People ask me all the time about how I purify my rainwater and also come to me seeking advice on how they can purify their own water. So, here’s my answer!
I simply collect the rainwater that falls onto the roof of my tiny house with a gutter that directs the rainwater into food grade 55-gallon drums. These I purchased on Craigslist used for $25 each. Rainwater harvesting is as simple as putting a bucket under your downspout or the roof drip line and letting the rainwater fall into the buckets. Truly that simple.
