Collecting rainwater for drinking purposes may seem simple enough, but there are many ways it can go wrong – some of which can actually be quite dangerous.
If you would like to start collecting rainwater in a way that is both safe and effective, make sure that you avoid these common rainwater collection mistakes.

Mistake #1: Using the Wrong Container
While there are plenty of containers that are capable of holding water, not all of them are suitable for collecting and storing drinking water. Some containers may leach dangerous chemicals into your water, while others are not opaque enough to block out the sunlight – which could encourage algae growth.
Dark-colored plastic barrels are ideal for collecting rainwater, but many other containers will work so long as they are large enough, opaque enough, and not coated with any chemicals that could leach into your water.
Mistake #2: Forgetting to Make Sure it is Legal in Your Area
Believe it or not, collecting rainwater is not completely legal in all fifty states. Several states have decided that rainwater is community property and not something that can be taken by rainwater collectors.
In other states, collecting rainwater is legal, but there are certain restrictions. In Kansas, for example, you may be required to apply for a permit before you are able to collect rainwater.
If you want to make sure you stay on the right side of the law, check your state’s laws and regulations regarding the collection of rainwater before you begin. Read this article to find out of collecting rainwater is legal in your state.
Mistake #3: Not Collecting Enough
Most people don’t realize how much water they use until it becomes scarce. It takes a lot of water to survive, even if you start skipping showers and laundry day.
If you are building a rainwater collection system for the purpose of disaster survival, be sure to calculate how much water you are going to need and how much your system is going to collect.
If you don’t, you may end up with a system that does not collect nearly enough water for you to live on. The more that you are able to collect, the better – in a disaster scenario, there is certainly no such thing as having too much drinkable water.
Mistake #4: Not Letting the Rain Rinse Your Roof Before Collecting It
When the rain starts to pour, many people start collecting it right away. However, it is essential to let the rain rinse your roof for at least ten minutes before you start collecting it.
The reasons for this are obvious when you think about it. Dirt, plant material, feces, and all kinds of other debris gather on your roof, which means it will gather in your water too if you don’t give the rain a chance to wash it away.
Mistake #5: Not Purifying Your Rainwater Before You Drink it
In theory, rainwater is completely pure and safe to drink. However, that assumes it doesn’t come in contact with anything before it lands in your collection barrel. In reality, your rainwater may be coming into contact with all kinds of unsavory things on its way down your roof and into your barrel.
The chances of getting sick from drinking rainwater that you collect may be slim – much slimmer than drinking water from an unknown stream or pond – but there is still a chance.
To avoid this risk, all you need to do is purify your water supply. It’s a simple precaution that could save you from a lot of misery and one that may even save your life.
Mistake #6: Purchasing a Rainwater Collection System
Unless you have loads of money to throw away, purchasing a pre-made rainwater collection system is a waste. Making your own rainwater collection system is fairly simple, and the instructions for doing so as well as the supplies you will need are both cheap (if not free) and readily available.
Pre-made rainwater collection systems, meanwhile, can cost upwards of $1000. There’s simply no real reason to spend that kind of money for something you can do yourself in a day’s time.
In fact, with a little time spent searching, you can likely find all of the supplies you need – including collection barrels – for little to no cost at all, and building your collection system once you have the right supplies is a simple project.
Mistake #7: Not Using a Collection Screen
If you plan to use the rainwater that you collect for any purpose other than watering your garden, a collection screen is essential. Simply putting a fine, wire mesh screen over your collection barrel will allow the water to pass through while blocking out unwanted debris such as leaves, dirt, bird poop, and more.
If these things don’t sound very appetizing, be sure to put a screen over your collection barrel. In addition to a mesh screen, you can also use fabric sheets or even a layer of cooking oil to filter the water that goes into your barrel.
Mistake #8: Not Setting up a System for Getting Your Water Out
Sure, it’s possible to dip water out of a collection barrel using a cup or other small container, but there are more efficient ways to access the water you collect. Installing a spigot on your collection barrel is something that doesn’t take a lot of time, and it will likely save you a lot of time and hassle in the future.
If you want to really boost the amount of water that you are able to withdraw, you can even install a pump in your barrel. Small pumps are not as expensive as you might think, and they can make drawing large amounts of water from your barrel a breeze.
Either way, just know that there are better ways to go about getting your water than dipping it out of the top of the barrel.

Try to locate your tap at-least 6″ from the bottom of the collection barrel to avoid sediment. Also consider expending your downspout collection tube about 6″ below the tee to your barrel, junk gets trapped at the bottom. Use a twist off cap to clean the tube.

Bought some 55 gal. plastic containers from our local Pepsi Co. real cheap. Takes some effort to get the smell of whatever syrup was in it.

i have a 400 gallon underground poly tank . in the basement is the shallow well pump , pressure tank and water heater . ive been using the system for 8 years now . i dont even filter or purify the water . i figure its many times safer than the polluted crap that comes from town or the horrid rural water company .

Another option is to look at auctions for a rain collecting system. I bought one for 5.00 and I bought the price that is placed in the downspout. Total cost 30.00. Another thing is to check with you city as many have give aways
Number for says you should rinse off your roof before you collect your rain wire am I supposed to go outside and turn it on and off how do I know when it’s going to rain if I’m not home it doesn’t make sense unless you have some kind of an outfit that works let me know
It is called a First Flush Advanced Water Diverter. google it, I have not bothered with one myself though.
What effed up states prohibits collecting manna from heaven? Someone has their sticky money grubbing fingers in that, why else make it illegal? At what point will they be demanding you get a licence to breath the air?

very well said
Forbidden to collect rain water?? that makes no sense at all.
I am going to ignore that idiotic rule. Just go ahead and do it and ignore the idiot/s who tell you to stop.

Oregon. Go figgur!
It is legal to harvest rainwater in Oregon!!! You can harvest all water that runs off your roof, but you can’t build a catch basin … Please check the laws in your area …
Several states depend on the rain and snow from the Rocky Mountains for agriculture and residential water that flows into the streams and rivers, etc. Colorado has laws preventing rainwater harvesting for this reason. An example is Nebraska having water rights to the platte river watershed system. They use it to water their fields in summer, which supplies much of the world’s corn and soybean crops (among others) and much of the wildlife in the area depends on it for their life cycles and habitat. Just an example of how there is a bigger picture sometimes. It’s not always just about control and money grabbing.
