Bioswales are installed as an alternative to underground storm sewers. The bioswale is engineered so runoff from a 1.25" rain infiltrates into the soil below.  When larger storms occur, bioswales slow the flow of runoff while using above ground vegetation to filter and clean it before it flows into the local stream or waterbody.
