There are new insights into the environmental damage caused by run-off from paved areas, car parks and other features of development and urbanisation. Rainwater falling onto these areas is collected via traditional engineered methods such as kerbside drains, gullies and pipes ensuring all surface run-off water reaches the nearest sewage works or watercourse very quickly, often causing sewers to overflow due to the volume of water. This gives an enormous shock-load of volume and pollution to the receiving water or sewage treatment works.
The best method of stormwater management is to dissipate the flow through infiltration and retention. Constructed wetlands provide the ideal environment in providing these conditions, with the addition of removing impurities through settlement and filtration.
Stormflow reed beds have been utilised by several water companies as the provide additional storage whilst providing treatment.
