Study Session 11  Efficient Use of Water


Efficient use of water means using only the amount of water required for a given task without any water going to waste. Using water efficiently results in water being conserved. It also results in savings in energy and chemical use, since less treated water has to be put into the water distribution system. In this study session you will look at efficiency in water use, and also consider alternative sources of water (such as rainwater and treated sewage) for non-drinking purposes such as irrigation.
