Developed in Australia as a grey water diverter to help combat drought and water restrictions, the G-Flow grey water diversion system has also been used in many other different applications such as a drainage sump pump station, and even as a rainwater diverter. 


    Maybe used as a Drainage Pump Sump station
    Where part of the house or garden is flooded due to inadequate drainage, the G-flow has also been used as a pump station to shift the excess water out of the flooded area. The G-Flow incorporates the below ground housing as well as the drainage sump pump and can be buried up to its lid cover, thus making it an economical, aesthetic, and handy little automatic pump station. The pump automatically activated by a float switch when the water level in the tank reaches a predetermined level.

    Maybe used as a Rainwater Diverter 
    In many places around the world rainwater is captured from roof areas and stored in large rainwater tanks for use in and out of the house at a later stage. The larger the roof catchment area the more water can be captured and stored specially during short summer rainfall events. The G-Flow has been used when building configurations do not allow part or all of the roof area to drain by gravity into the main storage tank. The G-flow has also been successfully used to capture and transfer the water originating from a nearby shed or garage roof area back into the main rainwater tank positioned further away.
