BTW Mrs.E, the valve on the potential e-drain is in case you need to close off for maintenance.
You should decide if you want to combine into sump or leave separate. If there are only two standpipes, I would keep separated and do as Jaws suggested - that's what Id do.
Make sure you use a strainer on siphon overflow to reduce the risk of clogs.
