Down under we are a pretty dry country.......... most older rural properties have house hold water from roof rain water feeding into large Galvanised Iron water tanks adjoining the house. These are typically 5,000 Gallons or more in capacity. And a single house may have 2 or more of these tanks in series for domestic consumption. Live stock will drink from dams or water bores.............newer rural homes usually have a single inground concrete tank of up 40,000 Gallons capacity and the house built over the top of it...........poly tanks of up 5,000 Gallon capacity are also now used. Im curious as to what the situation is in rural parts of the US? How do you store water?
