Davey RainBank Rainwater Harvester
The Davey 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 households drinking water supply (which is normally used in these applications), thereby helping to conserve Australias precious water resources.
Kit Includes:
- RainBank_
- Pump
- Water Level Sensor
- Connectors
How RainBank_ Works
When a toilet is flushed or a washing machine begins to fill, the RainBank_ system detects this deman and automatically checks to see if sufficient water can be found in the rainwater storage tank. If sufficient rainwater is available, the RainBank_ switches the supply to this source and completes the deman cycle. At the completion of this deman cycle, the RainBank_ automatically switches off, thus saving energy.
If the rainwater supply is depleted at any time during a demand cycle (or prior to a demand cycle), RainBank_ provides mains water to fulfil the demand. In the case of a power failure, RainBank_ automatically supplies mains water as the back-up.
