I'm replacing a fence in my backyard. Some of the new posts will not be in the old holes. While digging a new hole, I came upon a pipe which is in the way. I don't know what it is for and I'm unsure if it's safe to put a post next to it.
I can see some hairline cracks in it, which may have been caused by the temporary post I put in next to it.
This is in the Netherlands. The pipe seems grey pvc, at a depth of about 40 cm. Its diameter seems about 40 mm. (which is a standard diameter).
It comes from under my (paved) backyard and disappears under the street. The picture above is right next to the gutter of the road behind my backyard, so it's at the edge of my property. There is no manhole or drain in the road where it could be leading to.
Pipes should be at a depth of at least 60 cm, so that's the first mystery. Gas lines should be yellow, power lines should be red, so it should be neither of those. The rain pipe coming from the roof is wider, so while that is connected to the sewers somewhere, it's unlikely to be connected to this pipe.
It could be drainage, but then I don't know where it's heading.
I'd like to know what this pipe could be, and if it's safe to put a post next to it, possibly putting some stress on the pipe, or what measures I should take to protect the pipe.
In the end, I just put the post right next to it. It's now covered with soil again and paved over.
