I have the following manhole cover in the middle of my front garden and it is becoming hazardous as the cover has become so brittle and loose that if someone steps on it I am worried they will fall through!
With this in mind I looked to replace, due to it being in the middle of the garden I thought I would look to replace with a recessed cover and put grass over the top but the more I look it doesn't seem to be in use and am wondering if I would be able to fill and turf over the top? Would anyone be able to tell of this is still in use or how to find this out and whether or not I would be able to fill it and turf over?
