Stand Alone Rainwater Harvesting System
Is Rain Safe to Drink?
Posted on December 15th, 2009

The short answer is “yes” as long as it is caught and stored cleanly. Rain is actually the purest form of naturally occurring water because it comes from the natural process of distillation. Rain only becomes unsafe to drink when it comes in contact with harmful substances in the air, but this can be avoided by not harvesting the rain during the first few days of the rainy season. By the third or fourth day of rain, much of the potential pollutants have been washed out, resulting in rain that is fresh and hopefully pleasant tasting.

To prove that rain is safe to drink, we will be incorporating a “taste test” into the series of tests we plan on running on our prototype. We’ll post the results here along with any other tests we are ready to publish.
