A buddy of mine just bought some land just off the coast that has low
water in the summer.  He's got a few wells down about 100 feet
(elivation) below his house for stock water and we're thinking about
putting together a windmill pump to fill his water tank during the dry

At this point we were just drinking a few beers and thinking about it, so
i'm on the big 'windmill water pump' education tour.

The wind there is typical Oregon coast -- if the wind ever stopped
blowing everyone would fall over.

Just checking out the commercial sites like:

I don't think he needs a HUGE one.  Even 100-200 gallons per day on
average would be fine just to keep his water topped off

Just reading how it works:

My buddy is pretty good machinist and has a lot of those kinds of tools
in his shop.  

Anyone found a good DIY guide for building one of these things?

Prices here http://www.deanbennett.com/ .

Not worth DIY IMO. Buying an abandoned one cheap would be more
practical, although it would still be a lot of work to move, repair,
and set up.

Chances are you'll find a solar pump a better choice. Lots of options,
here's something  http://store.solar-electric.com/susdssusopua.html
worth considering if it fits your application. If you can find a used
one they're not too difficult to rebuild. Only one special tool
required and it's easy enough to make.

yeah just from what I've seen it would be a pretty big project.  I do
know of a windmill on another guys ranch that doesn't have the pump part.  
I think he just set it up because it looked cool -- got it somewhere or

Wow those are better than I thought they'd be  -- just now looking over
the specs.  If we can score a solar pump setup that would certainly be
easier than dealing with wind and concrete mounting base for tower etc.

Thanks Wayne

Perhaps the most DIY-friendly wind method of water pumping. Watch out
for the submergence requirement. Still generally not as practical as
solar though.

Lifting 200 gal of water 100ft over 24 hrs is 111 ft-lb/min, about a
1/5th of a HP, or 150 watts continuous. Get a windmill of that wattage
or more and and a 150 watt pump and start pumping.
