Almost everywhere, water pressure fails a lot less than electric power

Yes, but a water powered pump is still reliant on an external power
source.

So what?? It's a source that almost never goes down.

That depends entirely on where you are. A lot of areas have 100yr+ old
infrastructure that isn't as reliable as you claim. The main thing is
not that city water is so miraculously reliable, it's the odds of both
the water and power being out at the same time and that usually only
happens under conditions where the sump pump is the least of your
concerns.

Water pressure is *far* more reliable than electric service in most places,
whether you know it or not.

Not in any of the places I've lived or the areas adjacent to them.
