Storm water is often discharged at our foreshores. Flap Gates can be utilised to stop the flow of tidal water from entering urban storm water systems.
Flap gates are backflow prevention devices. Gravity and head pressure are used to achieve automatic one-way flood, tidal or storm water control.
Pictured is a foreshore location where 15 storm water outlets discharge into the sea.
The AWMA Flap Gates prevent sea water entering the storm water drainage system during high tides. The number and configuration of the gates is due to the limited surface level height and pipe invert depth at the discharge point.
