Wootton Community & Sports Centre and the surrounding housing estate had been experiencing surface water issues following periods of heavy rainfall for a number of years. In particular, visitors to the centre and local residents found integral pavements and roads blocked by floodwater, causing great inconvenience.
The challenge was to resolve the flooding issues affecting the community centre and affecting nearby residential areas with an adoptable and maintainable solution. Anglian Water (Thorpe Wood, Peterborough) identified the need for a system that would create storage at source for excess run-off. It also needed to be easily adopted and maintained, and the completed system needed to be strong enough to cope with heavy loading forces, both during and post-construction.
ACO StormBrixx HD geocellular stormwater management system was selected with three dedicated man access chambers for easy inspection and maintenance. In total, 428m3 of the StormBrixx system was installed at the bottom of one of the Community Centre’s playing fields.
In addition, contractors Barhale PLC received a ‘Toolbox Talk’ training session on the StormBrixx HD system from ACO.
ACO’s StormBrixx HD is a patented plastic geocellular stormwater management system with a high void ratio of 95% thanks to its unique pillar configuration. This minimises the excavation required to achieve a specified storage capacity, reduces the aggregate needed for backfilling, and improves the flow characteristics of run-off through the installed tank.
In addition, the system’s unique brick-bonding and cross-bonding feature provides a strong, long-term installation and helps to improve the construction speed of the tank.
Anglian Water’s Design Engineer, Alec Newson, said: "The use of ACO’s StormBrixx HD system as a design solution, together with ACO’s technical assistance and on-site service, gave us a scheme which could be easily and quickly installed. It also provided us with the ability to inspect and maintain the tank to ensure its continued success in alleviating flooding in the vicinity of the Community Centre and surrounding residential areas.”
