Agreed - that would be the single point of failure in such a system.The biggest issue I see is a pump failure in the control bucket.
Assuming you have the whole system running off a single circuit, if you have your "delivery" pump on a timer that will never supply more than half the sump's total volume during any fertigation cycle, then even in the event of a power failure, your system would never overflow.
The alternative would be to go "overkill" on the sump's volume (say double?). That way, you'll have 2 chances to catch an overflow situation before it gets out of hand.
Here's me with no experience in such systems thinking-through possible "outlier" situations/contingencies...... Anyone would think I know what the fuck I'm talking about!
