How Gravity Irrigation Works 

🎯 Key Takeaways for quick navigation: 00:00 Water *moves by gravity without electricity, governed by physics.* 00:39 Water *pressure is 1 psi for every 2.5 ft of head. In metric, 1 meter equals 1/10th of one bar.* 01:06 In *flat landscapes, flood or furrow irrigation can use low-pressure gravity.* 01:35 For *pipes and irrigation systems, height above the point of use determines pressure.* 02:02 Drip *irrigation needs a minimum of 10 psi, requiring water storage at least 25 ft above.* 02:55 Sprinkler *systems require at least 30 psi, needing water storage 75 ft above the outlets.* 03:36 Check *product specs for minimum and maximum pressures; consider elevation and friction loss.* 04:04 Friction *loss in pipes affects pressure at the outlet; use charts to determine friction loss.* 04:59 Float *valves maintain a steady water level in troughs or tanks, ensuring a constant water supply.* 06:07 Siphons *use gravity to move water over obstacles without the need for fuel or electricity.* 07:04 In *rainwater harvesting, a "wet system" allows water to flow down, up, and into a tank.* 07:31 Gravity *irrigation principles can transform landscapes sustainably without the need for external power.* Made with HARPA AI

honestly this channel is fascinating

No one teaches permaculture better than Andrew. Just bought a 36 acre farm in Western Colorado, I got elevation, multiple springs.

Year's ago I learned to flood irrigate in Western Colorado. Standing in a field of grass while using nothing but a 00 shovel I found peace. I still have that shovel. The hardest lesson to learn seemed pretty simple. Water flows downhill.

I truly believe Your channel is the most important channel on youtube this will be studied for centuries as the knowledge on your videos is absolutely timeless

I wish I had seen this video six months ago before renovating my landscape. I feel fortunate to have learned enough from your previous videos (and the work of others) to make sure my first renovation was successful. You are providing the 2024 Spring to-do list! Thank you for your efforts. Your work is greatly appreciated

That water pipe going up to the container is such a simple fix. I thought there was only one place where I could collect rain water off my house, but this opens up a lot more possibilities.

I used this channel to write a book and a project to submit help our nation. This guys input was amazing. I can now clearly give info on permaculture farming and water usage and harvesting

Has to be one of the best permaculture RU-vid channels I've found

Thank you for this channel! Just watched MrBeasts new video "I Built 100 Wells In Africa" with over 117 million views after 2 weeks. If MrBeasts team knew Permaculture as well or would know your new online course, we might have Kaizen, as seen in India with the Paani Foundation.

This education is priceless! Thank you Andrew!

This is the 2nd time I got fascinated again with RU-vid's content. The first one is Kurzgesagt.

Great primer Andrew! Always excited to see your new videos come out.

I didn't know about the wet system, thanks for sharing all this information!

Thank you Andrew for the excellent video

Thank you sooooo much!!! I've been looking for a visual on this info. Reading it just left me with so many questions. You made it make sense!!! My garden thanks you as well!

Good work Andrew!

Oh oh this solved a big problem for me! ❤ Thx!

This was an excellent explanation, thank you

You are a true hero of our world. Thanks for sharing all your knowhow. Even sitting at home we can study.

Interesting and helpful to know. Thank you!

This is what I needed to get me back on track on a current site; I really appreciate your work it is amazing thank you. I would love to work with some future projects, I have some really great ideas that complement your expertise.

You reminded me of my fluid mechanics class. Good news, someone else did the math - here are the tables! :DD

Thank you for increasing awareness to these methods. It would do well for parks and forest services as well as farmers, ranchers, and townies to adopt rainwater harvesting methods using (primarily) onsite materials. The West and Midwest, as well as internationally critical areas need these methods. This is important to build resiliency for now and in the future.

Great video, as always. Greetings from Costa Rica.

Another impressive video !!!

thank you!

The coolest video on youtube!

Thankyou for this, your channel is amazing

I learned so much in my PDC pro class and was so excited to receive my certificate signed by Andrew himself. Its the most inspiring knowledge and I continue to grow and imagine solutions to permaculture problems with this invaluable knowledge gained. Andrew you are an angel in this world, one day I hope to meet you and work with you. Absolutely brilliant.

Andrew, your knowledge is truly amazing and valuable! If I will have a piece of land in the future I will for sure use the wisdom you provide with your channel and hopefully be able to do a course with you or work with you! I would love to design a water plan with you for land I might become an earth keeper for. Thank you so much for your effort to specialize yourself on this very important topic to keep or restore both nature and humanity in a vital flow of life.

