also look at water powered sump pumps.

A good idea. No battery powered pump is going to last long when it
is really needed, unless it has too small a capacity to keep up or has
a few grand worth of batteries.

It is very rare for the water supply to your home to go out, even
when the power is off. Yes, you can pump water with water.
