Groundwater recharge

Infiltration basins
SuDS can increase infiltration to groundwater. This can help maintain natural hydrology, increase availability of water for abstraction or reduce treatment costs, as the benefits pathway diagram below shows, this impact assumes that the designer understands whether infiltration is possible and allowed. It is likely to be relevant only where groundwater is over-abstracted, where the groundwater body is in an area of moderate or serious water stress or during very dry/drought periods.
