Manufacturers of perforated pipe are often able to provide the open area (m²) per meter length.

$Q_{max,p}=B\times C_{d}\times A_{o}{\sqrt {2\cdot g\cdot \sum d+}}$

Where:

K_m is the hydraulic conductivity of the filter media (mm/hr),
A_p is the area of the practice (m²),
d_p is the depth of ponding (mm),
d_m is the depth of the filter media (mm), and
Σ d+ is the total depth of bioretention components over the perforated pipe (mm) (e.g. ponding/mulch/filter media/choker layer),
