Urban stormdrain basin delineation

I am trying to delineate drainage basins that contribute to an urban stormdrain network (hundreds of inlets collect the surface runoff, and convey it thru underground infrastructure).  The ArcHydro / GeoHMS tools are great at delineating surface drainage networks, but I am at a loss for how best to proceed.  I will try delineating basins without filling sinks (many of the stormdrain inlets are in local low points) and with the stream definition set quite small, then go thru visually combining sub-basins, but this will be more laborious than desired.

 

Thanks,

Andy
