Flood Barrier In Action

https://flowdefence.com.au Passive Self Activating Flood Barrier New and retrofit installations Activated by flood water not electricity Watch the principles of operation video:    • Flood Barrier   Why do roads flood? Roads are not only used by vehicles, they are also overland flow paths for flood water In minor storm events drains convey stormwater, in major storm events roads convey stormwater Engineering guidelines aim to control the depth of stormwater on roads to about 250mm Flood water depths on roads can increase during intense storm events or in low lying areas that are impacted by tidal effects, storm surge and overland flow The problem? Properties along the roadway and access ramps to basements are at risk of flooding. The solution? The Flow Defence passive self activating flood barrier intercepts flood water in an underground chamber. In minor storm events the buoyant barrier will not activate A submersible pump keeps the chamber drained to ensure that the barrier will only activate when necessary Hydrostatic Fluid Containment System (HFCS) Intellectual Property: WO/2015/120516, AU2015218181, US14902550 More videos at    / flowdefence   https://www.flowdefence.com.au [email protected]
