An immediate test - Passed

Just four weeks after the White Cart Flood Prevention Scheme had its official inauguration, the new flood defences successfully held back rising water and helped protect hundreds of homes and businesses within Glasgow.

Heavy rain and wind at the end of November 2011 caused flooding across many parts of Scotland. Officials at Glasgow City Council said that all the defences were monitored throughout the flood threat and they worked extremely well during the storm.

It is estimated that nearly £11 million of flood damage would have been inflicted on homes and businesses in the south side of the city without these new defences.

Gordon Matheson, Leader of Glasgow City Council, said: “This was a major test for these new flood defences since its

inauguration and they have passed with flying colours.

Blackhouse flood storage area The World’s largest Hydro-Brakes

The Hydro-Brake® Flow Controls were installed into three dams, they are designed to hold back water in three flood storage areas upstream of Glasgow, which together have the capability to hold back millions of gallons of floodwater generated by extreme rainfall.

Manufacturer Hydro International had to

pioneer new manufacturing and installation techniques to construct the eight-metre long, six metre-high, cone-shaped Hydro-Brake® Flow Controls which were positioned in dams at Blackhouse and Kittoch. A further three Hydro-Brake® Flow Controls were installed in the dam at Kirkland Bridge.

The hydro-brakes have a combined stainless steel weight of more than 60 tonnes and all five are the biggest ever produced.

Since Hydro International developed and pioneered the Hydro-Brake® Flow Control’s unique vortex technology 30 years ago, it has become an industry-standard method of flow attenuation. Most frequently used in much smaller dimensions as part of urban surface water drainage designs, the Hydro- Brake® Flow Control’s internal geometry is designed to enable water to flow through unrestricted for as long as possible. A self- activating vortex is created when the water reaches a pre-determined height, for example in a flood situation, holding back the water, and releasing it at a measured, controlled rate.

investment and commitment by the council to protect homes within the south side of the city. I am sure that these new defence have brought huge comfort to local Glasgow residents and businesses that heavy rains now won’t cause havoc and flooding to their properties.”

During the last days of November, the three reservoirs held a total of 237 million gallons of flood water, the same amount as approximately 350 Olympic- size swimming pools – which is about 43% of the total storage volume.
