Creation of a landscaped sales village with surface water run-off used sustainably to create a series of ponds and wetlands.
1. Stand-alone system with no connection to sewer or watercourse.
2. Provide sufficient attenuation to prevent standing water in customer access areas.
3. Visually harmonise with rural landscape setting.
WDW worked with ACO’s Design Services Team to develop a SUDS to integrate with proposed wetlands and complement the setting.
Analysis of the site showed that ACO MultiDrain channel runs linked to a network of ponds, wetlands and swales could sustainably manage the run-off from new hardstandings.
Eight runs of ACO MultiDrain M100D are installed at strategic points. All are interlinked, carrying run-off to the network of ditches, ponds, wetlands and soakaways that regulate the rate of return to the surrounding groundwater. Main display area runs are curved to match the contours of the landscape and fitted with cast iron gratings.
ACO MultiDrain MD's design gives it the highest strength to weight ratio of any system in its class. Capable of withstanding loads from Class A through to Load Class D, the lightweight MultiDrain MD not only increases the number of applications that can be covered by a single system it also includes new features that improve on-site handling, finish quality and installed performance – it is the first drain in this category to be available with a sloping invert.
With high strength UltraSTEEL™ edge rails and Drainlock™ bar-less grating locking system, ACO MultiDrain has a unique internal ‘V’ profile that increases the flow speed of drained water – promoting self-cleaning and extending the intervals required between routine maintenance.
“ACO’s team was able to develop a complete dynamic model which mapped the hydraulic performance of the proposed system,” says Harry Wilson, Partner at WDW Architects. “The analysis proved that the retention and infiltration characteristics of the ponds and wetlands could be coupled with the attenuating capacity of the drainage channel runs to create a fully self-contained and self-balancing sustainable drainage system that would not need to connect to the main sewer network.”
“The addition of water features at the Salop Leisure site will not only enhance the ‘holiday’ feel of the site, they will attract bird and aquatic life and help to sustain bio-diversity in the area,” says Peter Bembridge of ACO Water Management. “ACO MultiDrain MD itself is environmentally sustainable as it is manufactured from Vienite – a breakthrough recycled and fully recyclable material.”
