Siphoning Well To Pond

Even a perfect vacuum can lift water only a maximum of 34 feet above its free level. The water just boils, breaking the pumping or siphoning action. Your situation calls for 39 feet, which is impossible.

Thanks for responding. Is it possible to change my water level to 34 ft?

The maximum height is ~34 feet; a practical height might be ~30 feet. If you can drill horizontally through the slope to meet your well 30 feet above water, and somehow manage to hook up piping that leaks no air inward; then you can do this by siphoning.

Barometric pressure is the driving force.

P = ρgh

Where P is the barometric pressure at any moment, ρ is the density of water at the measured temperature , g is the acceleration due to gravity at any location and h is the maximum lift available, which comes out something less than the 11.9m requred in this particular case.

Therefore to lift water from the well, one needs a submersible pump with a greater delivery head than 11.9m.
