Automatic Rainwater
Harvesting
RainBank is an automatic controller for rainwater harvesting. Incorporated into the design of new homes or retrofitted to existing properties, RainBank controls the water supply for toilet or laundry applications by automatically switching the water source from the domestic mains to rainwater when a demand is sensed and rainwater is available in the storage tank.
RainBank is the first product to use rainwater as the water supply for toilet and laundry applications in the metropolitan area and control it automatically. It can save up to 40% of a household's drinking water supply which is normally used in these applications, thereby helping conserve Australia's precious water resources.
Daily power consumption for a pump and RainBank system supplying toilet cisterns in a three-person dwelling are equivalent to a 2400W air conditioner or clothes dryer operating for 3 minutes a day or a 270W television or computer operating for 30 minutes a day.
RainBank also has a built-in backflow protection valve to ensure there is no risk of backflow from the rainwater storage tank into the mains system, thereby preventing contamination of the mains water supply.
The RainBank will help achieve the BASIX score and 5 star rating on new homes.
