i bought one from a local guy in sheridan for 65 bucks i think. its awesome as a rain barrel and is working great for me. if they are cheaper than 60 usually they aren't the food grade on craigslist. just a heads up as i looked for ever. you will have to get a 2 in to 1 inch reducer and then put a garden spigot on it to screw your hose in but its easy to find at lowes.
How long did the rain water stay fairly sanitary in your water tank? Since I will mostly be using mine for the garden, I wouldn't want to treat the water.
your good if its just watering your garden or flushing the toilets, your good to go. it will last 3 months or so and since its a clear plastic totes, if you leave it in the sun it will purify the water. they have ben using this technique for a bit in africa. it will take a bit longer here in america and depends on the amount of sun it gets.

I would really like to pick one of these up for rainwater.
How do you purify that much water for storage? Pool shock?
