Do you want to collect rainwater and turn it into drinking water? Our rainwater system with drinking water treatment offers you an all-inclusive, worry-free package: It consists of a contaminant-free underground tank, a biological water filter, a high-performance pump, a reliable UV drinking water treatment system, and all necessary accessories. This system makes it easy and reliable to supply single-family homes, garden and vacation homes, tiny houses, construction trailers, or cabins with high-quality drinking water. The system is also used in industrial and commercial settings.
Please check with the
relevant authority (e.g., your local
health department) to see if additional municipal regulations apply to the operation
of such a system.

Feel free to use our rainwater calculator.Main components of the rainwater treatment system Underground tank/cistern 4,700 liters The rainwater tank is made of high-quality, environmentally friendly polyethylene and is 100% recyclable. The material is chemically inert—meaning it has no effect on the quality of the stored water. Compared to concrete or metal tanks, this cistern is significantly lighter and easier to handle. The GreenLife underground tank is 100% watertight. It is delivered ready for connection and pre-assembled: three connections for inlet, overflow, and supply line/empty pipe connection (rubber lip seal DN 110), e.g., KG pipe. The cistern includes a continuously height-adjustable leveling dome and a walkable safety plastic cover. The slip-resistant pattern on the safety cover depicts the “Flower of Life,” a popular decorative motif understood in many cultures as a symbol of cosmic order. We provide a 15-year warranty on the underground tank in accordance with our warranty terms and conditions. Fully Biological Water Filter Biovitor The low-maintenance rainwater filter we developed purifies your water without chemicals and achieves a high yield of top-quality rainwater. Unlike conventional filters, the Biovitor uses the same natural processes for biological self-purification as our local waterways. The Biovitor contains no wear parts, so you can rely on maintenance intervals of up to ten years. UV Drinking Water Treatment System The GreenLife water treatment system, with its compact design and low energy consumption, impresses with its high disinfection performance; treatment is carried out without chemicals. After purification using two sediment filters and one activated carbon filter, any remaining bacteria, germs, or viruses are rendered harmless through UV disinfection. The UV lamp requires minimal maintenance; it should be replaced after 10,000 operating hours (as disinfection performance decreases).
The system has a long service life. GUP 46 Clear Water Pressure Pump The high-quality, durable, and powerful GUP 46 submersible pressure pump delivers clear water to the desired locations in the house. As a multistage submersible pressure pump, it is primarily used in building services. A float switch acts as dry-run protection. All water-carrying parts of the pump are made of stainless steel.How the GreenLife Rainwater Treatment System with Underground Tank and Drinking Water Treatment Works Rainwater is directed from the available roof surfaces to the cistern (rainwater tank). Whenever possible, only roof runoff water should be used, as—unlike with courtyard and driveway surfaces—relatively low levels of contamination are expected. If leaves are expected, a gutter screen or similar leaf separator technology must be used. Once the rainwater reaches the cistern, the fully biological Biovitor rainwater filter ensures effective pre-filtration. As soon as a faucet is turned on at a connected outlet in the house, the vacuum water pump in the cistern starts up: The pre-filtered rainwater is transported by the pump to the drinking water treatment system. The rainwater to be treated first passes through two sediment filters (20 μm and 10 μm), then an activated carbon filter, and finally undergoes highly effective UV disinfection. The water is now safe to drink. For your own safety, water quality samples should be tested at regular intervals. The maximum treatment capacity of the drinking water treatment system is 2,000 liters per hour. For more information, see “Downloads” (above as a separate tab). Important Information and Technical Notes Underground tank system with Biovitor Install according to the installation instructions (see the "Downloads" tab).The underground tank is not drive-over in this configuration. Upon request, all underground tanks with a capacity of 2,200 liters or more can be retrofitted with our drive-over kit for passenger cars.When the tank is full, our infiltration cubes, infiltration blocks, or infiltration shafts offer good options for allowing overflowing rainwater to seep into the ground. Rainwater can also be directed in an environmentally friendly manner across the ground surface into an infiltration basin; this is the most eco-friendly option.Drinking Water Treatment UV 2000All components are pre-assembled on a mounting plate.The cartridges, including the filter cartridges of the three-stage filter, are pre-installed. An automatic switch with a check valve controls the pump as needed.Install the UV 2000 inside the building/utility room—not outdoors if there is a risk of frost.The UV lamp for UV disinfection has a service life of approximately 10,000 hours. The lamp can be turned off when you are away.The system requires 230 V / 50 Hz.For your own safety, the treated water should be checked at regular intervals.
Installation Instructions Underground Tank & BiovitorPlease follow the installation instructions: Read the instructions thoroughly and in their entirety before installing, connecting, and commissioning this product. Pay close attention to all safety instructions—failure to do so will void all warranty and guarantee claims. Pump, UV Drinking Water Treatment Operating Instructions for Pump GUP 46 Operating Instructions for UV Drinking Water Treatment Maintenance The entire system must be inspected regularly for leaks, cleanliness, and stability.
Maintenance of the underground tank system should be performed approximately every 10 years.
The special UV lamps should be replaced after 10,000 operating hours; otherwise, the disinfection rate will decrease. The filter cartridges for the sediment filter and the activated carbon filter should be replaced as needed, but at least every 4 months. (You can order the replacement filter set for up to one year of water treatment in our shop.) In addition, for your own safety, quality samples of the filtered water should be taken and tested at regular intervals.
