Property and infrastructure general manager Tony Avery said the council had provided an updated drinking water safety plan and isolation plan for the plant to water services regulator Taumata Arowai.
“We began flushing the supply from Kelvin Heights yesterday morning in addition to continued monitoring and sampling. Initial results after flushing should be back on Wednesday,” Avery said.
“Assuming the results are clear, in line with our expectations, we will then be in a position to agree ending the boil-water notice for those residents and businesses served by this particular local supply.”
The notice would remain in place for all other affected parts of Queenstown and everyone in the district should maintain good hand hygiene to minimise the risk of the gastro bug spreading, he said.
“There has been a massive effort from council staff and contractors to get to this point. I would like to thank everyone involved as we continue our work to meet the requirements of Taumata Arowai’s order.
“We will keep updating the community about when we expect to lift the boil-water notice for everyone.”
No variation of the compliance order was required at this stage, he said.
Last week, the council confirmed it had secured UV disinfection equipment to provide a temporary barrier against cryptosporidium at the Two Mile plant, with a current installation timeframe of December 8.
