Because You Asked: Can I Drink Rainwater?

Written by Recyclebank .

Safely take advantage of a free natural resource: rain.


Dear Recyclebank,

Can I drink the water I collect in my rain barrel?

-Ana, Carson City, NV

Dear Ana,

Rain barrels are fantastic tools for making the most of the free water falling from the sky. Diverting rainwater into a barrel helps manage stormwater run-off, and rainwater especially benefits plants because it’s softer (lacks metals) and doesn’t have the chlorine of treated water.

However, it’s risky to drink water from a rain barrel. Many rain barrels catch the water that rolls off the roof and down a gutter, and in the process, visible and microscopic contaminants can get washed into the barrel. Bird and insect feces, chemicals leeched from roofing, mosquito larvae, and pathogens can render the water unsafe for drinking. The CDC notes that simple water treatments — such as boiling or adding chlorine or iodine — aren’t sufficient to fully disinfect and filter rainwater for human consumption.

As pristine as collected rainwater might look, it’s probably only safe for outdoor uses such as hydrating plants or rinsing off a sidewalk. But even for these uses, you should take steps to protect your rain barrel. Keep it covered and drain it regularly to prevent mosquitos from breeding. A cover will also keep out debris that could clog the valve.

    I have 3 rain barrels. Most summers, they provide all of the water needed for my vegetable garden and potted plants. Love it!

    I haven't began harvesting rain water yet, but I plan to put a rain barrel (homemade) on the side of my detached garage this year so as not to harm the foundation of my home or gutters.. I have already made a compost bin (homemade) ... GO ME!

    I use it for my plants and try not to throw any of it out.

    Two very good things to do with rain water are to water your house plants and to use it to rinse conditioner out of your hair. People believe that toxins in the rainwater will be harsh on your new color, but it isn't. It's natural!

      For most magazines it may take up to 6-8 weeks to receive the first issue.

      You have to be certain that you follow the prompts through your registered email as well... they don't just process by clicking 'get reward'... also, make sure you recycle the magazines when you're finished!!
