These were the first words I said to my contractor after listening to the message he left me upon installing a sump in the basement. The phrase to which they reply is "You have a river under your house, girl." He was only somewhat exaggerating. Its not undermining the foundations or anything, but there is a body of flowing ground water several feet under the floor of my basement. It appears that when the house was built, it was built on a natural spring . .. which combined with the run off from the road in front of the house, the slope of the land, and the creek in the backyard means that I have an underground stream. Which would be kinda cool, IF it wasn't under my house. I suppose it could come in handy during the zombie apocalypse . . . we can dig a well in the basement. He's pretty confident that we can redirect the water to do no harm (and its not currently harming the house, it just backs up in heavy rain and gives me water in the basement, which the sump should fix. The people who built the place after WWII (namely, the military) must have known, because there also big pipes under the house to direct the water (that was part of what he found while digging out the sump). Ah, the joys of home ownership.
