While removing earth from my rockery in preparation for building some
steps I have come across a large chunk of concrete. This is
unfortunately in the way and I would like to move it. But I have a
feeling it could be a sewer pipe encased in concrete, does this sound
right?

It is on the same alignment between my inspection cover and my
neighbours. Strangely the concrete is above the level of the lawn but
about 0.75 meters below the path outside my patio doors. Maybe this is
the reason it is protected in concrete? Or are all sewer pipes built
this way?

Thanks,

Graham