My favorita channel

Wow these videos never disappoint! Amazing work once again: not only are they so informational and well made but they also put me in such a good mood because they give concrete ways to take action in the face of climate change and subsequent newly arising hardships: I really believe that if we want to get some change going we have to feel empowered and the rhetoric surrounding climate change cannot just be "do less of something" because as humans we are not very good at that; but in your videos the rhetoric becomes more of a "there are these following things we can do better than in the past: let's construct in this more efficient way, let's do that in this better way" which is a type of message that is very motivating and positive and that as humans we respond very well to :) Also this video is very empowering because it gives people the ability to do some back-of-the-envelope calculations even if they are not engineers or have some similar degree: quantifying something really helps in not building things that won't work anyway and this way it becomes easier for someone to quantify even a small diy project.

Thank u ❤

Love it !

Ok you just got me as your subscriber

Nice Video

شكرا لك

Thanks Andrew for another informative video.

Damn you know the drawing Very nice

Love your drawings! And very good info! Thank you!

Wow. Such a brilliant explanation .. you should become a lecturer in permaculture and water systems ..😂😂😂. But seriously I love your channel and I devour your content its so good…😊thanks

You are a vault of really useful info Andrew 🙂

We're just getting into permaculture. Unfortunately we live on flat plains. I'm not sure what to do to build up our water store

You don't need 10 PSI for drip irrigation. Flag emitters can work even with less than 1 psi. I know, I have been using flag drip emitters with an IBC rain tank raised up on cinder blocks through 3/4 inch hose and 1/2 inch drip lines 50 to 100 feet long. Depending on the water level in the tank and ignoring friction my pressure would be roughly between .7 and 2.3 psi, averaging around 1.5 psi. You have to let the drip run longer than if it were at 10 psi, but that's not really a problem.

Very cool video, I've been looking into irrigation for more remote areas. Have you ever come across using capillary action to elevate water?

You're so cool, man.

Interesting presentation. I have worked in some local irrigation projects, the hydraulic calculations are very interesting, for system to work. Last year I have designet a siphon, too.. I am in love with hydraulics. :) For fire hydrants, calculating pressure, we start with first important pressure> we call it `the service pressure`. Thanks for all videos! Respect!

Been researching how to make your key line strategies work in Reno, NV to grow a permaculture food forest🤔

I love your channel

❤

You need to clear stagnant water in wet tank system.

Hi Andrew, thanks so much for sharing your wonderful knowledge and more! I’m wondering if you can offer some advice (or recommend another channel) on ways to better harvest and manage water on a smaller scale …. Say 1/2 an acre or less? Many Thanks 😊 🙏

What is the biggest syphon irrigation system in the world? Does it really work for >Hectares of agriland?

i love these videos. i love water.

Wells are obviously a luxury, but the easiest way to bring water to the individual is through rainwater harvesting. When my family goes camping we use a julka ran in solar and batteries for our pressure. I run stream and pond water through a Sawyer water filter for drinking water. It's cheap and simple. Wells are expensive and deplete the ground water if water storing techniques are not being used.

I took the PDC during the pandemic; what is different between it and PDC PRO?

Hi I’m new to the channel great work . Would you use a filter if it’s is pond gravity fed?

💟

Exelent vid .ive been an irrigation tech for 25+ yrs.yes yes yes😂😂😂.no wi fi. ⚡️

Do you just write backwards? I really want this setup for my training seminars and videos! Love your work!

Good morning! What do you know about using hirdraulic ram?

ThankQ

How do you manage mosquitoes in the swale? Also what about managing for insects and rodents? Would services like Orkin cause problems with the agriculture part? Also, managing high pollen and allergens?

Question on the pond, how do you keep the spot where the pipe goes under ground from being a point that erodes the dam?

I feel that if you, Tyler Ley, and me got together we could do some great things for the world...

Bro how do you write backwards

You are a legend 👍✌️👏👌☝️

Thank

My 90 acres are almost completely flat, hard to move water that way :(

Bilgilendirme için teşekkürler efendim RU-vid kanalımdan selamlar 6:36

❤❤❤

I know it's a stupid question, but how do you teach this class? In this case, are you writing on a transparent board with a light pen? Can someone explain it to me? I work at a college and I want to make recordings like this

There are no wizards but engineers 😭

You need to visit Mesopotamia modern day Iraq there is such a good opportunity to turn this semi desert land back to what used to be one of the greenest land of the world

I try to understand coz I can't speak English 😢😢😢

My 2 Yr old brother knew all this so he tried to hit me with some guava😅

I should call my ex-girlfriend......

Thank you! This is awesome! I just posted a video 4 days ago gravity irrigating out of my duck pond to swale!

❤
