Many of the dimensions in a bioretention system are relatively constrained by the performance requirements of the individual component. There is greatest flexibility in the ponding depth and the depth of the storage reservoir beneath the optional underdrain pipe. The order of operations in calculating these dimensions depends on whether an underdrain is desired.

Component Void ratio Recommended depth (with underdrain pipe) Recommended depth (no underdrain pipe)
Ponding depth 1 300 mm See below
Mulch
  • 0.7 for wood based
  • 0.4 for aggregates
75 ± 25 mm
Biofiler media 0.3 typical
  • 300 mm to support turf grass and accept only roof runoff
  • 600 mm to support flowering perennials and decorative grasses
  • 1000 mm to support trees
Choker course 0.4 typical 100 mm
Embedding reservoir 0.4 Is equal to underdrain pipe diameter Not applicable
Storage reservoir 0.4 See below See below
