Annual Water Consumption

A graph of annual water consumption from 2010-2017The stacked bar chart displayed on this page shows our annual water consumption in kilolitres (kL)  for the years 2010 to 2018. Each year's consumption data are divided into the following different water sources: municipal water supply, surface water, rainwater collected and waste water from another organisation.

The chart highlights that municipal water consumption which represents the major water source, peaked in 2015 and has been decreasing since. Metering of surface water use was implemented in 2016. Rainwater collected is estimated because rainwater consumption is not currently metered.
