ACO takes on the drainage Burden

The channel drainage system installed at Burdens’ new depot on the outskirts of Cambridge ensures that the yard’s 10,000m2 of hardstanding is effectively drained even though the site has virtually no fall and the water table lies just below the surface. Designed by ACO Technologies, the system uses a series of high capacity ACO S Range heavy duty channel runs to provide the required hydraulic capacity and to create sufficient internal head to discharge surface water runoff from the site at the rate specified by the Environment Agency.

The key element to the successful solution that ACO’s team has designed is a linked, double run of ACO S300 that receives runoff from a network of smaller S200 and S100 runs across the site. The ACO S300 channel has a depth to invert of 360mm, allowing it to sit within the available depth on the site. The parallel runs of channel, which do not include any additional sumps or pipework, provide sufficient capacity to cope with the design storm rainfall intensity of 55mm/h.
