Christchurch residents who use lots of water may have to pay for the extra they use. The city council wants to charge households using more than 700 litres of water a day, well above the daily average of 540 litres. Residents with pools, and large gardens would have to pay up. The proposal is part of the city council's draft long-term plan, released today. Christchurch deputy mayor and councillor Andrew Turner spoke to Susie Ferguson.
