There is a french drain.
The issue is pumps are running every 30 seconds since all the water if funneled to the lower sumps.
The battery back up is the most cost effective and I'll probably go that route. I hope to be out of here in the next two years. The house in SC is high and dry with no basement. Yeah!
The good news is I have great neighbors and the local cooperative has alert capability for notifying power outages via a smart phone so I need about ten hours depending if my wife and I are on a trip...thee neighbors are great but I'm not calling them at zero dark thirty.
The search continues!
