Looking for a leak

I have spent the last week looking for a waterleak that is flooding the basement of a house. This is a leak I picked up with the listening gear and is in anothet St. It has not come to the surface andIroaring its head off,I am not sure if it is coincidence or related, once we renew the service line time will tell, if the water stops in the basement we are hero if not we are zero.
