Strange drain tank?

Question

Possibly the worst photo ever  shows a concrete structure with a square drain cover  in the topbut doesn't show on any mains drainage plans for nearby houses or fora utility search for the land.One of the men who uncovered it said it reminded him in size and shapeof a drain cover.Too cold and horrid to go and take more photos today - but will get aproper look soon.Any ideas?Is it just the end of the drains system that goes the nearby houses?No houses have ever been on the land from what we can see on old maps.

So if it's that, what's likely to be inside? Or will it have collaspedwith age/disuse?

Phil L · Answer

It won't have collapsed or the utility company would have come out and repaired it.I agree, it's highly likely to be gas, or at a push, water.It'll be an inspection chamber for said pipeline

No its not a field drain.Looks like an old septic tank maybe..

Depending on location in the country, it could be a capped off mine shaft...

It looks very similar to two which are in the field at the back of my house. 'Mine' are access chambers to a sewer which runs under the field. [I can see them - and the line of the sewer - on Google Earth. maybe you can do the same?

By being built up, they appear to fulfil two purposes:

They keep heavy agricultural equipment away from the chambers
They increase the level to which the contents of the (frequently blocked) sewer can rise before it overflows

Someone reckons there's a drain across the field ... Will update when we go on field or find out more.(We will have to know what it is I think before we sign a lease forthe land!):)
