Is this a surface water drainage main access duct cover or a sewer cover?

Bit cross that it wasn't seen on the searches done by my conveyancing solicitor.

Was hidden under 8" of topsoil and a bush.

Ahhh so it's a Nazi bunker cover.

It's a nice new fence wot I built. But the actual boundry is about 2ft behind the fence so the whole thing is on my property. Too many tree stumps to build right up to the boundry line.

A dropped stone indicates a 6ft drop into water underneath.

Moving the cast iron cover may be tricky.

I presume the Council owns it not me so I'm a bit limited as to how much I can 'revise' it.

Thanks for the replies.

I was actually planning to dig out the soil to make a pond.

This is at the side of the house but still within the front aspect.

Plot was a field before houses were built around 20 years ago. I reckon this drain was there before the houses were built and was heavy duty topped for agricultural vehicles. It's right up at the boundry line so it's unlikely that any crops would have been planted that close to the original fence.

Won't be going down it, but I'll probably take the top covers off to check what's down there.

Will post piccies when I've had a look.

Good job I didn't go with plan A, which was to talk myself into hiring a mini-digger to blast through topsoil removal.

Won't be playing again until the weekend.

Before I post photos of this thing opened up all over the [/yank speak] innerned [yank speak] just need to check that I'm not then likely to attract the attention of any jobsworths (plod, HSE etc.).

What's the PH view on that possibility?

Update.

Bit more digging then Mr Bar came out to play.





Looks like the 2 halves are bolted together - bolts look in good condition so I've ordered some lifter keys.





More later.

I don't mean to sound all mumsnet but best to have 2 of you do the lifting when you do pop it, just in case. They're not THAT heavy but if you have to do some awkward manoeuvring then it's a lot easier. Also, lifting alone, when they swing and smack you in the shins it'll bloody hurt... wink
Not mumsnet at all old chap. I value my intervertebral discs.

I've bought these;



Plan is to tie them together when inserted in the cover using a tow rope then pull the cover off with the car.

Getting it back on may involve the use of an assistant.

Sound advice and much appreciated.

Car would be the last resort, but potentially the most fun.

If it can't be lifted easily with assistance, then I may use my scaffold tower base to throw 2 tow ropes over (one on each key, keys firmly wedged in place with hardwood splints).

That would give me vertical lift from horizontal pulling.

The base isn't going to move - I've already tried a few heavy blows using a wooden block and a lumphammer.

Lifter keys arrived, evening sun shining, so playtime ....

1st step was to lock the keys into a wood block to ease lifting, get an edge up and secure



didn't need this baby



closer peek - can see a large surface water drainage pipe entering the manhole and the steps





stuck the camera in - possibly stones in there for a soakaway



I'll get an inspection lamp down there and take more piccies on Friday.

Just looking for my wellies.

And now the final reveal ....









Job's a good 'un.

Looks like a surface water drainage pipe inspection chamber.

2m deep with about 30cm standing water in the bottom.

Not sure if there's pebbles under the water.

Bit of a tree seems to have washed up in there so maybe it's for a brook or stream flood overflow system.
