Do you know what it 'was' before the hole was put in to it? What kind of purpose did it provide before it was adapted?
Does it go in to the sewer or is it surface water?
From the brickwork, it looks like a Victorian / older property.
Which usually means that the surface and sewer water go the same way anyway.
