Ecology park on the banks of Zeekoe Vlei has become an icon of sustainability. Rainwater from the roof is filtered before being sent to the water tanks. From the water tanks the water is pumped, under pressure, into the building and used for showering and washing hands. This washwater (greywater) is then sent to the greywater recycling system where it is reused to flush toilets. Only then does the water enter the sewer.
