Firstly, a big thanks to everyone on the forums for your contributions. I've been lurking for over a week and trying to absorb and learn as much as possible. My wife and I purchased an Intex 16' x 48" Ultra AGP recently and are currently preparing the ground near our house. We have a decent grade so it has been a LOT of work to do this manually. We made the mistake of hiring someone inexperienced with leveling work on Craigslist to pre-prep the ground and level it, so we ended up doing a lot of the work ourselves today.
We're almost done with the leveling, but we've currently hit a roadblock... quite literally.
Here is a picture of a concrete block that we unearthed during the leveling process - https://i.imgur.com/AwlrRv8.jpg
I was able to pry it up gently and I noticed what appears to be soft piping (kind of like garden hose piping) running up to the bottom of this concrete block. The green pipe like thing buried in the concrete block appears to be made of plastic. Is this a gas line? I really don't want to do anything stupid, but the local dig number has only ever marked spots in my front yard for utilities. Should I be worried?
Just a bit of background - My property was originally part of my neighbors property up until 2006. Then it was partitioned up and this section (which was the backyard for my neighbors original plot) ended up as a new plot that was developed by new builders. Could this be part of an old sprinkler system? (supposedly there used to be one that ran all the way through our yard)
I'd really appreciate any guidance and help. I don't want to do anything stupid, but I'd like to figure out what this is because I can't really install the pool because of this.
