Pumping Water About 20 Feet Uphill Cheaply?

[LowGear]

I've got this cistern.  It's on a high point of a five acre farm.  The roof that covers it is only 900 square feet so I harvest water off the garage roof as well.  The mauka (East) side of the garage roof works pretty good.  But the Makai (West) side is about six feet lower.  Hence its more challenging to get the water up to the top of the cistern which is about sixteen feet higher than the makai side of the garage where the sump resides. 

Cheapski sump pumps just won't cut that sixteen foot lift.  I'm looking for suggestions to make this cistern fill from the mauka faster and to fill at all from the lower makai side.

Anyone got a butt kicking pump (solution) they'd like to recommend?

I have a pair of these plumbed together for my "shop" water supply:

I just have it sitting on top of a 55 gallon drum that it draws out of. I don't know what the max height is, but 16' should be no problem.  It will shoot a strong slug of water out of a 3/4" hose.

The pressure regulator thing that comes with it is crap but the pump itself is as good as any other for twice the price and you can use whatever kind of pump control you want...

They regularly go on sale for $99....

Thanks for the link.  That's a nice price and I've thought about swimming pool pumps as old fashioned ones are being dumped around here in favor or variable speed.  I think it may be a false economy as not many folks in this area can repair a solid state controller.  I'm more of a $40 timer guy.  I'll check out their lift and volume charts tomorrow.  The other problem is that I'm wired for 120 volts.  I didn't understand the science of moving water when I wired.  I'm starting to figure it out.

I'm plumbed at 1.5" for the first 10 feet and then 2" for the last 6 to 8 feet.  The sump pumps that talk about 20 to 30 feet lift are not bashful around $300+.  I am.  I'll bet today I could have moved 100 gallons a minute for about three minutes.  Hence the 2" infrastructure.  Anyway, this site is for hardware overachievers.  I have at least two pump stations that require this big time pumping.  I'll be dreaming of those industrial diaphragm pumps for the next few nights.  We're having one of those 10 minute 100 GPM rain storms as I write.
