Storage basin volume -  ALL FLOW into the junction is directed into storage until the basin fills.  Once it is full, flow is initially directed to any in- system storage specified for the junction, and then overflows to the overflow junction.  When the storage basin receives no inflow for the number of hours specified as "storage basin detention time", it begins to release flow from storage to its principal and/or secondary downstream structure(s) at the treatment rate specified for the junction.  The basin thus functions as a holding tank.  It should normally be the overflow structure for a regulator, and should receive no dry weather flow (otherwise it will never empty).  Its overflow would typically be to an outfall.  The treatment rate is the rate at which the basin is emptied to the WWTP.
