Hybrid Polystorm Solution for RAF Development

Incorporating both the Polystorm and Polystorm Lite sustainable drainage solutions, the project at RAF Northolt, Cambridgeshire was part of the £600 million MoD Single Living Accommodation Modernisation Scheme (SLAM) designed to deliver living accommodation for MoD personnel.

The original project specification was changed from a concrete box culvert due to issues with rising material costs and concerns over the performance of the product in times of high-flow water run-off. However, a solution was needed that was capable of storing the required water capacity whilst accommodating difficult site constraints. The modular construction of Polystorm and Polystorm Lite allowed Polystorm cells to be connected together to cope with the uneven burial depths on-site and a bespoke designed manifold system was also incorporated to improve hydraulic performance.
