DECELERATES THE DISCHARGE AND ACTIVATES UNUSED STORAGE VOLUME IN SEWER NETWORKS

The Problem

Measures to protect waters are necessary but often expensive. Legislation demands storage basins for the protection of receiving waters such as streams, rivers and lakes. Because of the huge investment costs involved, municipalities are seldom able to build such structures. Action is also called for when the canals in an urban area are overburdened due to new development areas. The removal of sealed surfaces is often not sufficient so that either buffer basins have to be built or whole canal sections replaced to secure the older parts of the urban area.

The Solution

A canal system usually has large unused storage capacities since it was built for maximum loads. The HydroStyx discharge brake allows this hidden capital to be utilized. When there is stormwater, the HydroStyx discharge brake allows the canal volume to be used as retention volume.
