Incorporating Polystorm and Polystorm Lite sustainable drainage products, the project at RAF Northolt was part of the £600 million MOD Single Living Accommodation Modernisation (SLAM) scheme.
The original project specification had been changed from a concrete box culvert because of rising material costs and concerns over performance in times of high-flow water run-off.
A system was needed that would storing the required water capacity whilst accommodating site constraints. The modular construction of Polystorm and Polystorm Lite allows the cells to be connected together to form almost any shape and storage capacity.
Approximately 3000 Polystorm and Polystorm Lite cells were installed on-site to provide an attenuation system that could to cope with surface water run-off from both hard standing and roof areas.
