4ft drain cover hinders my moat build
Discussion
We await further photos with building anticipation... 
, but if it's full of stones it's probably a soakaway. Don't be fooled by the step (usually provided for man access), it could just be that they used rings at the top that had the step irons already in. If it's a concrete ring chamber soakaway to full depth the lower rings should be perforated.

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.

Yep, that's a surface water catchpit. Could be am overflow for a stream or something. Is there a large-ish drainage ditch within a hundred metres or so? If there was another chamber close by then that should have caught the twigs so I would say upstream is a direct inlet. The pipes look like 9 or 12 inch jobbies so would be for something reasonably substantial. (as in, deep enough to get wet feet)
Personally I don't think the twigs etc in there look like much of a problem, the chamber looks in good condition and no signs of surcharging, the water in the base is a sign that everything is flowing OK. Plastic pipes too, so not that old. If the water board haven't been round looking for it then there's no issues downstream.
If it's not bothering you then it looks perfectly fine to leave and shouldn't give you any problems over the next few years. Getting it moved would make a mess...
Nice one for updating us, it's been an interesting thread!
