How It Works
The Rainwater Harvesting Tank collects the run-off from the roof area through sealed gutters.
Before entering the tank the flow of water should pass through a series of filters which eliminate large particles such as leaves, twigs and other debris.
The filtered water now flows into the tank through a calmed inlet pipe.
The water is then pumped up via a pressure switch and buffer vessel to a header tank. From here it is distributed to all non-potable applications such as toilets, washing machines and outside taps.
During heavy rainfall the tank is designed to overflow to a storm drain.
If the tank runs dry the system can be designed to switch to the mains water supply.
