I'd definitely talk to the waterproofers. They'll be cutting concrete; surely they'll have experience dealing with cast iron pipes (and they'll have to deal with the leftover portion of the pipe in the slab).
do the sawzall routine with a long metal blade. push it down onto the cement to cut it off flush (exactly as shown in top pic). cast iron pipe should be no sweat (bad pun for plumbers!)
You can flush cut pipe with a reciprocating saw and a long blade: It might be hard to get all the way to the wall with this method. They make a special blade just for flush cuts: and although it will go through nails in wood, I don't know if it will cut that pipe. There are other gadgets and adapters out there for flush cuts with recip saws though. ...
The basement drains in my house would also become dry allowing sewer gas to emanate and foul the air. To alleviate the noxious and malodorous gas I have written on my weekly chore list to "run water in all traps". I've found this to be a successful way to stop the stench from the drain.
I had something similar last year after movie into a new house. Long story short, the smell traced to a dirty trap in an upstairs shower. I used a soapy paint roller to scrub the drain.
If you are not using the drain at all, I've heard of people poring oil down to replace the water as oil dosn't evaporate. Obviously use an oil safe for the system (not motor oil) and something that won't smell when it gets rancid. I suspect the cheapest vegetable oil you can find would work. https://en.wikipedia.org/wiki/Trap_primer#Other_solutions has ...
You can use something like the non-toxic RV antifreeze which evaporates more slowly than water; Or wash the basement floor occasionally. A touch of mineral oil (the stuff sold for putting in people) may help to prevent evaporation by forming a surface film, but don't overdo that.
Thanks everyone for the feedback and tips! Turns out I was able to get a clear answer by calling the sewer company: 1) They looked at their recent scopes and confirmed that our property does indeed have two sewer laterals. They also observed some corrosion and decided to come out and take a look. 2) They brought a truck out to our house and performed a ...
Near the sewer main you may find a bidirectional cleanout, and be able to observe the sewer flow. Go upstream and dump dye into the water (Fluorescent Green Dye for example) and see where it comes out. Special purpose dye is available, or just use food coloring. With a house that age anything possible, except water running uphill.
