Nov - 2006 RainBank by Davey
Water supply is one of the most talked about topics across the nation. We can no longer afford to waste a single drop of water. Davey, a leading manufacturer of pumps and pressure systems, has identified this problem and developed RainBank® - an automatic controller for rainwater harvesting.
RainBank offers the flexibility of being incorporated into new homes or retrofitted into existing properties.
What does it do?
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.

- When a toilet is flushed or a washing-machine begins to fill the RainBank system detects this demand and automatically checks to see if there is sufficient water in the rainwater storage tank.
- If there is sufficient rainwater then RainBank switches the supply to this source and completes the demand cycle. Once the demand cycle is complete RainBank automatically switches off.
- 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 backup.
Water Saving - RainBank allows households in metropolitan and regional areas to replace up to 40% of their drinking-quality water usage with rainwater. Seamless and Convenient - RainBank does the thinking for you by automatically switching the water source from the domestic mains to the rainwater supply stored in the tank whenever a toilet is flushed or a washing machine used. If the rainwater supply is depleted at any time or in the case of a power failure, RainBank automatically supplies mains water as the backup.
Environmentally Friendly - RainBank only operates the pump to pressurise the rainwater when required. Energy costs are saved as there is no double-handling or re-pressurising of the mains water. Daily power consumption figures for a pump and RainBank system supplying toilet cisterns in a three-person dwelling are the equivalent to the operation of: - A reverse-cycle 2400W air-conditioner for 3 minutes a day - A 2400W clothes-dryer for 3 minutes a day - A 700W vacuum cleaner for 10 minutes a day - A 600W washing machine for 11 minutes a day - A 270W TV or computer for 30 minutes a day
RainBank also has a built-in backflow protectionvalve to ensure that there is no risk of backflow from the rainwater storage tank into the mains system, thereby preventing contamination of the mains water supply.
Easy to Install - RainBank can be incorporated into the design of a new home or retrofitted to existing properties. It is easy to install as either a complete system of pump and controller, or as a controller added to an existing pressure pump and tank installation. It is normally mounted on top of the pump; however, its design also allows remote mounting onto a wall or other nearby location.

Commercial Rainwater Harvesting
Case Study
Case Study
In 2005 Davey Water Products successfully applied for a Community Water Grant (CWG) from the Federal Government for assistance with the installation of a rainwater harvesting system to provide an alternative water source to their Scoresby factory paint line and toilets. The Community Water Grants projects funding announcements were made in celebration of World Water Day and will enable local projects to ensure a sustainable and water-wise future. Thanks to the support of suppliers, members of Government and members of the Davey team, Davey’s project will save an estimated 3 million litres of water a year and will also showcase rainwater harvesting, using RainBank in an industrial setting.
Water run-off from large factory roofs provides an excellent alternative water source which can be substituted for potable water in factory processes and human services.
Davey will install 150,000 litres of storage in three above ground polyethylene rainwater tanks. The water will be delivered to the metal powder coating pre-treatment line with a new VM series vertical multistage pump set.
