In response to Re: Lowering basement slab - what about main DWV line?
Be aware that the DWV line doesn't neccessarily HAVE to go under the floor of the basement to the point where it leaves the house, you could runn it along a wall then down to hook up with the existing pipe leaving the basement, even add a toilet if you have the fall available. I'd try to avoid digging up the line to the street. : It's a brick house, so raising the house is not cost effective (at least so far). I have done some excavation for other projects and found that the footings go well deep enough for this.

: My big worry is the depth (and effort) of the main in the street. Would the water/sewer authority have this information? If not, is there a way to get it?

: Thanks, Matt

: : And what if the main in the street is not deep enough? I am not sure how much this would cost you, but the other thing you have to consider is if you make that excavation you will be digging lower than the footings and so will either have to stabilize them somehow, or dig far enough away from them so that the soil is not disturbed around or under them. Have you checked into what it would cost to raise the house a foot?
