Ms Maria Graham:

To address the same point, obviously there is an efficiency target. Regarding its implementation, metering has given rise to issues such as identifying leakage. The benefits of metering are more long term than on a year by year basis. If money is being saved by identifying leaks and reducing consumption, the rate at which capacity and plants must be built is deferred into the future. One is, therefore, comparing a short-term issue with a long-term one.
