What is this, Dunmow airfield?
Was out walking around the old Dunmow airfield and came across this. It was positioned at the very beginning of the old runway 22 on the left hand edge, where the perimeter track enters the runway.
The top was removable and you could see down the round circular vertical shaft (about 3 inches in diameter) to about 2 foot where there was some water.
Any ideas?

Judging by the dead grass around it I wouldn't drink the water.
It could well be a septic tank vent dating from the days before it was an airfield. Or a power/communications connection point?

That thing looks in remarkably good condition for something that's been there for over 70 years. Suspect it's agricultural. The vegitation is fine on one side and dead on the other, suggesting something has leaked out to kill it and fairly recently.

Grass killed and top free to move? It's being maintained with weed killer and grease?
High pressure plumbing and you took the cap off? What if thousand-psi water had come out? 4 questions.

It looks like some kind of modern groundwater monitoring point to me. They're usually in a bigger diameter pipe, but the description sounds about right. Are they planning any developments nearby that might need a report?
However the rust on the “cap” leads me to think it has been there for quite a few years
