Hi,
I rolled my sleeves up today and started digging a hole for an in-ground trampoline.
Unfortunately I unearthed a concrete sump/septic-tank/tombstone in the hole, just 200mm deep. See 3 pics:

Our house is on the sewer main, but it doesn't run through that location. It's a 1920s house, backing onto a Victorian Terrace, so could be something old which isn't in use any more.
What do you think this is?
Any advice on what to do? Ideally I would remove it somehow, but not sure if that's possible.
Any suggestions much appreciated!!
Thanks.
