Is Rainwater Collection Illegal?

Is the harvesting of rain illegal? The internet seems to think so, at least some parts of it. For clarity, when I say “harvesting of rainwater” I am referring specifically to the collection of rain falling from the sky before it hits the ground, not taking water out of an aquifer, reservoir or anything else.

If anything was ever going to be free for the taking, it should be rain, right? Maybe not.

Is harvesting rainwater illegal in the U.S.? Some states do have laws prohibiting or restricting the collecting of rain water, that much is true.

However, many states have no such laws against it or actively encourage citizens’ self-sufficiency to ease the burden on public utilities, the rest of the story is somewhat more complicated.

Hey! You got a license for that rainwater?!

Right up front, yes, most states allow you to collect rainwater with little to no regulation.

Some states have cursory regulations regarding how your collection system must be installed and approved, as well as what you can or cannot use the water for, i.e. for drinking and hygiene, or just for irrigation and cleaning. Even with these “minor” restrictions, it is a troubling thing for preppers.

You see, the government, at all levels, already interferes way, way too much in our lives as it is.

We get taxed coming and going, and there are just so gosh-darn many laws and regulations on the books at the federal and state levels that we are all, effectively, criminals in waiting.

The system has just sort of reached an equilibrium where by policymakers, law enforcement and courts don’t have the elbow grease or more importantly the cause to cart us all off to jail.

I don’t know about you, but that is a bum thing to live under. That a government would regulate, in any way, what you with water that you collect is mind-blowing. Now, minor aside out of the way, let’s look at the state of things when it comes to collection of rain water in the U.S.

States’ Issue, not Federal

There is no federal level prohibition against the collection and storage of rainwater, thankfully, though in these times who knows how long it will be before that changes.

Instead, some states have taken it upon themselves to impose onerous regulations against citizens trying to collect rainwater.

Some of this has actually resulted from the largely erroneous belief by people who should know better that the catching of rainwater will actually affect the hydrological cycle of the land, meaning it will impact how much water actually gets flowing into underground water sources.

Of course, anyone with even a cursory understanding of the factors at play would see immediately that the self-same water caught when it rains would eventually make its way to the same place after it was used. Because duh.

At any rate, scientific inquiry in the matter found no amount of catchment today has any impact on our water tables, springs, and any other ecologically important sources of water.

Previously throughout U.S. history there have been similar laws in place to restrict or prioritize water usage, and these were known as ‘prior appropriation’ laws.

Not entirely germane to the conversation, but worth noting since the prior appropriation laws served citizenry on a “first to claim” basis, versus the government just wholesale smashing everyone equally.

Rainwater Collection Laws State to State

Below is a list of all 50 states and a quick recap of their rainwater collection laws and regulations at the time of this printing.

It is comforting to know that most states are moving to more and more permissive rainwater collection laws for citizens, but that is far from uniform.

Additionally, some states take an opposite tack and force you to undergo inspections and certifications before you can catch rain, or make you install an engineer designed and approved system.

CAUTION: State laws change regularly. This article is not legal advice. The author is not an attorney. You must consult an attorney as part of your preparations before installing or utilizing any rain catching and rainwater storage system.

Alabama: Legal on private property and considered a right. Collection is encouraged.

Alaska: Completely unrestricted, groundwater collection regulated. Rainwater collection and storage is primary water source for many citizens.

­­­­­Arizona: Legal, but currently undergoing enhanced study and scrutiny as to its effects on water rights. Some municipalities may establish funding for private rainwater collection systems.

Arkansas: Some restrictions. Allowed to harvest rainwater for non-potable use if system is designed by professionally accredited engineer, and has contamination safeguards installed. Also must comply with Arkansas plumbing code.

California: Legal to collect rainwater so long as in compliance with state Water Resources Board for specific purposes.

Colorado: While historically highly restrictive, Colorado has recently come around on rainwater harvesting. You are allowed to capture two barrels worth of rainwater totaling no more than 110 gallons and only for use as an irrigation source. Still pretty restrictive, it seems.

Connecticut: No restrictions on rainwater collection.

Delaware: No restrictions, actually sponsors collection initiatives!

Florida: Rainwater collection encouraged. Features tax incentives in several counties.

Georgia: Collection is tightly regulated, legal for outdoor use only.

Hawaii: Collection strongly encouraged. State Dept. of Health and Safety oversees.

Idaho: Collection of rainwater legal so long as it has not already entered waterways.

Illinois: Legal but regulated. HOAs may determine if allowed, and, if allowed, its design and where it is to be located.

Indiana: Collection is legal and encouraged.

Iowa: Collection is legal.

