RainWaterWall

What it is

The RainWaterWall (RWW) is a long, thin and high tank, located at ground level. Rainwater routed from nearby roofs is stored in the RWW-tank. The RWW is tailor made, modular based and is placed next to blind walls of premises, sheds, schools, and building blocks. The tank can also be used as a partition between plots. You can choose the RWW to be delivered in green- or in the galvanized steel color.

RWW to reduce impact climate change 

Due to climate change we are more often confronted with periods of drought ánd periods of abundant rainfall. Both situations can lead to problems for which the RWW offers a solution: 

Dry periods: buffer rainwater

Periods of drought can result in shortages of (rain) water and the ban on watering gardens, (car) washing, flushing toilets, etc. By connecting the RWW to existing downspouts routing water from the nearby roof(s), large amounts of rainwater can be collected, buffered prior to dry periods, and put to good use once the drought sets in.

Wet periods: prevent flooding

We offer to link the RWW to an online weather system to help preventing the sewer from flooding during wet periods. The online system signals when heavy rainfall is likely to occur in the very near future. At that point a valve is automatically opened to discharge water out of the RWW into the sewer system which is by then not yet overloaded.  Once the expected heavy shower breaks loose, the fresh rainwater can be stored in the RWW which has been emptied. Applying this strategy, the RWW can support you to prevent flooding and minimize economic damage as a result.  

Some technical details

One RWW can contain from 5 to 25 cubic meters of rainwater. The tank is delivered with a faucet connection upon need. The stored water can thus be easily transported with a hose and/or pump to nearby locations.

 Examples of applications of RainWaterWall

• supply rainwater for toilet and washing machines;

• collecting water for vertical walls;

• collecting water for (indoor) gardens of companies. 

Use Dutch decoupling- and climate subsidies

The Dutch Government, municipalities and Water Boards increasingly offer decoupling subsidies, climate, and incentive subsidies to help improving the sustainability of your property. As a result, the net cost of the RWW-system can be lowered substantially. 

Lower water bill and reduced sewer charges

Rainwater is free, so your water bill will thus be immediately reduced. Further, since sewer charges are often linked to your water consumption, this will result in a lower sewage charge as well.
