How it works
Rainwater harvesting is the ability to capture grey/nonpotable water at the point where it falls and substitute it for mains water, in non-potable applications. The RAINstar collects the run-off from the roof area, via the sealed gutters. The flow is then passed through a series of filters. The first is the Leaf Filter, which removes leaves, twigs and other light debris. The water flows down into the underground concrete storage tank, through a calmed inlet.
Water is then pumped up, via a pressure switch & buffer vessel, to a Header Tank. This is then gravity fed into
separate pipework for non-potable applications - toilets, washing machines, outside tap. Enroute to the header tank, the harvested rainwater passes through two further filters - the final filter removing the fine sediment, down to 5 microns. In times of heavy rainfall, the RAINstar system is designed to overflow to storm drain via a trapped overflow syphon. If the tank runs empty, the system automatically switches over to the mains water supply. It’s that simple.
