Infiltrator Design - Computer Program
(OP)
I'm looking for a good computer program to design storm water infiltration systems. All the SWM programs we have are great at basins, but do not work with infiltration. I've seen some information from pipe/chamber manufacturers, but they don't allow for the manual input of infiltration rates. While assuming zero infiltration might be safest in designing volume required, many municipalities I work with require infiltration rates be accounted for.

Convert the perc rate to feet per second, then multiply by the surface area at the bottom of the infiltration volume.
Set it as a constant outflow rate to be conservative, the rate will actually increase with headwater elevation.
I've never had that method turned down under review, and I've never rejected it on plans I've reviewed, even under Phase II protocols.

Uses Rational Method and average cross section of pond.
An underground infiltration system would have about 45% voids, so would have to reduce average X-section accordingly.
