Easily found thanks to OS sketch obtained by TrigJS. Access into compound and onto the covered resr still straight forward. Contentious issue though changing this from Rivet to Disc. The Disc is just a platform for the Rivet, it is the Rivet that the OS surveyor would be using to centre his theodolyte. In addition in the OS archive database it's referred to as a Rivet.

Couldn't find the trig point. Will need to come back with some tools to clear the vegetation and I'm hopefully it could be found. On the roof of the reservoir all the access points into the reservoir have recently been concreted over which will annoy the urban explorers on 28 days later! Revisit 23 December 2018 at 1439 - previously I had been at the National Archives in Kew doing some research and I took the opportunity to source the original OS site file for this trig point. With the details from the file I was able to return and easily find the trig point. Trig point was hidden about 15 cm down under a many years of fallen leaves, plant roots, etc. The OS online trig archive has the trig point logged as a rivet. It is not a rivet but instead the trig point is an asphalt disc. The is confirmed by the original OS marking report (see photos). Currently the trig point is accessible but work is ongoing to install a new fence around the disused reservoir so it may not be long before the trig point becomes inaccessible. Second revisit - 30 June 2019 at 0825 - new security fence still not finished. Looks like a safety barrier has been installed on the corner of the reservoir near to the TP. Update 18/6/23 at 0825 - there is work ongoing at this disused covered reservoir (apparently to convert it to a secure car storage location). When I rode past this morning I observed that a large portion of the roof has been removed and therefore the disc TP has been destroyed.

TP21515 The trig point should be somewhere around here.

TP21515 Update 18/6/23 - disc would have been in the corner of the roof in front of the mast.
