Flooding has become a seasonal menace
Flooding is a common issue faced by most of the low-lying areas major cities in Asia. Often this is compounded by population growth, high annual rainfall and limited space. Soil surface subsidence accompanied by industrialisation and urbanisation further aggravates the situation.
With rapid urbanisation, this flooding is unavoidable , but it can be controlled to minimise losses and damages.
Grundfos has a new innovative solution that protects areas from flooding without the traditional space requirements for a pumping station. Combining floodgates and axial flow pumps gives a ‘Pump Gate’ solution on an existing waterway, relieving flood pressure with very easy operation and maintenance.
How Pump Gate works
A Pump Gate consists of a floodgate on an existing waterway equipped with pumps. This removes the need for a separate floodgate, pumping station and reservoir, all of which take up space. Building the submersible pump directly into the floodgate means that the function of a floodgate can be combined with the function of a pumping station and reservoir.
The floodgate and screen can be opened to discharge the retained water by gravity flow. And if the water outside the floodgate gets higher, the Pump Gate can be closed to block back flow. If the retained water reaches a certain level, the pump starts operating to forcibly discharge the retained water.
