Water is supplied to the centre through rainwater harvested in reservoirs. Some of this is used directly, for example to flush toilets or water the gardens. For drinking water however, the water is treated through a slow sand filter and a UV filter. They also try and conserve water around the centre, using low flush toilets or waterless urinals, water saving taps, etc. Further shown, is how the water cycle can be used to generate electricity. For example, turbines are installed where the water flows downhill.
