Monday and Tuesday was on an old WW2 Airfield doing test holes/trenches looking for the old drainage system.
This was installed by the Americans in 1942 and site owner wanted to locate the drainage for his new units.
My business contact/friend runs a large grain storage empire.
"I want you do do it Dave because you are careful and methodical"
Grain storage unit in an old hangar in background.
An old plan showed a drain coming across the yard and off the corner under the grass.......
So in this corner went about 2 feet deeper than where I expected it to be - nothing
Looking for an 18" pipe covered in concrete should be easy.
I could see what we assumed was other 18" pipes about 50yds and 100yds across the yard.
BUT access could be gained at only one location. AND couldn't get rods with Sonde up it due to silt and crap
So took the test hole right round the concrete yard......
.....and all I found was the old Communications Ducts
So my friend then says, "OK can you now find the old French Drains beside the old runway?"
"Found it!" - about 2'6" of stone over a nice 6" clay pipe.
So with all these, can you just find this that and the other and various locations, he said, "How long do you need to fill it all in again?"
"At least 2 or 3 hours mate" - for that read about an hour or so at the end of a long day
Fortunately, my friend, was not bothered about the finish because it will soon be turned into a building site.
The old map used was a printout from "Landmark Information" showing "Und Ward Bdy" as the assumed course of the pipes.
Obviously not. I even used Google Earth Pro to roll back the years and look for crop marks to no avail
The final outfall was nearly a mile away across the fields.....
.....and came out with a hoofing great big 3' concrete pipe
Recommended that he gets some drainage experts to do a camera inspection of the course of the old concrete pipes.
Something tells me that I'll be back at this site in the near future
