    Onga WaterSwitch is a fantastic new innovative rainwater harvesting product to help you save water around your home. WaterSwitch is designed as an automatic rainwater controller that switches between mains supply and tank water. Onga WaterSwitch, used in conjunction with a Water tank and an ever reliable and reputable Onga Pump, allows a conventional household to re-use rainwater for a variety of everyday tasks. Use rainwater for toilets, washing machines, garden sprinklers, washing the car etc. Each time you use rainwater you’re leaving water in your city’s catchments for use later on. More importantly it also leaves space in your rainwater tank to store more water next time it rains. That’s called Rainwater Harvesting.

    How does WaterSwitch work?

    WaterSwitch is a fully automatic device that has the ability to detect the level of water inside the tank, it can ensure a seamless supply of water to the home without interruption. When the tank is filled during rainfall, the WaterSwitch detects the level of water in the tank rising off the bottom, and automatically diverts demand on the system to be supplied with the available rainwater. When the water level in the tanks falls below a specified level, the WaterSwitch seamlessly switches all demands on the system over to main water temporarily, to ensure that supply is not interrupted.  This ensure that supply of water is never interrupted and that you are maximising the use of rainwater therefore maximising your savings.
