Tanks

The other puzzle so far is the tower along the road from the school facility. A flat-topped cylindrical tower, about the height of the average water tower. Why does the modest array of aerials need so much black pipework? What does the cylinder contain?

A small notice explained that it was not a good plan to get too close as otherwise the amount of electrical activity might exceed safe levels.

We were also intrigued by the bolts tying the thing to the ground, illustrated. Substantial bolts, but would they be enough to hold the tower if, say, it was empty and the wind got going?

Later: further investigation reveals that the tank is a water tank. So the puzzle now is how do they stop the thing freezing & bursting in the winter? We shall have to find a likely looking person to ask. See http://www.dec.ny.gov/enb2004/20040317/not5.html.
