Cleaning out the drinking water pools, Mt. Tabor

While on my morning walk around Mt. Tabor, I noticed three guys in one of the empty drinking water ponds. They had powerful water pressure hoses, and they were cleaning out the entire pond, and they looked like little ants in this huge pond. I am still amazed that we can almost walk right up to the place where our drinking water is coming from. Can you see the little man in orange at the bottom of the picture?
