Polypipe was selected to provide a shallow attenuation solution incorporating treatment as part of works to create a new head office for one of the world’s leading online gambling companies.
Permachannel acts to capture silt and oils, whilst the Permavoid Biomat’s tri-laminate low density composite mat traps hydrocarbons.
The shallowers system limited the need for strenuous excavation on-site, saving vital time and cost while reducing potential health and safety risks.
Consisting of 21 different runs of Permachannel and Permavoid Biomat, which linked to 21 Polystorm-R geocellular attenuation tanks, the design is capable of storing more than 400m3 of stormwater beneath the development’s car park, at a depth of just 1m.
Permavoid Biomat can encourage the reproduction of microbes to breakdown oil deposits
The run-off stormwater is initially collected within the Permachannel, which was installed at pavement level to provide initial source control, as well as the first stage of water treatment by capturing silt and oil. Once entering the Permachannel, the water then passes through the system into Permavoid Biomat cells containing a tri-laminate low density composite biomat.
The future we want to build gives everyone the opportunity to build a better future for themselves.
