Both my current home and the home I am moving to have open pipes coming out of the ground near the downspouts from the gutters. I assume these are some type of drywell. In both cases the former owners have decided not to use them and let the rainwater go right on the lawn. Do drywells eventually fail? Any idea what was common practice when the installed drywells back around 1900 in the Northeast? I'm curious where that pipe ends up.
