Queenstown Lakes District Council (QLDC) will begin proactively disinfecting all water supplies under its control before Christmas.
The move will see water supplies in Luggate and Glendhu Bay chlorinated over summer, as well as some areas near Queenstown.
Wanaka’s water already receives the treatment permanently, while Hawea remains under temporary chlorination after high coliform counts were detected in supplies earlier this year.
QLDC Chief Executive Mike Theelen said it would protect water quality during a period of heavy use.
“The proactive chlorination of these supplies is being done to ensure the water remains safe to drink across the district while the large increase in visitors to the region creates extra demand on the water network,” he said.
The water supplies will be chlorinated over summer, beginning by the end of this week (December 22), and Mr Theelen said a decision on whether it continues will be taken by QLDC early next year.
“Our staff will provide a report to Council on the risks, benefits and implications of how we can best protect the safety of all of our drinking water supplies, along with their recommendations as to how we can best achieve this.”
The news comes after Stage 2 of The Havelock North Drinking Water Inquiry, which called for a major overhaul of water supplies and strongly recommended mandatory treatment after it was estimated 5500 of the North Island town’s 14,000 residents became ill with campylobacteriosis.
It was also unable to rule out a link between the illnesses and three deaths.
