Water conservation

Water use in our homes increases in summer. For example, if you leave the sprinkler on for an hour, you’ll 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.

How much water do we use?
