I'll be showing you how to make a three bucket filter and purifier for making almost any water safe to drink, using no to low cost materials and basic tools.
Filmed and deployed at the Rhino refugee camp in northern Uganda, where we are training South Sudanese and Congolese refugees how to build their own low tech alternative infrastructure from recycled and repurposed materials.

My name is Daniel Connell. I prototype and develop basic technologies which anyone can make using recycled materials and simple tools.
The aim is for everyone everywhere to be able to build and maintain their own infrastructure; producing their own energy, food, clean water, communications, and anything else they need.
All designs are open source and license free for any purpose, and full construction tutorials and how-tos are available on the opensourcelowtech.org website.
This water filter system is great!
1. Easy to understand the principles
2. Easy to build and cheap
3. Easy to clean and maintain
I always thought that my work as an engineer should be affordable for the masses, because technology should improve quality of life for EVERYONE. Your videos have given me something to think about.
One love from Uganda. Your projects inspire me as a young engineer
Love to hear this! 😁
I noticed something really beautiful there. Everybody was excited about the new water system, and after the mayor did the first taste, he passed the mall ground. Everybody there got to drink from the very 1st cup of water from the system.
Forget about Western ideas. That’s not what this is about.
Everybody there was able to participate in that first inaugural moment. Everybody there was important. Everybody there took a small, moderate taste and left lots for the next people.
The rest of us could learn an awful lot.
it means knowing your leader, seeing him and him seeing YOU. Our countries and governments are too big, so leaders are disconnected from the people.
A marching band parade man you went all out with the production for this video! Amazing work
Cost me a fortune.
$5?
@@OpenSourceLowTech 😂
Daniel's video literally states "How to make a $5 water filter" not 'how to purify water' and certainly not 'how to make perfect drinking water'. He said what he said and did what he did! 🤦🏾♀️ These ppl are coming for him in the comments and they haven't even shown their neighbor how to build a water filtration system. 😂 Great work Daniel, thank you and I pray you're keeping it up!!! ❤❤❤❤❤
That is very noble helping others who can help others as a result of that.
Knowledge is survival.
Keep on rolling and rocking!
You rule!
Agreed!
You Sir.. Have my respect.
I love that you help others. This alone is extremely rare. 10/10 Buddy, keep up your amazing work.
They can use copper mesh for bacteria etc cleaner
That's actually quite a good idea. I'll hopefully be testing and optimizing this design this year with a local NGO, and something like a jar full of copper wire may well increase the antimicrobial action of the filter, while being an accessible material in most parts of the world..
@@OpenSourceLowTech I am so happy that I could be helpful.
I guess I have heard that before probably a good idea but if it was not safe water before probably still needs to be boiled
Hi, thanks so much for your clear and simple explanation of how this type of filter works. Taking your idea and another for a barrel filter I have made a filter for myself to use on my off grid land. All the contents of your buckets are layered between fine mesh in a single Barrel with a tap at the bottom. Water is poured in from the top and kept topped up so the sand never dries out. Thank you so much for your inspiration. I had never made a filter before and now feel so much happier that I can. (The water will still need to be boiled for safety but I can filter rainwater I collect now).
Best video on water filtration I've seen.
At least he shows them how to make the water a little cleaner. I really appreciate your project, it still a much helps for them.
A little cleaner that's exactly how we've been making water filters for the last thousand years the giant cities where you get bottled water use that same process it's just large metal containers and then they either use UV light which is sunlight or some type of chemical either a type of bleach to sterilize it.
This guy showing them how to make water so they can go back to their villages and survive?
Why isn't this just part of all public education in the entire country
Who is them?
@@tcantrell5301 Because the system believes there should only be ~500 million people on this earth. All the governments, the UN, WEF, WHO etc. They all wish us NOT well. They say it. Openly. "You will own nothing and be happy" while you eat bugs as your diet.
Please teach this to the Living Water of the World organization. This world replace their system that need a maintenance and electricity. Thank you for all you do.
BPA free plastic buckets would be a good idea too.
How awesome sharing such easy to do remedies for water. So easy cost effective and should be Everywhere! At the minimum. Straw is also good to use in the beginning process and even along the line, to catch and filter.
Imagine a simple home unit, bamboo or likes, one piece with 3 levels.
Like a hanging garden principal.
Simple,awesome and so Neccasary!!
Namaste.
Andrea and Critters. ..XxX...
This is so cool. He is so nice for showing people how to do this! ❤️
Yep... So unlike gates and his crew who go there and poison and sterilize the people.
