I use recycled containers, primarily plastic, ranging in size from one to five liters, and spot them in various locations around my property. I want large numbers of small containers rather than a smaller number of large containers because I am concerned with earthquakes, which I feel could rupture or puncture a large container during building collapse, etc., so that I will have more water available with smaller units.

And you are right about plastic containers clopping the world's beaches. They are commonplace everywhere on the channel Islands
