We had a house built three years ago. Never had a problem with water
in the basement...until today. Lots of water down there. We did get a
massive 3" of rain in only a few hours, and the power went out for a
bit so the sump pump couldn't work. This has happened before and there
wasn't any problem. Also none of my neighbors had any flooding
problems and their power was out as well.

Recently builders have dug up the land right beside us as a new
development is going in. Sewers are getting installed. This is the
first big rain since they dug everything up. I'm worried they may have
broken a pipe or done something to cause water to back up into my
basement.

I didn't see any water around the outside of the house. I don't really
know how a sump pump works or how the water gets in there. But I need
to figure this out. I'd appreciate any ideas or input on this. thank
you.
