Collecting rainwater seems like a no-brainer. That water’s free and falling from the sky, so why not put it to use? But some states restrict who can collect rainwater, and how much they can collect, for a number of reasons, most of those being environmental concerns. That’s why we're here to fill you in on those reasons, show you where rainwater collection is restricted, and give you a quick primer for collecting your own.
Quick Look at Rainwater Restrictions
Collecting rainwater is often restricted for environmental or health concerns, as it extracts vital water from the ecosystem, and that water is often unsafe to drink. Sometimes, water rights laws dictate who gets to use certain water sources.
Steps
Collecting Rainwater
- Check your local laws and regulations. State and local laws are always changing, especially in this age of a rapidly shifting climate. Even if you’re fairly sure about your local laws, take a minute to check the official FEMP Rainwater Harvesting Map to ensure it’s legal to collect rainwater in your area, or learn about restrictions specific to your region.[8]
- Place a barrel under a drainage spout to collect non-potable water. Collecting rainwater for purposes other than drinking is a cinch. Simply acquire a large barrel, preferably with a lid made for rainwater collection, and place it under the drainage spout of your home’s gutter, on a level and sturdy surface.[9]
- Use non-potable rainwater to wash your car, water your garden or lawn, clean your tools or outdoor gear, or any other purpose aside from drinking it or applying it to your skin.
- Many states or counties that encourage rainwater collection sell their own rainwater barrels. Consult your county agricultural office for similar opportunities.
- Filter and purify collected rainwater for drinking. Drinking rainwater is rarely recommended, but can be done by first filtering it to remove any contaminants. First, run the water through an activated carbon filter to remove particles, boil it for at least a minute to kill germs, then test it with a home water kit to ensure it’s drinkable.[10]
- Or, you may neutralize bacteria with 6–8 drops of unscented and uncolored chlorine bleach for every 1 gallon (3.8 L) of rainwater.

- Note that most rain barrels are only made to hold water for a few days. Otherwise, it may attract harmful bacteria or mosquitoes.[11] Empty and scrub your rain barrel every 2-3 days to keep it clean.Thanks
