next two days, it could cause cloudiness in the water and the council would need to switch back to the bores for urban supply, which might mean imposing the boil water notice again.
Council infrastructure, services and regulatory manager Dave Gittings said the water was safe to drink, so the council didnt want to have the boil water notice in force longer than necessary.
Because weve switched to the Kaipatangata, we can safely lift the notice.
He said the council was yet to identify a definitive source of the E.coli reading, so was cleaning the tanks associated with the bores and retesting the water.
This means if theres heavy rain over the next few days, and we have to switch back to the bores, theres a small chance we may need to go back to a boil water notice as we wouldnt have finished cleaning and retesting yet.
Mayor Greg Lang thanked the community and businesses for their patience.
I know this has been an inconvenience to many people, but Im really impressed with how people took this in their stride and helped the council get the message out, he said.
