Currently I am working on getting the drawdown for my bioretention basins below three days. The controlling factor seems to be the infiltration rate of whatever soil mixture I use. Now realistically I know the best soil type I may ever get is 5 to 6 inches, but this won't allow me to drain the entire bioretention bmp volume within the 3 days required. Does anyone know if infiltration rates of 12 - 15 inches per hour is realistic? Do these infiltration rates possibly account for evaporation and evapotranspiration from plants inside the bioretention basins?
Any help would be appreciated.
