Here in NW Iowa we get some BIG storms, the town my office is located in is STORM Lake, with those rains come flooded basements, overwhelmed sanitary sewers and in essence a big mess. I've been reading on a Water Powered Backup Sump Pump that uses water to pump water, it doesn't need electricity or battery backup. http://www.familyhandyman.com/basement/using-a-water-powered-backup-sump-pump
Anyopne out there have any experience with these, if they work they could be a tremendous help in my area. I've included a link to the best article I could find on the pumps. Thank you everyone!
