Managing the flow

Our traditional sewers and drainage systems can not cope with the large volumes of surface water flowing in developed areas. Development for housing, roads, shops etc has created more hard, impermable surfaces, giving water less opportunities to soak away, or be evaporated. As a result, when a storm event hits, the flow has nowhere to go other than into the drains. Once these reach capacity, surface water floods form, often creating traffic chaos the potential to damage property and pollute water supplies. In order to provide more soft, permeable areas for water to soakway and be filtered from pollutants, we need to change the way we plan our cities, town and villages.
