Permeable paving at the head

A new case study from the trade association Interpave discusses how master-planning, urban design, hard landscape and external surfaces have been integrated with sustainable drainage systems

(SuDS) – featuring concrete block permeable paving – on a major, phased development in Oxfordshire.

Great Western Park is being developed over 9 phases on 160 Ha of essentially green-field land to the immediate west of Didcot. Once complete, it will eventually provide 3,000 new homes and related facilities. The use of concrete block permeable paving is an essential component at the head of an intergrated SuDS management train throughout this major new development.

Concrete block permeable paving is used widely as a source control, providing both rainwater attenuation and pollution removal, particularly in the more urban situations, without demanding any additional land-take. It also drains adjacent impermeable areas, such as conventional concrete block paving.

The case study considers aspects of the master-plan, including street design and its integration with the drainage strategy based on SuDS principles. It then focuses on implementation within the partially completed first phase of the project.
