Fluid dynamics: can you connect 55-gal barrels in series to lawn sprinklers to circulate and keep emergency water fresh?
I saw several Instructables about how to use barrels to collect and store rain water. It doesn't rain enough where I live for this to be practical -- however, I have five blue 55 gal barrels that I use to store water for emergencies. I would like to hook all these together with PVC and run my lawn sprinkler system through them, so that the water stays fresh and drinkable. As it stands, I have to store the water with bleach, and dump it all out every 6 months and start all over again. Big waste, and a bigger hassle. Often as not, I am sitting on 275 gallons of undrinkable swamp water at any one moment in time! -- My question concerns the physics surrounding the fluid dynamics. Is this workable -- running PVC between each barrel in series? -- or does that reduce the pressure to zilch at the end, so pressure wouldn't be high enough to water the lawn and garden? Would you have to put a bleeder valve in the top of each barrel so you could completely evacuate all the air? I really hope someone has actually done this, so I don't waste my time and money making something Mr. Wizard would just laugh at!
