Developed in Australia 6 years ago as a GreyWater diverter to help combat drought and water restrictions, the G-Flow system, has also been used in many other different applications such as drainage sump pump station, and even rainwater diverter. This state of the art compact, economical and versatile system incorporates the following features:

As Grey Water Diverter:

With the cost of water constantly rising and water restrictions in place in many parts of the world, it make sense not to throw out the water that has been paid for and to reuse it to irrigate the household garden and trees. Today the G-flow system is widely used to filter and pump laundry, shower and basin water into irrigation systems for gardens. The system was originally designed for this specific application and carries the appropriate health and plumbing standards and certifications in countries such as USA, Canada, Australia, New Zealand & South Africa. Over 7,000 G-Flow Greywater diverter systems have been sold worldwide with remarkable plants and landscape outcome, as well as great water saving results (as much as 200,000 Liters or 50,000 Gallons per household per year). In addition the system has won several water saving awards in shows worldwide. Although most of the detergents today are biodegradable and environmentally friendly the use of low phosphorus and low salt detergents are recommended for improved long term results.

As 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.

As 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.
