SR159 Water End-use and Efficiency Project (WEEP) (2007)

Twelve homes on the Kapiti Coast are being monitored to find out where the water is used. This report includes monitoring data and analysis of the winter and summer period, as well as a summary of the methods and tests that have been conducted in order to derive an end use monitoring technique.

By analysing water use at an end use level, it is possible to identify the areas that would yield the greatest results when conducting a retrofit.

The largest water savings could be achieved by installing low-flow shower heads and water-efficient washing machines. High savings in mains water use can be accomplished by installing a greywater system or rain tank.
