Product Description


The 4000L Rainbank Rainwater Harvesting System is a complete concrete system.

How Does It Work:

The rainwater from the roof is channelled through the downpipes into a vortex filter which eliminates leaves and other debris before entering the tank through a calmed inlet. This water is then pumped on demand into a header tank in the house or garage for distribution to selected applications - toilets, dishwashers etc. In the event of low water level during a long dry spell, the pump will automatically switch off and the header tank will fill from the mains water until rainfall resumes.

The purchase of this rainwater harvesting system comes with delivery, supply, installation and commissioning. We don't simply drop it on site. Our staff will be on hand during installation with good advice borne of years of experience to ensure that your system is perfectly installed.
