Water is essential to all life. The human body can go three weeks without food but only three days without water before completely shutting down. Yet most of us find it much easier to store a year’s worth of food than a month’s worth of water. I live in the suburbs and while I have my beans, bullets and band aids pretty squared away, water has always been an area of concern for me. There is no way to store enough water for a long term outage, and I haven’t found many good options. Recently I have spent more time thinking about this and testing possible options. This article is the result of that.
Water Needs
People need around 1 gallon per person per day just for drinking. For a family of 5, that is 5 gallons per day or 150 gallons per month. At 8 pounds per gallon, that is 1200 pounds of water for the bare minimum for just one month. A year’s supply would be nearly 2000 gallons and 7 tons of water. And that is just the minimum for drinking. Water is also important for sanitation, cooking, flushing toilets, watering gardens, fire fighting and many other things. In our modern world, with water available at the turn of a tap, the average American uses from 60-80 gallons per person per day. In a SHTF situation, we would need to be careful with our water use and try to limit the waste but the true need is likely many times the 1 gallon per day commonly quoted. Realistically, 5-10 gallons per person per day is probably closer to what you need. At 5 gallons per day for a family of 5, that is 9,125 gallons per year or 73,000 pounds. From a storage perspective, this is 1,220 cubic feet of water. That is a cube 12 ft by 12 ft and 8 ft high. That would completely fill a medium sized room from floor to ceiling. Obviously, this is more than the average suburban homeowner can store.
Modern water systems
In my suburb on the outskirts of Minneapolis, our water is pulled from a well over 400 feet deep. Pumps driven by electricity pull water from the ground up to surface level. From there it is chemically treated and filtered to remove pathogens and other contaminants. Then it it pumped into water towers placed around the community and from there, gravity takes it into our homes. In normal times, this means that every time I turn on the tap, step into the shower or flush the toilet, a large, modern system brings clean water right into my house. But if that system fails, we need another way to procure this life-giving resource.Continue reading“Water in Disasters: A Rain Catchment and Treatment System, by Suburban Prepper”
