Thanks everyone for the replies. We have done some more checking and
verified the two unknown pipes are NOT wastewater from other
properties. We have also verified the downspouts go to the street
gutter now (but probably did feed into these two pipes originally). My
question now is, do you think it's likely that a perimieter drain
system (under the foundation) may still feed into these pipes? A
contractor we asked told us this is quite possible in a home 50 years
We cannot just connect these pipes back up to the side sewer, as the
City will not allow it, knowing the pipes are not wastewater. Even
though the downspouts no longer feed into these pipes, if they are
collecting stormwater then the discharge ends have to be connected to
something, otherwise water will collect around the foundation.
Suppose they are perimeter drains. And suppose they did go to the sewer.
In the process of installing new line, you'll likely need to have the line
surrounded with stone. Well, if I were doing it, I'd probably go ahead with
the installation project, and do all the things that needed to be done. As
well as putting a bag and some dirt over the ends
so they wouldn't even be apparent when the pipe was being inspected and
smoketested, if it is.
Then, before things started being filled back up with gravel and dirt, I'd
uncover them and let their drainage be by way of the gravel surrounding the
I suspect that they could well be perimeter drain, and if it is, you've got
a path already to the street. Matter of fact, there are some folks that have
connected a 2" line to their perimeter drain pipes and ran it further below
grade to the street as they were putting in their gravel after inspection.
Would certainly never show if they ran a camera up your line. And after all,
you wouldn't be connecting to the sewer.
See how a smoke test gets done. I watched as someone smoketested an unknown
pipe, and smoke came up alongside a corner of his house, and from a spot in
the garden where there was an erosion path. The unknown pipe was a perimeter
drain pipe, one of two.
I agree, if you are sure they are not sanitary then just leave them open in
the ditch line and bed with gravel cover the pipe ends and part of the
gravel with fabric to make a french drain out of it. Again depending on the
lay of the land, it should work for many many years trouble free.
The proper way to deal with this is to put a sump pump in your
basement. The ends of these pipes should either dump into the sump
pump ir be sealed and another part of the pipe be made to dump into
the sump pit. If these pipes were used to perimeter draining and you
just cap them off, prepare for leaky basement walls and possibly even
foundation damage. Sump pumps were used after they stopped allowing
rain drainwater into sanitary sewers. If they were just old
raingutter hookups, you can just ignore them, but be sure the tops are
capped where the gutters used to enter. That may require some
digging. I never could understand why they ran raingutters into any
kind of sewer, they always seemed prone to clogging and would then
overflow at roof level. In my opinion they are supposed to drain on
the lawn or into a ditch above ground. Yet, for some reason, it seemed
that prior to the 1960s they always did that. I guess no one thought
about all the leaves and twigs that come down raingutters. Heck, mine
clog up just draining onto the lawn, but are pertty easy to unplug if
they have free ends.

Probably go to the neighbors house. Their sewerage needs to go
somewhere too. However there is also the possibility that there used
to be some sort of radioactive leakage under your house and they had
to drain it somewhere. To test, turn off all the lights at night and
see if the liquid in those pipes glow in the dark. Give it a try and
let us know if it does or not.