Great project Daniel!
Activated charcoal can be prepared if you throw red hot charcoals in water. Steam will open up the pores and will make it better absorbant.
I would still boil the water before drinking just in case.
I read that charcoal made of denser wood and in particular the nut shells is superiour to the ordinary charcoal but I'm not 100% sure about it.
In Russia you would also take 5-6 tablets of charcoal in case of minor food poisoning (hangover) and it helps.
Very interesting and good to know, thanks.
it's not really needed and also they would have to prefilter a bunch of water before doing that which is kinda a waste when regular charcoal in enough amounts with different coarse particulates will do the job fine. Boil at end is always a smart thing also.
Still not a bad idea
You could use a cloth sack such as a pillow case in the bucket to hold the sand and charcoal together. Easy clean up too.
Yeah good idea.
Beautiful people wanting to learn and a wonderful caring man to teach them. This is the true meaning of existence.
Another awesome thing you’ve done here. For those wondering...how long does the H2O need to sit in the sun for UV to sanitize it? Also, what type of charcoal & where would most people find this? Thank you...for trying to make this World a better place!
Depends, 24 hours is usually safe. Keep in mind it has to be a plastic bottle, as glass blocks most UV, and has to be filtered first or the microbes can be shadowed by particulate contamination.
There we were just using cooking charcoal produced locally, but activated is best.
You can actually make the charcoal yourself, check out Primitive Technology charcoal mound video, full instructions are in the description
Simply amazing!
Keep up with the good work.
May your tribe increase!
So inspired by you. Thank you for your work. Please keep doing what you do. 🙏🏼❤️
You are a real super hero in my eyes
This is amazing, thank you so much for doing and for sharing this!!
For your work... won my respect...
I have a little suggestion for improvement.. I must tell you..
I tried it myself...using 6 inch PVC pipe.
Made this kind of drinking water filter..
The difference is that I added an air pressure space at the bottom.
Simply put, it is to seal the water outlet.
Use transparent tube...
My experience. The speed has increased by 3 times.
My English is not good. Sorry.
Hope you can understand what I said.
Sounds interesting, not exactly sure what you mean tho.
Photos?
Made from this concept...
I try to explain...
6 inch PVC pipe: I made 6 spacer boards with feet (drilled holes).
In this way, each layer of filter material will have an air chamber.
There is no filter material at the bottom..
The lowest way to seal..
Drill a hole and use glue to connect a transparent tube.
At the beginning, the outlet pipe should be blocked first, and then the water should be filled.
After a few minutes, when the air pressure below builds up...
Then let the water flow out..
The material is 1. Cotton cloth 2. Stone. 3 Fine sand 4. Charcoal.
So the weight of the water essentially sucks itself through the filters, kind of like a siphon?
Makes sense.
@@OpenSourceLowTech Yes, you can say it again.
Do you have pictures or photographs to show us please? 🙏
Love the gracious giving that you do! The band is not bad either... (:
After filtering, the 'clean' water really needs to be boiled to kill any harmful bacteria that still maybe left in the water, then it should be 100% safe to drink
You have to be proud of yourself, respect!
You forgot to mention the charcoal removes the bad smell.
I dont know why this isnt more popular
They tweaked the algorithm last year and now I get pretty much no views, basically.

no one teaching birth control or population control will ever get an award or much praise, but that person will save many more lives, I'd bet. Africa has 7 kids per couple on average. For a poor couple, even one child can be a financial burden.
@@genkiferal7178 Jesus christ. In a world of abundance purposely made scarce to serve the "elites". We don't need population control Mr eugenicist. The world is not overpopulated. CO2 is PLANT FOOD. More = better. Will not do much of anything with the temperature. Which is steadily getting colder as we approach the grand solar minimum. You still go around believing the likes of Bill Gates? Listen to Klaus Schwab and Yuval Noah Harrari at the WEF and see their plans for you. You useless person who should own nothing be happy and eat bugs. While they murder the entire earth by blocking the sun, poisoning the water, sparying the skies and taking away CO2 and all other essentials for photosynthesis. All "climate scientists" on TV and ONLY the ones on TV agree. Photosynthesis no longer exists. Plant food will kill the earth. SEVEN year old children know better!
