Where do we use our water?

In the home, water use increases dramatically with the onset of summer.  For example, if you leave the sprinkler on for an hour you will use 1000 litres of water.

A 2007 study by BRANZ, a research and information company providing services for the building industry monitored the water use from 12 homes on the Kāpiti Coast. The following figures are averages from this study.