Kansas: Legal to collect rainwater if permit is obtained and water is used for anything except domestic purposes.

Kentucky: No restrictions.

Louisiana: Collection is legal, but large storage tanks are regulated.

Maine: Collection is legal.

Maryland: Collection is legal and come municipalities offer incentives for citizens to collect it.

Massachusetts: Collection is legal.

Michigan: Recently passes legislation makes rainwater collection legal and encouraged in Michigan.

Minnesota: Collection of rainwater is legal.

Mississippi: Collection of rainwater is legal.

Missouri: Collection of rainwater is legal.

Montana: Collection of rainwater is legal.

Nebraska: Collection of rainwater is legal.

Nevada: Regulated; while water rights include the collection of rainwater, it requires a grant, and you must use the rainwater for the purpose declared or your grant can be revoked, abjuring your right.

New Hampshire: Collection of rainwater is legal.

New Jersey: Collection of rainwater is legal.

New Mexico: Legal and highly encouraged by state body.

New York: Shockingly, rainwater collection is legal and encouraged.

North Carolina: Collection is legal, but Dept. of the Environment ensures “best practice” for rainwater reuse…

North Dakota: Collection of rainwater is legal.

Ohio: Collection is legal, but regulated by Ohio Dept. of Health for typical residential systems.

Oklahoma: Collection of rainwater is legal.

Oregon: Legal to collect and store rainwater, but only if caught by rooftop direction systems. Caution- seek legal advice.

Pennsylvania: Collection of rainwater is legal.

Rhode Island: Incentivized and encouraged by the state in the form of tax credits.

South Carolina: Collection of rainwater is legal.

South Dakota: Collection of rainwater is legal.

Tennessee: Collection of rainwater is legal.

Texas: Collection is legal, but some regulation in place. Collection system must be incorporated into building, and local government must be notified of your collection activity.

Utah: Legal, but registration required if you wish to store more than 100 gallons across two containers.

Vermont: Collection of rainwater is legal.

Virginia: Legal, and tax incentivized.

Washington: Collection of rainwater is legal.

West Virginia: Collection of rainwater is legal.

Wisconsin: Collection of rainwater is legal.

Wyoming: Collection of rainwater is legal.


Rainwater collection is legal for the most part, but plenty of states are either entirely too interested in who is doing the collecting or already mandate some odious regulations.

Regardless, you as a prepper should be up to speed on rainwater collection systems and protocols and do so as often as you can.

  1. So why does the Beatles, I’m the taxman, come to mind?

    “Should five per cent appear too small
    Be thankful I don’t take it all
    ‘Cause I’m the taxman, yeah, I’m the taxman
    If you drive a car, I’ll tax the street
    If you try to sit, I’ll tax your seat
    If you get too cold, I’ll tax the heat
    If you take a walk, I’ll tax your feet”

    Just sayin’

  2. the thing about ny and why it legal is that we have too much of it most of the time, in the cities rain has nowhere to drain off easily, it can’t soak into the ground so it ends up flooding unless allowed to flush into the sewar system. and half the year its frozen rain that just sits there and there is no place to plow it or move it. 2 inches of snow in the city is a catastrophy that shuts everything down, upstate we don’t even bother shoveling that much.

    the mountains (adirondacks) are historically called the abspestos forest, it rains so much nothing can burn, the only big fires date mostly to the old days when coal fired trains were all over and used to haul logs out (most mountain trails are defunct rail beds or logging roads), back in the old days huge piles of slash, no tree cover at all, and hot smoky coals flying off the trains caused the forest fires, these days its rare to see a serious fire at all, go walk in the woods and its all damp, foggy, and funji are on everything.

    rain in ny is so common there is no point in regulating collection, in the city someone with a few barrels to collect rain is mitigating a problem not stealing from the public

  3. As for my state Washington, it depends on the county, the one we reside in your only allowed 2 rain barrels, each home, and depending on the weather conditions, I don’t collect it unless we are in for a hot and dry summer, so far i haven’t collected any we’ve been to rainy, so mother nature, does my watering job..

  4. When my son left Npa vine Wash, three yrs ago, he said the state was thinking or or was going to install meters on all cisterns that collected rain water. Have they done yet, good question . don’t know

    • alfie,
      I have also heard/read, that depending what State, they would like to impose a meter reader on a person’s own well….and charge accordingly for water consumption…..
      Total Insanity

  5. In NJ, our lefty governor signed a bill a couple of years ago to fine homeowners or companies who have too much land covering concrete or blacktop driveways. Haven’t heard much since. They’ll go hot & heavy once the state needs more money to blow on their corruption.

  6. are you serious ? Water sky and some other things are free, cannot be restricted. How can people agree with those restriction?
