ACO Water Management has provided a complete surface water management solution at Network Rails Three Bridges railway maintenance depot near Crawley. By utilising products from its permanent way and rail infrastructure range, ACO was able to meet the projects specification and help overcome challenging on-site logistics.
The new rail depot is part of the Thameslink rolling stock project, which is an initiative to provide additional passenger capacity and remove bottlenecks on the London commuter network. Two ACO StormBrixx tanks, of 1150m3 and 370m3 volume, were integral to the surface water solution. The unique geocellular stormwater management system is designed to stack for shipment, saving space and keeping transport costs to a minimum. With smaller delivery vehicles required to reach the Three Bridges site, this meant deliveries were minimised ACO StormBrixx was supplied using around 75% less deliveries than would have been required for comparative tanks.
A series of drainage channels were also used on site. For the efficient removal of fluids from the service pits in the main train care and wash-down facilities ACO supplied 1500m of ACO MultiDrain MD channel drainage, fitted with sump units and roddable foul air traps to prevent debris from entering the drainage system.
