Very high head pumps (330ft+)?

[Philip Levin]

We want to pump water 330 vertical feet up a hill over a pipe distance of ~3000ft. Flow rate doesn't matter (we'd only use it occasionally to fill a tank on top the hill). Source is a pond.

1) Are there (affordable) single water pumps that can do this kind of head? Does anyone have links they can provide?
2) Also, what kind of pipe should be consider for this distance?

You also want to consider GPM.

What is the source? A cistern, pond, city water pipe?

Will the pipe be buried? How deep?

I would be thinking ASTM D 2239 poly. Poly has thermal considerations, but not as much as PVC. http://www.charlottepipe.com/Documents/PL_Tech_Man/ExpansionandContraction.pdf

In addition to head, you have friction losses. https://www.engineeringtoolbox.com/pe-pipe-pressure-loss-d_619.html As you see, flow rate is significant.

Source = pond
Pipe will be buried 1-2 feet. This is Northern California so weather is pretty mild.

Thanks for resources on friction loss.

What will control the pump?

What happens at the output end?

Pumps feeds a water tank on top of the hill.
Can be controlled manually (turn on / turn off)

Intermediate, where you hook the pipes together with barbed connectors or tees, you could put in a yard hydrant for utility use or testing.

Submersible 5 gpm 3/4 HP pump in the pond roughly horizontal. Best to power via a GFCI. Use a flow inducer sleeve or run the 4 inch pipe all of the way to the bank if you like. Use wire cage to keep fish and weeds out. Maybe two stages of coarseness. Don't use a cartridge filter that could clog. That's just an example. Grundfos 5S07-18 is such a pump.

That would give about 6 gpm, and that would be more than enough for a very large house and more.

I think a vacuum breaker may be needed near the top. That would admit air to prevent a vacuum that could collapse the pipe.

I am not a pro.

Thanks - great answer. If we didn't want to use a submersible pump and instead wanted to pump from a water pipe, would we have any pump options?

Pump not elevated more than about 9.5 ft from the lake surface...

Maybe something like one of these.

You would need to to go through the numbers better.
