jim:

I'm in Greenville, N.C.
I accidently ratted out the practice.
I inspected a crawl space with a sump pump and casually called one of my better friends who manages a division of Greenville Utilities. He asked up the line and I had an idea that it was against the policy of the utility co to dump anything into the sewer other than house waste. He confirmed that as well as that condensate was also improper and, in fact, statutorily illegal.
Why would any condenste pose a foundation issue if it is properly lead away from the house by proper grading?
Around here, we're just a smidge above sea level as it is, but decent grading will disburse that amount of water satisfactorily.
