Rubber Duckbill Valve array meets IOM challende head on!

This site in Douglas on the Isle of Man required a robust solution to solve problems of a large culvert exiting into a chamber in the sea wall that is exposed to high seas. We proposed and provided a GuvNu Array assembly of 5 rubber check valves, that is still showing no signs of fatigue since installation in 2000.

Client: Isle of Man Water Authority

Design GuvNu Array of 5No. Rubber Tideflex valves

The Isle of Man is a self-governing British crown dependency located in the Irish Sea almost equally-distant from the four countries of the United Kingdom. As such, its coastline is regularly battered by high seas. As the sea level has risen, Douglas, being a Victorian town, has suffered flooding in recent times.

IOM is probably most well-known for its annual motorcycle road racing event, the TT races, which starts and ends in the capital, Douglas. This, and other events thoughout the year, mean that Douglas hosts a large number of tourists annually. It cannot afford to have its beaches and landmark promenade affected by bathing water quality issues either.

This makes it all the more important that drainage outfalls perform as designed, no matter the weather. And this is where rubber duckbill valves come into their own! When the waves hit the sea wall the valves seal to prevent seawater ingress and are repeatedly compressed, with no fatigue.
