I see you were able to trace it to a certain point, but it would be great to find the source so you know what you are up against later if there is another failure.

Where does the direction of the pipe after the 90° bend point to?

Neighbor's house?
A low area in the yard?
Another structure?

If it points to a neighbor, how long has that person been living there? The current owner may be clueless about anything a previous owner had done.

There is no way in hell I would tie it into my drain system without knowing the source because if years from now some kind of pollutant flows through it into the creek YOU are going to be responsible for the remediation. Keep in mind the DEP don't play around.

Well interesting developments with the plumber but no answers. Used a camera/sonde setup and traced the pipe about 60 feet uphill towards the house where it makes a 90 degree bend and heads across my lawn in a totally new direction.

Unfortunately the pipe is old and of very low quality materials so the condition is terrible. It is buckled up and down and narrowed in a few spots. Ultimately the camera and sonde were blocked by a collapse although water is still coming through.

The good news is the mystery line is immediately adjacent to my existing system, so a tie-in is possible.

worked at a job about 8 yrs ago and we FINALLY got new fiber installed to alleviate bottleneck issues on our campus. they were like "how we going to run this line?". found that we had an old unused fire alarm wiring system in a 3-4" pipe. even better it runs straight as a shot to our building from maintenance!
so they ran the line until the first juncture box at ground level where it then made .... a 90 degree bend to the left. WTH? ...and proceeded to the next building over into the basement! and then there was an open conduit from that basement into ours. ok, who TH designed this? :headscrat
so we got our new fiber line in but also learned not to make assumptions based on common sense...especially since they had already pre-cut that fiber section to about 1100ft. with the unknown re-direction, they barely made it to the server room to terminate the line.

I can't wait to hear how this "scream test" comes out.

Seriously, we are INVESTED in this mystery. This is bigger and better than Al Capone's vault.
Remember the guy that found the hidden room and tape recording in his attic?

Pick you up a Firnco cap--a big rubber cap with pipe clamp--and close off the end of the pipe the water is coming from. You'll soon enough find out what the source is!

Kinda like a friend of mine who traced the wiring in his house by shorting out an out let to see which breaker popped :0

Beat me to the punch!

Waiting eagerly for the outcome....

Dig and get access to the mystery pipe as far 'upstream' as you/plumber could get to and try tracing further. Leap-frog further upstream as needed to get more into where the pipe and the water are coming from.
I agree. There is no way on earth that I would simply tie that into the other system without knowing exactly where the water is coming from. Thats just asking for trouble.

Well the mystery pipe is now capped at of this afternoon. I guess we'll see where it backs up.
It sounded like from your previous post that it veered off of your property.
I would have done the same.
No doubt that it will eventually cause a problem for someone upstream but you aren't responsible for some agreement that some people made previously.
The only way to really deal with it now is to know the source.

So the plumber only scoped one direction?

At the rate you said it was flowing seems like it shouldn't take long for someone to notice a problem.

The downstream direction was thoroughly blocked because of the cracked pipe and scoping wasn't possible, but I know it ran about another 25 feet to the old muddy spot which was about 20 more feet to the river.

And I am rather surprised that you can discharge into a creek/stream/river (what is it?). Around here that is highly regulated and generally you can NOT directly discharge into a creek/river/stream AFAIK.

That was my thought as well and makes the OP's aversion to asking the city to come out and take a look very well placed.

I still would to have like to know if the water had chlorine in it. As it's clear water and runs near constantly (it seems) a water leak on a municipal main or private service line seems a likely source.

Geez. I’d love to have a water source like that. As long as it was on the other side of my meter collect, it tested and put it in water tank.

A lot of older houses on the street including mine have grandfathered stormwater discharge allowance. That was commonly done for many years because of the complicated situation with riparian rights on the river, to ensure maximum water flow gets in the river and is not wasted in the ground.

I don’t think it’s been allowed since the early 70’s and that’s why I have chosen to cap the mystery line rather than drain it. I don’t want to risk a violation as my existing system is permitted and legal.

So far no backup anywhere, I am watching.

At the farthest point they traced, where does the line point? Off into an empty area or at a structure?

It heads straight for a neighbor's house, but could also just be going around my house if there is another 90 degree elbow.

I like that neighbor, so I had checked if he as a sump pump running (no) and I alerted him to watch for any backup. So far nothing.

Well it's been over a week. No updates of note, no flooding at any neighbor yet. Appears the water flow found another way to go to drainage.

Wondering if one of those ground radar or sonar machines would find or follow it to the source? Like the ones they use to find bodies.
