SUDSPAVE 40 POROUS PAVING INSTALLED FOR ATTENUATION POND AT WAVERLEY GATE DEVELOPMENT
The Waverley project in Rotherham is Yorkshire ’ s largest ever brownfield mixed-use plan , transforming 740 acres of the former Orgreave coal mining site into a sustainable development that includes up to 3,890 homes , shops , restaurants , a school and leisure and community facilities , including parks and 310-acres of green open space .
Project developer Harworth appointed contractor CR Reynolds to carry out drainage and earthworks for the Waverley Gate area of the scheme , including a striking new attenuation pond . Attenuation ponds are a common feature on residential developments and the design forms part of the overall SuDS plan for managing storm water run-off across this area of the site and reducing downstream flooding . The pond also provides attractive amenity space for the new housing estate ’ s residents . In order to provide a sustainable and
functional vehicle access route for servicing of the pond , ABG ’ s Sudspave 40 porous paving was specified .
The Sudspave 40 permeable paving has a grassed surface and also provides a safe , green corridor away from the road for pedestrians and cyclists , whilst enabling surface water to infiltrate into the ground . The design proposed by ABG includes Abgrid Geogrid and Terrex NW geotextile which combine to reduce the required DoT Type 3 sub-base thickness , whilst also providing layer separation and bio-filtration of surface water . The pond also utilises ABG ’ s Claymat clay liner , installed to retain water within the basin . The incorporation of ABG ’ s permeable paving design provided an attractive , serviceable access route and shallower construction profile , resulting in reductions in site excavation , off-site tipping , stone deliveries and associated costs .
