In the pavement outside our house is a 200mm square concrete "plug" or

It isnt mortared in and I could probably lift it out if necessary.
What is it likely to cover ?
Old Water stoptap ?
I would like it to be access to the "drain" which exits our Victorian
terraced house 10m away , taking both surface and foul water, and
connects presumably to the main sewer in the road but which has no
manholes anywhere.

could be the cover for what we call in Scotland a Buchan disconnecting
trap .....if you lift it you will see the 6 inch top piece...but then
again sewer disconnecting traps usually have vented covers so probably
not....
