Back to startup overview


The Polderroof is a solution that provides rainwater storage on rooftops in densely populated areas and buffers showers that are getting more extreme. By creating a water basin on the roof surface a badly used surface is turned into a local water storage.  

The Polderroof can store 99% of rainfall of all showers thereby reducing nuisance from rainwater on street level and reducing sewer overflow. This is all made possible by the control units on the Polderroof. These units are equipped with sensors and operate according to a strategy. On a website data can be managed and the strategy can be set. This is how the Polderroof creates water management on rooftops.
