I lived off grid in the desert once.

Had a 1200 I think gallon water tank.It took care of me for food,bathing drinking and a pack of mutts for three months.

I currently have ONE 55 barrel,and many 1 gallon waters.

Have 2,new 55 barrels on order from store.

Add 2 cubes of 275 gals,(thats only 200 bucks) and I would have 700 gals. Thats a good amt.

Space/wt is important,I have a place in yard that could easily hold 5 cubes protected.

So its time we got our water a little more under control.Wake up call for me,for first time in 15 years creek by me had no water when I checked a week ago,yikes!I thought it was always good,next closest is about 1.5 miles away. Hmmmmm.....still need that solar powered golf cart I see...

I too have a cool siphon for barrels.