@@genkiferal7178 Wow. Do you work for Bill Gates and the WEF? Do you want 500 million people or less on this earth? Jesus christ. Turn off your TV dude. It's melting your brain. You might soon think if we delete CO2, aka. plant food completely then all the plants die and somehow that will lead to us "saving the earth"! Don't forget blocking out the sun. Maybe control water. Can we poison the soil as well? Just so we delete 4 out 4 essential things for there to even BE an earth or ANY life on it. You are ruled by psychopaths who want to destroy us all. And you worship their every claim! It's sad even now, almost 3 years into the greatest hoax of all time, there are people as brainwashed as you. It's very sad!
I'm gonna build one of these in the corner of my basement suite. Set it up to make me four letters of perfectly clean water to drink per day. ❤️
I'm going to be making one of these from some old galvanized metal buckets and scrap wood.
Fascinating. I so appreciate this
I hope you can make a video (or share a link) of the proper way of how to make the charcoal/carbon that can be used in the filter instead of buying them.
Thank you. That's really valuable.
8:40 “So this is the United Nations water”
That tells you a few things about the United Nations.
Thank you texas hat man thank you im gonna build one at home thanks again my brother
There are gold classifieds that have very fine mesh screens can fit into 5 gal buckets
Gold classifier screens that will fit into 5 gal buckets
Interesting.. what are they usually used for?
Same available in silver?
The very top filter I use is made out of cheese cloth and a very thin drape material to catch dust sand and leaves. Then my layers of charcoal and gravel.
The cloth filter is just rinsed in boiling water as maintenance
Interesting. How's it working overall?
What kind of setting are you using it in?
@@OpenSourceLowTech it's working good. It is very primitive and dirt cheap but it works. The water is clean to drink. I use old filters from the store to do an extra filter sometimes. On the gutter I made a cup filter filled with charcoal to catch dirt . Set up is pretty primitive due to lack of funds.
I don't know what you mean by setting
Sounds good. What part of the world are you in? It's rain water?
@@OpenSourceLowTech east Europe Bulgaria. Fog rain snow. I am making a fog catcher as well. You can never have enough drinking water
Be worth documenting that..
Doing good for other people is Good
Amazing work Daniel (is it?)! How have you come to do this work? And are you still helping or working there?
What a wonderful blessing you are. 🙏
Great video. Dead on.
Next water purification system, solar water desalination distiller for salt water to fresh water

that thing would be cool if it had a solar panel and a electric water pump
Great video.
Americans can sometimes get food grade buckets like this at large bakeries and often free - especially after major holidays such as Valentine's Day or Mother's Day.
Good to know, thanks.
I think I saw this in a survival book too... SAS Survival Guide perhaps.
Has anyone ever checked these out with a dissolved solids meter..? Wondering what the ppm is of the "clean" water.
An FYI, always run a few gallons through to get rid of loose material, then it should be good to go.
You can clean each component before it is assembled
PPM is only half the story. You can filter water to 11 ppm but them put a few drops of cryptosporidium in it and it would still register 11 ppm.
About time someone showed them how to filter water 💦 💧 especially with this charcoal method, good on you dude👍😃
Yep.. mine was glueing itself together
Give a man to clean water and he's watered for a day. Teach a man to filter and he's watered for a lifetime
then he can overpopulate his area and make war with the neighbors to overpopulate _their_ area.
@@genkiferal7178If you research earth's population sustainability you'd realize overpopulation is not a dire issue. Plus the fact that you haven't ended your life in order to lower humanity's numbers proves that in your heart of hearts, you aren't even genuinely concerned.
@@Trentsum so we can send all of the illegal immigrants (who cannot live in the areas they were born in for SOME reason) to YOUR area? Great! And, YOU can pay for them - not other tax payers. And YOU can clean up after them - not your neighbors.
@@genkiferal7178 No. In reality, the government will send them to your area and use your money to give them welfare, and all you'll do about it is continue to pay your taxes and squawk about it to strangers on the internet.
@@Trentsum What a clever reply! Well done.

carbon is like a magnet capturing the steel of the water... the steel - is bad things. Cheers!
Great video 😎👍
Awesome 👍
Have you used or considered a final stage container with scraps of copper (or silver) wire to purify in lieu of boiling?
💖💖💖💖
Thanks
This is cool,it's how are home filters work in the US they have charcoal in them
Yeah mostly.
Interesting. Have you surveyed the impact on under-fives' incidence of diarrhea? I've got simple, internationally used survey questions and sampling processes if you want them.
