Our neighbor on our east side has a pump house with a 1,500 gallon tank in it, filled with a submersible pump using float switches in the tank to control the level, the bottom outlet feeds a 1/2 horsepower pump which is plumbed to a pressure tank which then provides the water to the house, it's a great setup because the pump house is fully insulated and there is plenty of room to store garden tools and hoses. It wouldn't be all that hard to set up a 12 volt pump run on solar charged batteries for a backup system. If you are fortunate to live on the side of a mountain, as we are, then a gravity system is really nice, not long after we moved to this property we hand poured a 1,100 gallon concrete cistern at the top of our property, it's half way buried in the ground to keep the outlet pipes from freezing and as well with the increase in winter spring inflow it's never frozen in the top of the tank. I am also adding a 1,100 gallon black poly tank along side of the concrete tank, spring outflow was way down this summer and I want more stored water on hand.
