Cost effective - read cheap or even free? I plan to draw water from a well with a 110v pump and store it in some sort of cistern. I will then use a 12v pressure demand pump to serve the house. In an ideal world I would mount a 300 - 500 gallon container on a trailer and transport the water in until I get the well down. Then either bury the container or build a structure over it. No current intention of using it during the excessively cold months. So far my best bet is a number of 50 gal plastic drums (which I have) but I would prefer a single container. I have seen the ?300? gallon cube shaped chemical containers with integrated pallets but all have been used to carry some pretty scary stuff! Any ideas??
