Oh. I misunderstood you.
I don't see how that's going to work.
A hydro-ram transforms pressure using the "water hammer" to trade
a large mass of low pressure water for a small mass of high pressure
water (roughly speaking).
A siphon that ran that way would quickly run it self out of water, it'd
be like trying to run a hydro-ram on the water it pumped.
except
A siphon works by dropping an equal amount of water further than it
lifts it. But atmospheric pressure won't sustain a pressure
differential
of more than about 15lbs/sq inch, equivalent to a depth of about 34
feet
of water.
To get the water over a hump deeper than 34 feet in a siphon you'd
have to increase the input pressure ie just a vacuum wouldn't do it
without some way to transform the pressure.
I was envisioning some hydro-ram like setup to do that but instead
of trading a larger mass of lower pressure water, using an equal mass
of higher pressure water (the water coming out of the siphon which
is deeper/falling further than the water going in is).
(Just theoretical like, it'd probably be cheaper and simpler to just
use a pump and run it off of the water coming out of the siphon
but that wouldn't be as nifty-simple as a hydro-ram is
