Before society added so many roads, car parks and buildings, roughly 80 percent of the rain that fell in a natural catchment would typically soak into the ground where it would be filtered and cleansed before gradually recharging our aquifers. With increasing urbanization, globally, communities are facing a rising tide of flooding incidents. Today, in most urbanized catchments, more than 80 percent of the rain ends up as stormwater runoff with the resulting increased runoff flow rates and volumes causing flooding problems.

Using a Hydro-Brake Flow Control runoff can be controlled at source to prevent downstream flooding, be it in small applications like individual devlopments, to large scale projects like managing the flow of a river.
