All I can add is that PVC pipe is usually used to house things such as TV cables or telephone wire or non potable water or water for things such as sprinkler systems. Don't know why your pipe has a black cap....are all the neighbours the same.....is this pipe next to the house wall?
Might be an idea to dig down a ways to try and see where this pipe goes.
Sorry I can't offer more.
Let me know if find out.
