Detention is the Sustainable urban Drainage Systems (SuDS) technique of holding that water at the site, so it can be either re-used or discharged to the drains at a controlled flowrate that the existing infrastructure is able to handle.
Polypipe's innovative detention stormwater management systems include the Polystorm and Permavoid ranges. Both use modular cells protected by non-permeable geotextiles, with plastic pipe components, providing superior performance to traditional legacy materials.
