What can I do about this manhole (*inspection chamber)apart from moving it?

[tmasa]

Have this abomination in the middle of patio, about a brick high from tile level.

Can I chisel off the surrounding concrete and fit a small round table or cover over, does concrete ring have any functional purpose?

Wooden decking over with access door ?

I assume lowering it may be expensive?

The concrete ring is probably the biscuit. Chamber likely concrete rings. Not too dificult to cut down with care, but is it your chamber or public? Ie does it serve othe properties@ if it does you should sttrictly be getting water co permission.

Lift the cover and have a proper look

Replace it with one of these then fill with matching pavers or chippings etc.. https://www.google.com/search?sca_e...UEAHRNyF_cQ1QJ6BAhGEAE&biw=1470&bih=807&dpr=2

Not sure how to identify, there is a brook at the bottom flowing alongside neighbouring houses. Does not look like any part can easily be cut off to reduce top height.

Not sure I follow, it is all round shape and raised (I posted second picture what is inside)

I posted another picture above. To me it looks like concrete at the top can be removed without consequences. Then it might also be possible to replace the orange section with something lower, depending on how it is secured to lower rings?

Update: looks like the topmost ring is plastic and I should be able to lower it myself, what tool do I need here to make a cut on the same level without taking the whole ring out?

Avoid all the industrial work by removing the loose rocks around the cover and replacing with decorative slate or gravel, then find a suitable planter to fit atop the cover and fill with a collection of flowers or a bush at your leisure.

A grinder with a cutting disc maybe? If it’s in soil where you are cutting, maybe drill a hole to start and use a jigsaw.

If it's a shared drain, get in touch with utilities company, they will do it for free IF it's shared

That is how it was so far, something on top. But I need this area flat without tripping hazard. Removed all concrete skirting already, all went off after one sledgehammer hit. Not sure why it was needed at all, the riser is quite sturdy on its own.

Don't have it but will probably get the Lidl one, should be enough for the job. I don't think I can take the riser out, so plan to clear the surrounding soil, fix a bin bag with gorilla tape inside to avoid debris falling down and then try to stick to the line to make a straight cut.

Do I need some kind of sealant after, maybe the reason it is raised was to avoid rain water / soil getting in .. but then these are normally with lid on surface level, perhaps was just a lazy job by original builders.

It might be, but Google says -

Manhole covers
If the manhole cover is in your property boundary, it's your responsibility, if not, it's the water company's responsibility.

It is in my garden, may be less hassle just to do it myself, not really broken, just inconvenient.

Well worth a shot.
We had a pattern imprinted drive installed, we have an open driveway between us and next door neighbour, the manhole for both properties is on our drive and is shared manhole

With United utilities they have policy, that if it's shared they will fix everything to do with that manhole, even blockages.

They fixed our manhole when the Donkey who installed our drive thought it would be a good idea to replace a concrete lintel with some 4x4 softwood.
