Strengthening the flood defences in Birmingham

When freak storms and flash floods struck Birmingham in the summer, the city's council needed to take swift action. Gravitas International sprung into action and distributed its HydroSacks to hundreds of stricken residents.

Birmingham City Council (BCC) and flood protection product manufacturer Gravitas International have worked together to help strengthen the city’s flood defences.

Despite budget cuts and a lack of investment in flood protection, the council had to react quickly and efficiently to protect the community during the summer Birmingham was hit by a day of freak storms and flash flooding, putting hundreds of homes and businesses at risk.

When the storms hit the city, Gravitas International was quick to respond, supplying more than £3,000 worth of products to help local people.

Birmingham City Council asked Gravitas to help the flood stricken area of Witton. Gravitas’ flood response team distributed about 500 units of its HydroSack flood defence product to worried residents and business owners.

The HydroSack was launched in January 2012 to provide improved performance, cost efficiency, storage and ease of use in emergency flood protection.

Until now, the only other option for flood defence has been to use heavy sandbags, which are not only ineffective, but labour intensive and a potential health hazard, claims Gravitas.

The HydroSack, and its sister product the HydroSnake, are manufactured from a non-woven fabric that covers pads of super absorbent polymer (SAP).

Weighing just short of a kilo, the bags are extremely lightweight, making them easy to deploy into position. Upon contact with water, the SAP crystallises, dramatically increasing in size and weight, to form an effective barrier against flood water.

David Sallon, managing director of Gravitas International and creator of the HydroSack, says: “We developed the HydroSack after recognising that current flood defence products were severely lacking in usability. Sandbags have been used for hundreds of years, despite being highly deficient.

“They are difficult to store, leak water and store toxins from flood water. Our aim was to create something that is much more time and cost effective.”

Due to its flexible supply chain, Gravitas was able to react rapidly and was in position, distributing HydroSacks, within three hours of the flood alerts. It, reportedly, had the quickest response time of any party involved in the flood defence strategy on the day.

Gravitas also worked with local flood action groups to pinpoints areas that had been acutely affected by the flooding. This ensured that the product was delivered quickly and efficiently to those who needed it the most.

Clive Wright, drainage and flood risk manager at Birmingham City Council, says: “The HydroSacks were distributed to residents in Witton to protect them from rising river levels. Units that were left over have now been distributed amongst three main flood action groups, which are storing them economically and will deploy them when necessary.

“The addition of the HydroSacks to our flood plans has given even greater confidence to the communities we are protecting. They can be distributed at the earliest opportunity, whilst we work hard to deploy further resources to flood areas.”

Ray Nicholls, chairman of Witton Flood Action Group, comments: “We were extremely grateful to have HydroSacks to give out to residents, so they could be as prepared as possible. It’s a great asset to the community, because local people can easily store the HydroSacks and be ready to protect themselves when the flash floods come.

“The problem with sandbags is that they need to be pre-filled and have a limited shelf life. HydroSacks can be easily stored for very long periods of time, meaning residents can be self-sufficient in flood defence and prepare in advance.”

Since the flash floods struck, Birmingham City Council has further strengthened the action plan with flood action groups, with a focus on very open lines of communication – meaning improved future response times to impending flood problems.

This flood risk plan has been combined with more effective flood defence products, such as the HydroSack, which complement the strategy. It will undoubtedly lead to time and cost savings in the future, as well as ensuring the utmost protection possible for communities.
