CG501 “Design of Highway Drainage Systems” was published on the Highways England DRMB website on 31 October and replaces HD33.

For road users, the changes mean that better designs, completed more efficiently, should ultimately improve the performance of the systems draining our strategic road network.

Users of the new DMRB drainage documents will find them easier to navigate, significantly more succinct, and consistent in differentiating requirements from recommendations.

In an article published by Highways magazine, Ramboll’s Steve Cox describes how, under commission by Highways England’s Santi Santhalingam (owner of the DMRB drainage documents), is leading a consortium from WSP, Mott MacDonald, AECOM, Jacobs and Ramboll.

Some of the revised documents have already been published on Highways England’s Standards for Highways website, with the remainder due for publication before the end of 2019.
