Partially infiltrating bioretention with underdrain.
Partially infiltrating bioretention with anaerobic/aerobic storage zone.

Overview[edit]

Over soils with slow infiltration rates, it is advantageous to drain a portion of the stored water prior to any upcoming storm. This popular design choice can optimize annual water balance, mitigate peak flow rates and by ensuring water flow through, can reduce the accumulation of sodium and chlorine ions from winter salting.

Materials[edit]

Research[edit]

Bioretention: Partial infiltration volume

Back to Bioretention

A shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation.

The portion of water precipitated onto a catchment area, which then flows as surface discharge from the catchment area past a specified point.

Water from rain, snow melt, or irrigation that flows over the land surface.

A shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation.

A perforated pipe used to assist the draining of soils.

The accounting of inflow and outflow of water in a system according to the components of the hydrologic cycle.
