What are them pipes for?

[Kazak]

Was looking at some land for sale and they had 3 of them in a row in the ground.
There has been some digging, earth removal in part of the field, and then hardcore put in..near where them pipes are.
Any idea what they are and more importantly why are there for?

Is there an aquafir running through the area ,,they might be borehole test pipes ,,does the top come of

I'd guess landfill

We have some across our place that are bore holes for testing water quality, they were installed due to the location of a quarry and the concerns over the impact it had on the quality water aquifers. But ours are blue and suspect they are colour coded for water, gas etc possibly?

Could be Piezeometers for checking subsidence or sinking.

HS2 have sunk several boreholes to monitor aquifer levels on my land and they are capped thus.

Could be Piezeometers for checking subsidence or sinking.

these have been dug and placed on sections of railway embankments near us. 3 or 4 in a row in straight lines up and down the embankment or cutting

I had some like that put in land of mine that the council was looking to buy to extend cemetery.

Said it was to check water table level

Such pipes can also be for checking radon gas levels, all development sites have to have a radon report for the planning permission, even in areas where its not a problem.

We have several at present, boreholes checking artesian water levels
