DRAINAGE & PLUMBING
HIGHWAY DRAINAGE AND SURFACE WATER MANAGEMENT
With the weather once again turning wetter, the simple A to B on our roads can become a log-flume ride. ACO looks at their solutions to the dangerous issue of waterlogged roads and what it will take to keep our highways safe enough in the rain...

ffective management of surface water for all highways and trunk roads is essential for safe use by both vehicles and pedestrians. As a major supplier to highway schemes across the UK for many years, ACO understands these demanding operational challenges and the importance of delivering high-performance surface water management systems.
ACO provides a comprehensive range of highways-specific drainage solutions that support essential road infrastructure in highways, trunk roads, urban roads, footpaths and highways conservation. With design support and Civil 3D BIM files as well as SuDS solutions, ACO assists the infrastructure industry in making, mapping and maintaining the network.
Highways conservation ACO has been involved in highways conservation for many years and has a number of specific solutions to help animals coexist alongside the road network. Seasonal migration in particular, between land habitats and vital spawning grounds, offers dangers

when road networks cross these routes. The ACO guide wall and climate tunnels help guide and protect small animals around and under roads and ACO also has refuges and nest boxes to support environmental considerations as a part of new road projects.
Trunk roads
ACO has a number of high-capacity drainage solutions to ensure road surfaces remain as free from standing water as possible on trunk roads. H Range and RoadDrain are monocast products that have been developed specifically for the highways sector with F 900 load class for dealing with heavy-goods traffic. For highways infrastructure projects where BIM (Building Information Modelling) is used, ACO has produced Civil 3D models of the range to support the most advanced working methods in creating and mapping the network.
Urban Roads
ACO KerbDrain is a combined drainage and kerb product and an ideal solution to support parking infrastructure at Distribution and Warehouse facilities. Polluted water runoff in
parking areas and near refuelling bays can be managed by ACO QuadraCeptor, which is an effective cleaning solution that removes heavy particles, silt, nutrients and dissolved materials, such as heavy metals.
Footpaths
One of the ways pedestrian safety is integrated into drainage for road network footpaths is by HeelguardTM gratings. These are fitted to drainage channels such as ACO Multiline Sealin and MultiDrain MD or MultiDrain PPD, and the 10mm slot widths are a more ‘heel-friendly’ option for footpaths.
Structures
In the Hindhead Tunnel in Surrey, ACO KerbDrain has been installed on each 1.8km twin-bore tunnel carriageway. The fact that it carries the BSI Kitemark gave the design engineers absolute assurance that KerbDrain met the latest Highways Agency requirements. Other solutions include ACO Deckline, where the product’s shallow invert channel drainage system make it ideally suited for use in structural slabs or where excavation depth is limited. BMJ
