We know about the water in the toilet trick and we usually fill our tub with water before a storm. We also have a stream that runs through our property. Just concerned about our pump tank backing up because it won't be able to empty without power. We will contact the company that pumps our septic and ask what the capacity is when we don't have electricity.

Typically these systems are designed to have one days worth of capacity remaining even after the high level alarm sounds. This is the alarm that warns the homeowner that the pump isn't operating. You could probably flush toilets as you normally do for 2-3 days without a worry during an outage, even longer if you are skipping showers due to a lack of hot water.
