Permeable Surfaces

The use of permeable surfaces as part of the SUDS treatment train is becoming an increasingly popular and architecturally-attractive means of enabling source control of surface water along areas of hard-standing that would otherwise offer increased impermeable surfaces.

Infiltration Basins, Swales, Trenches and Soakaways

Infiltration basins are man-made depressions, engineered to hold back surface water and let it infiltrate into the soil, thus reducing the volume of run-off needing to be conveyed to end-of-pipe systems. Basins can be landscaped to create structures that appear natural and offer an amenity value for the local community.
