The average monthly consumption per meter per day in 2018 was 368 litres which was 3.1% higher than the 2017 figure of 357 litres (see Figure 29.1). In contrast to average consumption, the median consumption per meter per day in 2018 of 255 litres was the same as in 2017. Median consumption reflects typical levels of consumption more than average consumption as the median is less affected by meters with very high levels of water use due to leaks.
