Will, if I knew that I wouldn't need to worry!
This farm at one period (early 1930's) was owned by Hastings Borough Council, who had water bore holes all over the place piped to a pumping station. In the late 1960's it was purchased by the then tenant farmer under the leasehold reform act. Since then the pumping station, which was excluded from the sale, has gone through several hands ending up now with South East Water. Although the deeds carry some wayleaves for pipes laid over the years the attached plans are not at all accurate, not are they complete.
Certainly some are, in their words, 'disused, abandoned' however equally certainly there is at least one huge pipe feeding three local villages, and I believe another one importing water from Southern Water to SE Water. In places pipes cross streams and are visible, but don't seem to go in straight line so are not following predictable route
Theoretically ALL the pipes (by deed in the way leaves) are deeper than I need to go, however I KNOW that in places they are not
In one case there is a 200 mm pipe in an early plastic so not detectable, however it is one that I know is redundant as it's been cut where it crosses a neighbours ditches.
All a bit of a mess really. At the far end of the field there is a linear undulation feature of raised hump running parallel to a depression - for all the world like a filled in pipe trench that has settled over the years, but local legend says it's the remnants of a horse drawn railway running from a powder mill in my neighbours field (mill stones still in situ) to 'Magazine Farm' about a mile away where the powder was stored after there had been a huge (well documented) explosion. It's a pain in the neck when mowing and I'm tempted to level it with the JCB, but perhaps I should persuade Time Team to look at it and do a geophysical survey of the whole field
