Summary of Bioretention Variants for Permeability of Native Soils and Potential Land use Pollutant Loading
(Link to this table)
Bioretention Type | Variant | Underlying Soil Performance Criteria |
---|---|---|
Bioinfiltration (Infiltration/Recharge Facility) | No underdrain | Higher recharge potential (facility drain time without underdrain is 48 hours or less) |
Biofiltration with underdrain at the bottom (Filtration/Partial Recharge Facility) | Underdrain | Lower recharge potential (facility drain time without underdrain is > 48 hours) |
biofiltration with internal water storage | underdrain | Lower recharge potential (facility drain time without underdrain is >48 hours) |
Biofiltration with elevated underdrain (Infiltration/Filtration/Recharge Facility) | Elevated underdrain | Higher nutrient loadings and/or quantity control |
Biofiltration with liner (Filtration Only Facility) | Underdrain with liner | Hot Spot Treatment |
