Bioretention Enhanced Design without Underdrain. Bioretention actually bio-detention areas also referred to as bioretention filters bio swales infiltration basins or rain gardens are structural stormwater controls that capture and temporarily store a pre-determined water quality volume WQv using soils and vegetation in shallow basins or landscaped areas to remove pollutants from stormwater runoff. These systems are discrete landscape areas that use specific soils and plant materials to manage stormwater effects. Bioretention filters are equipped with a connection to a local storm sewer system such that water enters the storm sewer after it has filtered through the bioretention cell.
They achieve this by filtering the stormwater through a densely vegetated and biologically active sand and loam filter.
