*The overflow must be situated at the far end of the facility to prevent any localised ponding to cause bypassing of the infiltration facility.  

*The overflow must be situated at the far end of the facility to prevent any localised ponding to cause bypassing of the infiltration facility.  

*Offline facilities use flow splitters or bypass channels that only allow the required water quality storage volume to enter the facility.  

*Offline facilities use flow splitters or bypass channels that only allow the design storm runoff storage volume to enter the facility.  

:Higher flows are diverted and do not enter the infiltration practice. A pipe can by used for this, but a [[weir]] or [[curb cuts|curb cut]] minimizes clogging and reduces the maintenance frequency.

:Higher flows are conveyed to a downstream storm sewer or other BMP.
