I believe Mollison calls this a "Category 1 Error" and I tend to agree. I love the idea of building say a shed + tank higher up the hill, and then gravity feeding that water down to a house lower down the hill. Simple, low-tech. No need to buy, maintain, replace, or supply energy to a pump...love it.

that could work....if you get enough rain there, but more likely you'll need two pumps. a ram pump for rain events and a second pump to take the water from the lower tank to the higher tank. The simplest would be a windmill attached to the bottom tank.... that you could operate to keep the top tank "topped off". Then you also have an option of generating electricity from the top tank overflow...which could then flow back to the bottom tank. That electricity could even be stored to run a third pump back-up for when there is no rain or wind. That type of system would have multiple redundancy built in, but also require a lot of plumbing and a fairly large amount of water....and investment.
