Rainwater flooding

Flooding due to heavy rainfall or high surface water levels.

Long dry periods with high temperatures and short heavy rainfall alternate each other more often. In cities, with increasing paved surface, this leads to nuisance of flooding and water shortage. This imbalance has negative consequences for the environment, economy and society. Moreover, the need for clean, good quality water, in adequate amounts increases.



The Rainwinner can be used to manage rainwater in the urban area. It consists of hollow modules with a 110 liter rainwater storage capacity. The modules are stackable and easily connectable to each other. They can be used as, for example, a fence, border edge, bench or sound wall. The system ensures a balance in the water availability by temporarily storing excess rainwater which can be used in periods of water shortage.



  • If desired, the modules can be decorated.
  • Can be incorporated into stone grains to allow use in public areas.
  • Multifunctional garden element.
  • Adjustable to the desired capacity.
  • An infiltration unit will allow the water to infiltrate into the soil.
