Hi. I was wondering if anyone has any experience with pumping water in an off-grid situation. We have a spring on our land, but it is unfortunately below our house. We want to pump water from the spring to a holding tank up slope from where we can pipe it along to our house. We are off-grid so would have to be without a mains pump.

I would love to hear what other people are doing in similar situations.

You can get a solar pump. Complete for about seven hundred quid. If there's any movement, a ram pump could also work.

We use a pasture pump, but it requires a cow's nose.

I'll find out the solar info when I get home.

We use a Patay hand pump like this to fill a header tank from a well. For 2 people, it takes about 3 minutes, twice a week.

If the spring has any storage capacity I would ditch the header tank idea & use a booster pump with large pressure vessel to reduce pump cycling.

I like this idea. Feels very resilient, although I am not sure if / how it would work in our situation. We need to move the water quite a distance. Something to reasearch more though.

Re solar pumps. Do people use battery storage or just pump directly with the panels energy? The latter is an attractive option but is it realistic in the UK (the websites I have seen it suggested on are American)

I imagine you're probably talking about much longer distances but just in case it helps, we have a second hand pump for grey water and it easily pumps for 25 metres on the flat.
