As part of the rennovation, Charcon developed a bespoke desgin to meet the customer's requirements through utilising a number of SUDs system to meet the various issues
The Cathedral Close project is a £5m scheme to restore the area as an important public space and setting for the cathedral after more than a century of heavy use and natural decay. Part of this has involved improvements to the surface water drainage to meet modern drainage standards using sustainable drainage solutions.
The scheme involved the installation of two attenuation tanks in the vehicular entrance to the cathedral grounds and two infiltration tanks within St John’s Quad.
Restrictions to the discharge to the sewer system meant that a shallow storage solution for surface rainwater was necessary from the roadway within the cathedral grounds. Charcon Permavoid Heavy Duty was selected to provide the required storage volume in a confined area, minimizing the excavation depth required. This was particularly important in the infiltration area where many many graves were found requiring the archaeological removal of these before the scheme could continue.
As one of the UK’s leading SUDs providers with an unparalleled range of integrated SUDs solutions, Charcon is able to deliver a comprehensive cradle to grave total service to its clients, which ensures that a total solution is offered right through for bespoke design, to product specification, to effective the management of all aspects of installation.
