Swales gain valuable urban functions with Rockflow
The integration of swales in residential areas involves significant urban development challenges. The space available for the collection of excess rainwater is often restricted. As a result a swale must be relatively deep, which means that the sides are often steep. This can create a hazardous situation and makes maintenance difficult, leading to regular problems when the swale becomes overgrown with weeds or blocked with litter. Furthermore, the capacity gradually decreases due to a layer of silt accumulating over time, hindering the infiltration of the water into the soil.
Additionally, traditional swales can only be used for the purpose for which they are intended: the collection of rainwater during heavy showers. The surface is then no longer usable for any other purpose.
