Hello all. We have a slight problem that seems to be getting worse. Our sewage line, exits through the basement wall and leads to the septic tank. Before it hits the wall, it transitions from PVC to cast iron. It's then a cast iron pipe from there, to the tank. My question is, based on the images below, do you guys think that somewhere the pipe has a leak or is it possible that ground water is just seeping in around the pipe? In either case, what sorts of solutions do I have? Sorry for the quality of the picture looking into the pipe. The wall makes it look like water is just flowing out but it really isn't. Today is probably the worst I have seen it and right now it's damp on the concrete floor. Luckily, this slopes slightly to the sump pit.

While removing some over-grown grass by my well casing today I just about died when I found a grey, flat hard plastic strip with the end cut clean off and seemingly running towards the well. I found it while pulling up on mounds of roots, and the only shoveling I did was to skim the surface beneath the roots themselves after slicing down into the ground a good foot away from the well casing itself and only pushing about four inches into the ground. My water still works hours later, the breaker did not flip and I have 40 PSI in the tank. I ran the water for a good 10 minutes after words while I cried a little. It dropped to 20, rose to 50, and has now been at 40 with normal water usage since. There are no wires visible on this plastic strip where it was cut, it is about a half inch wide and flat, and looks to have been cut with a utility knife. (I did a cutting test with the same shovel on an old phone charger cord to see if I could get a clean slice like the one on the plastic strip. Couldn't even cut the cord with the shovel.) I also dug away from the well casing with my hands to see if I could locate the other end (if there was one) with no luck. What is this thing? I'm really crapping my pants thinking that I've ruined something, however there seems to be no way that I could have possibly sliced it with my shovel. Any ideas?
