Advantages of grey water recycling:
- Patented design guarantees safety
- Reduction of drinking water consumption by up to 70% by the combined use of rainwater and treated grey water
- Particularly efficient for premises with high water consumption and small rainwater collection area
- High operational safety and low operating costs thanks to intelligent control
- Compact design and underground installation, requiring no extra space in the house
- No noise in the building
- Suitable for remote control
* at 330 days per year production; ** at € 5,- water costs (Drinking water supply and waste water costs combined)

Principle components and connections for a 500l/day system
This layout has been designed as a 3 tank system with identical 500l tanks sized 1.650 mm height and 650mm diameter. Please note that the first tank works in this configuration as a buffer tank to handle a high inflow as it happens in the peak hours morning and evenings. To assist an initial purifiaction process the buffer tank (1st tank on the left) has been equipped with an additional active aeration. The control unit has been adapted to handle an extra component. The main benefit is that we can achieve a higher recycling rate by simply adding a buffer tank.
Larger systems for grey water recycling are available upon request. The capacity of 6m³/d of recycled grey water is the recommended maximum limit for preconfigured systems incl. all tanks ex Germany. For the export of grey water recycling systems a detailled training and installation is strongly recommended since local materials like tanks could be used.
Any systems larger then 10m³/d capacity requires a detailled planning process.
