I could use a sump pump

I live in an area which gets a great deal of rain and the water table is very high.  For years, I lived with a wet basement. The space was virtually unusable, always smelled musty, and I worried about mold.  However, with five kids, we needed to somehow expand our living space. The easiest and most inexpensive option was to remodel the basement.  The full basement provided enough space to put in two bathrooms and a full bathroom. We also hoped to move the laundry room down there and free up an additional room upstairs.  The problem was the excessive moisture. At certain times of year, there was even standing water in the basement. I wasn’t quite sure who to call for advice, but I finally consulted with a local plumber.  He recommended that we install a sump pump in the basement. The sump pump is submerged into a pit drilled into the floor, and activates automatically whenever the groundwater level rises. It effectively pumps the water out of the basement, preventing flooding.  We then added a dehumidifier to combat musty smells, moisture, and any potential mildew, bacteria or mold growth. We were delighted when our basement was suddenly dry. We went ahead and remodeled, putting down carpets, insulating the walls, and moving in beds, dressers, and my washer and dryer.  Everything was perfect for about six months. Then we faced a power outage during a spring storm. The sump pump doesn’t operate without electricity and the basement flooded. There was six inches of standing water, and it caused a great deal of damage. I then learned about battery backup sump pumps.   I wish the plumber would have mentioned this option before we dealt with that huge disaster.
