A built on site ferrocement tank with a 1/2 horse 120VAC pump and a 200 gallon or so pressure tank is a very sensible set up. There is simply no way to build large containers cheaper than with ferrocement, and in many ways, difficult to build better. My experience with ferrocement comes from building and repairing cruising sailboats, but there is no difference in building a bowl that keeps water out as opposed to keeping water in. It's an uncommon skill anymore, but very very practical.
