In the pavement outside our house is a 200mm square concrete "plug" or
panel in a pavement slab, probably about 50mm thick. Plug is a courser
mix concrete than pavement.
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.

Well cannot see your picture, but Thames Water have something as you
describe every few streets and the can use a kind of water pressure meter
that looks a bit like a bollard which plugs in and one supposes has a
cellular connection so they can track blockages or leaks.
They only use them for a while of course, take that from one who has
collided with many in my time of being blind!

It could even have been a coal hole. Some Victorian houses had their
coal cellars extend out under the pavement, so were filled via a lift
away panel in the public pavement.

Did they drop the coal lump by lump?

That is a small cover.

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....

had a guy in a detached house phone me once that his drains were backing
up...I visited and found he was rodding to a dead end so I asked him to
measure the length of his rods and find the spot where the rods were
stopping ....then I told him to start digging in his front lawn ...some
way down he hit a concrete slab...he removed the concrete slab and there
underneath was the top piece of his disconnecting trap complete with the
blockage....he couldn't thank me enough....

It happens that ARW formulated :
Did they drop the coal lump by lump?

That is a small cover.

They used to be 12" x 12" so not much bigger that the quoted 200mm
square. They would use a metal funnel to guide it in.
