Some information suggests that typical ram pumps discharge approximately 7 gallons of water through the waste valve for every gallon pressurized and pumped. The percentage of the drive water delivered actually varies based on the ram construction, vertical fall to pump, and elevation to the water outlet. The percentage of the drive water pumped to the desired point may be approximately 22% when the vertical fall from the water source to the pump is half of the elevation lift from the ram to the water outlet. It may be as low as 2% or less when the vertical fall from the water source to the pump is 4% of the elevation lift from the ram to the water outlet.

How about a rain barrel with a soaker hose attached?
In any remote water pumping situation, avoid using batteries if AT ALL possible. Your water storage tank should be your battery--that is, your system should pump water fast enough and your cistern should be big enough that you can last through as many days of no sun or wind as necessary
If you go with the barrel idea, you would just let a small pump with
a solar panel attached fill the barrel(s)from the water source(as it would take awhile at low pressure). Then when the barrel was full you could run it from the barrel whenever you needed it directly out into garden.
Unless sprinkling, then you would need a pump for pressure.
Does that make any sense or is this even what you had in mind?

In the OP I mentioned aquarium tubing. That's because I already have a good supply of that that I got for free. It should suffice for a small (10X20) garden.
