Introduction
The photograph on this page of Wycombe Marsh: Sewer pipeline by Nigel Cox as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

I am assuming that this is a sewer pipeline because it is heading straight in the direction of what is marked on the OS 1:10,000 scale map as a water pollution control works. The pipeline runs parallel to Image, the embankment of which can be seen beyond. The much smaller upper pipe is probably some form of venting facility. The patch of weedless water with the dark green edging in the centre of the picture was bubbling away and I am assuming that this must be a syphon that allows water to pass under the railway embankment. All this is pure speculation!
