Never cover manholes, they are there for a reason.

Post #10, @Hugh Jaleak called it although, I thought manholes had to have an air tight cover fitted.

So im looking to lay porcelain tiles....up until last week, this was covered by block paving. What is best way to proceed?

Look for an appropriate size cover slab for the concrete sectional manholes, most good Builders Merchants should be able to supply. (Measure up and see what size you need.) Remove what is there now, and replace with slab, hopefully, this will give you enough leeway to set an Inset Cover, to allow your tiles to be laid up to, and inside the cover to minimise visual impact.

Secondly, looks like water and waste is discharging from the top pipe, this shouldn't happen, it is likely there is what is known as a 'Backdrop', a pipe dropping vertically outside the chamber, to discharge out the bottom inlet into the channel. Top pipe is the level of the incoming sewer and should be for rodding access only. Backdrop, (vertical section) is blocked.

Only when the chamber is internal. Although it has been known for people to smear manhole frames with a liberal coating of grease or similar, to provide a seal if they are troubled by odours outside the property.