THANK YOU SO MUCH I LOVE THESE PEOPLE YOU HELPED SO BEAUTIFUL A PEOPLE THE MALE'S AND FEMALES. PERHAPS THE PEOPLE CAN LEARN TO MAKE THEIR OWN CHARCOAL FROM COCONUT OR WOOD . HOW LONG IS THE SYSTEM GOOD FOR? DOES ANYTHING NEED REPLACING? THANK YOU SO MUCH KEEP UP GOD'S WORK.
All the charcoal we were using was locally produced, for cooking.
Next steps are field testing, to see how often the mediums have to be cleaned or replaced.
They say hard woods and coconut coir work best
Good job but biosand filter is better, there is some gap in your buckets, the water is just clean from dirt but not from others microscopics bacteries and viruses, maybe putify with UV, put water on some bottles on sun light 24h.
The middle bucket should develop a biofilm in a couple weeks of use.
I'm looking into sunlight based processes.
@@OpenSourceLowTech I think the second bucket should be longer because the sand has a role to not let oxygen inside that kill bacteries and pathogen, to be efficient buckets need to be filled with water 24/7.
The problem with the sun light it take time to purify water, but with uv-c blub that can be run with dynamo like led lamp you can speed up the process, look at how it is.

Excellent! Factual, relevant and concise! It may be overkill, but what about activating the charcoal by soaking it in citric acid? Thanks.
I looked at options for doing that, but even tho there were several which were fairly low tech, they were all a bit more energy and or chemically involved than I'm really happy having people have to do.
Have been looking at other options to the char, like iron oxide, which may work better and be a bit easier to source and work with.
@@OpenSourceLowTech Thanks.
Surely the fine charcoal water is good for the soil?
It would be, yes. After Rhino Camp I visited a permacultural project in Kenya called OTEPIC, who are doing starting to experiment with Terra Pretta.
How often should you change the gravel, sand, and charcoal
Really depends on usage and specifics.
I'll hopefully be doing more testing on this design, and a variant using iron oxide instead of carbon, some time this year.
The best way to teach,is to have them do it,just saying how you did it some things will get lost
Indeed, we all of us made several more filters after this.
@@OpenSourceLowTech cool,I worked in a factory for years,running big printing presses,one day I had to train this older women on the press I ran,she looked full of fear,so I said,I'll going to break each step down to show you it's easy,you will do it and I'll just point to what you need to do,3 days later,she was running the press and said,your right Joe it is easy,I'm dyslexic so growing up learning to read was so hard,it took years even in highschool I was still fighting to learn to read,I learned alot from it tho,
Great videos man,I love the water turbine,
How often those sands, gravel, and charcoal to be replaced or changed?
When water are in, those buckets wont become to have stuff like molds?
Good man. What else is there to say.
Very interesting and commendable on your part. question, how long do you use the system until you change the filters?
As long as the water keeps flowing it’s usually a self cleaning system
Sand and gravel never have to wash over in years to come after that? How bout charcoal?
1. mechanical cleaning of water - check. 2. chemical cleaning of water - check. 3. biological cleaning of water - boiling. Then you are absolutely sure it won't harm you.
Boiling is effective, but takes quite a bit of energy, and then needs to be left in a heat proof vessel for some hours til it cools down.
This is awesome! How often should you change the charcoal?
Whats the gravel for? You can change it for sawdust or moss or something similar after the sand bucket would make a better filter than the gravel, that would only be needed to filter out rough debree.
Sawdust would rot, moss could be an interesting idea but gravel is what we had lying around, is inert, and about the right size for taking out the coarser stuff.
@@OpenSourceLowTech in Russia moss is often used during ww2 as binding material for wounds because its sterile, maybe fill one bucket with some kind of water plants with the roots etc intact these are good purifiers in aquaponics systems as well, than instead of gravel I'd suggest volcanic rock or similar if available its a better filter than plain gravel, but I understand you when you say with what we had. How did these peoples ancestors used to live before the missionaries came to their lands? go back to the roots more healthy and sustainable lifestyle usually
How about mixing the pebbles,sand and charcoal??
one was taking a photo with an iphone!
2nd hand price of my iphone is £30 tbf
They were filming with one of us volunteers' phones.
Are they food grade buckets? Do you need to flush once or twice before drinking the water? Well done to you? 👍😉🇮🇪🍀
Thank you for sharing this. Would anyone know where to get plans on how to build large systems like this?
How large?
@@OpenSourceLowTech I can conjure up something for that.
