Context

In 2014, Norfolk County Council (NCC), in partnership with Great Yarmouth Borough Council (GYBC), proposed the creation of a new bypass road on the outskirts of the town and called upon ACO Water Management to provide the accompanying sustainable highway drainage. The road would address the chronic congestion at the gateway to Great Yarmouth and would facilitate a much-needed extension to the existing development at Bradwell, leading to the potential creation of 850 new homes, as well as new opportunities for local businesses.

Challenge

The project challenge was to provide a sustainable highways drainage solution. Project engineers, Mott MacDonald, proposed a design which would see the highway surface water drain into parallel swales on either side of the carriageway and ACO KerbDrain and ACO SuDS Swale Inlets were chosen as the ideal solution.

Solution

ACO KerbDrain units, a combined kerb and drainage system, were used to collect surface water along the A12. The units were then connected to a series of ACO SuDS Swale Inlets, which have been designed to link proprietary conveyance drainage systems, such as KerbDrain, to vegetated infiltration features. The ACO SuDS Swale Inlets had outfalls at 10m centres along the A12, to discharge the surface water via infiltration into the subsoils of the Swales.
