You can install a water or battery backup sump pump. Both are reliable but the battery will run down and the water is wasteful so if you expect a lot of 24 hour or longer power outages then you ought to buy a generator. Ive installed a lot of emergency back up sump pumps and they work great. PlumbingWarehouse has good prices and good service on the net.Ive included a picture of the water pressure type of backup unit.