Bless you Daniel. I am an old woman in the US and was looking for a diy way to filter and reuse shower water that has soap in it. I nearly fell over seeing you filmed this at Rhino camp. I have a young friend who lives at Rhino camp and he reached out to me to help him with his writing. I met him through my refugee son in Kampala who became my son long distance as a result of a writing assignment. Both young men hold humanitarian positions to help refugees. I just write about them and have become their second mom. Small beautiful world. Do you have the specifics of the size screens for the various particulates? I plan to run it through my Berkey filter at the end of your process. Any thoughts on soap removal? Bless you Bless you Bless you.
Thanks. Who do you know there?
The screens were just what we could get which seemed to work, it shouldn't be so sensitive that you need to break out the callipers, just eyeball it.
Detergents and the like can be tricky to filter, I'd probably look at bioremediation, ie a reed bed or the like, if that's an option.
@@OpenSourceLowTech I sent you an email with my contacts in Africa
Doesn't seem to have arrived..
is there a technic helping to remove fluoride and chlorine from drinking water?
chlorine evaporates if sat on your kitchen counter overnight. I often do this when I need to make bread. I don't want the chlorine killing the yeast in the bread.
I made one to keep in case of emergency.
Nice. How'd you find the process and results?
@@OpenSourceLowTech I haven't used it yet. I bought almost everything at my hardware store and used cheesecloth as well as a screen. The Charcoal I had to order online. It was a bit more expensive here in the states.
The bottom bucket has a spigot and I keep it all unassembled. Each bucket sealed to protect from dust.
Preparing for the big one here in California.
Ok, makes sense. Keep in mind that these types of filters generally perform better after a couple of days to weeks of use, as the sand will in that time develop a biofilm layer which digests microbes, and the charcoal will further activate as the pores flush out a bit.
But if it's going to be potentially years without being used or cleaned then it may make more sense to store it dry as you have it. I'm not actually sure...
@@OpenSourceLowTech great thank you for the tip.
does ths need to be cleaned or replaced eventually?
how much water can be filtered through these amounts of material?
I was getting about eight liters per hour.
How often do you have to change the bucket contents?
He says it at 12:00 in the video.
@8:40 - What possible reason is there for the UN to be giving out actual DIRTY water to human beings for drinking? Why? WHY???
no charcoal? i doubt a bit
my question is: will this filter heavy metals like lead?
How effective is this against biological contaminants?
Is that a New Zealand lower south island accent I hear?....
Largely grew up near Christchurch.
@@OpenSourceLowTech Cool. We thought so. We heard the NZ accent then the slight roll of the "R's" was the give away. We picked Gore or Invercargill. Our boys just went shark diving down there a couple of weeks back. Good to see another "Kiwi" making a difference in the world.
Show them to boil the water. Filtered is not purified. You still have to boil the parasites out
They know, but it's a lot of time and firewood, and they don't really have large enough cooking vessels to do much at a time.
@@OpenSourceLowTech sounds like we'll have to come up with s few ideas on how to get the water purified.
I want to experiment with iron oxide instead of the carbon, which when in sunlight apparently has fairly broad antimicrobial effects. And would just be some steel pot scrubbers in a clear plastic bottle..
Is the charcoal anti-bacterial?
Kind of. It's not antimicrobial in the sense that it kills stuff, but it will pull bacteria and to a limited extent viruses out of the water. But if you don't then keep it clean via backwashing or other sterilisation then it can become a bit of a breeding ground..
Thank you Daniel for the great info!
Perhaps following the char with another bucket of fine gravel would do a better job of breaking up the water molecules into smaller lumps, like a stream bed does? Making wetter water.
what country is it?
Uganda. Rhino refugee camp near Arua in the north.
What is “Granite water filter” shown by BBC ?
Does it filter out e-coli?
The sand is the "ceramic" filter, I think.
In municipal water filtration plants in the US, the top layer of the filtration media is coal (Anthracite or GAC) followed by sand followed by gravel. Is there a reason your filter is opposite? Does it perform better under the local circumstances?
Essentially with this design I just replicated known approaches. Given that the water these guys have access to can be a bit... chunky... I figured the gravel first would be good to take out the larger particulates, and is easier to wash regularly than the char.
But I've also seen configurations like you describe, I'll keep it in mind as an optimisation, especially as it would be trivially easy to change the order of buckets.
Water that is dirty needs to have the large particles removed before charcoal. Otherwise it loads up the charcoal prematurely. Charcoal on the bottom will last longer and produce better tasting water.
@@1980Baldeagle correct
@@1980Baldeagle why not screen out the larger particles first? many will float so a screen within the bucket might work.
The purified water is safe to drink?
