A Christchurch City Councillor is strongly opposing the application by a Chinese owned bottling company to take 1.5 billion litres of water from a deep aquifer - saying it could threaten the city's drinking supply.
Ocean Cloud Water owns an existing 33-metre deep bore in the northern suburb of Belfast, from which it is extracting and bottling 4.3 million litres of water a day.
It has now applied to the Environment Canterbury for permission to extract water from a 186-metre deep bore at the plant so it can sell it abroad.
Vicki Buck the former mayor of Christchurch and chair of the Council's Innovation and Sustainability Committee, says this could compromise Christchurch's water supply.
Kathryn also talks with Steve Lowndes, Chair of Environment Canterbury.
