A major advance in gravity-feed irrigation (see also Unpowered Terracotta Valve)

Three questions are answered. (1) Is there a low-cost, accurate and uniform method to water your garden from a rainwater tank?
(2) Why is this information not available from any irrigation supplier?
(3) How can the irrigation system be automated using a solar panel?

Intuitive and organic strategy. I appreciate the solutions and simple, scale-able technique. Very helpful.

[@thymekiller]

very clever. some great ideas here. love the evap level control

[@multicolouredhuman]

Super tutorial, thankyou for the clarity of instructions and for dispelling the irrigation pump myth👍

[@danielmcardle3476]

Thank Dr. you Bernie. That is one great and extremely helpful video. I will use your ideas to the letter. Well, as far as possible - I am sire something will be different!

[@Rudimentary007]

Never new this. Thank you.👍🙏🏼🇺🇸

[@unclebodieshomestead3972]

Thank you for this video. I’m new to homesteading and have been looking for this answer.

[@John.Doe-OG]

I hope you keep making Videos Dr Omodei. I just sub'd and I will watching you older videos, too. Hopefully they can help me get over one of my design issues. I'm planning on doing it without a pump, so stumping the flow to my reservoir when it fills is my current hold up.

Brilliant idea and execution...

[@ToneTruong]

That's a great idea with the vinyl tubing to check water pressure down the line.

[@metubelv]

Excellent work!

[@infestedkudzu]

This is slick. nicely done.

[@jungsomewhat]

very very good thank you..

[@CredibleHulk10]

This is amazing.

[@sullivanjoef]

Great! Thanks!

[@binhminh417]

Thank you!

[@MrVictorchase]

Excellent guide. What would you say is the practical limit for area that could be irrigated by this method? Might it manage say a half-acre or more? Is there a real limit?

[@nrulona5276]

Won’t the green evaporator box with water be good breeding ground for mosquitoes? How do you control them?

[@sionefonua8138]

Thank you Bernie!! Great stuff. Can you tell me where I can get the coloured nozzles from. Thank you again.

[@DrBernieOmodei]

The nozzles are available from Howard Electronics in the USA

[@lotsofsparks32]

Ebay assorted dispensing tips

[@robertwoodruff8491]

I bought some needles. But can't find the connectors to connect the needles to the tubing. The stuff from rainbird doesn't fit in the needles. Where can i get the connectors?

[@anthkraus4433]

I need to irrigate my hop bines

[@atwellncube6998]

Thax so much for the information . I would like to ask if gravity can be used for sprinkler irrigation ? If yes can u please help me on how many meters can it be raised from the ground

[@DrBernieOmodei]

You will need to use special gravity feed sprinklers. I am aware of two such products, the Wobble Tee Sprinkler and the Lo-Flo Sprinkler.

[@kimemery1188]

Hello Dr Omodei we are building a garden that is about 100 " in length and would like to use drip irrigation supplied from a rain barrel. Will your system work for a garden that is of this size? with a garden that is 100" in length do I need to have the rain water tank elevated to ensure water pressure?

[@DrBernieOmodei]

For a garden of this length it is advisable to elevate the tank. To reduce frictional head loss you my wish to use 1 inch poly pipe.

[@bonitabromeliads]

open water evaporates at a different rate then water in soil

[@bernieomodei1444]

Hi Matthew. A control dripper is adjusted so that the plants get the desired irrigation.

[@orvwilliamschen2647]

Where do you buy short plug stainless steel needles?

[@bernieomodei1444]

You can buy dispensing needles online. Just Google "dispensing needles"

[@orvwilliamschen2647]

Thank you soon much for your reply. Knowing the correct search words.

[@samsonbonita5960]

Hello Dr. Omodie,i have a 1 hectare farm. I would like to know what height should i put my reservoir. And the tube size going to trees. Hope to hear from you. Thanks...

[@daniellehorton822]

water seeks it's own level and it seeks the shape of it's container come on people don't you get it we do not need pumps we need pipelines and a high source why are these people so ignorant

[@DrBernieOmodei]

The companies selling pumps and pressurised irrigation supplies have a vested interest in keeping people ignorant in relation to gravity feed irrigation. Did you know the Netafim does not sell gravity feed irrigation systems in Australia. However they do sell gravity feed systems in Kenya where farmers cannot afford pressurised irrigation.

[@bernieomodei1444]

Hi Luc. My more recent videos and the Measured Irrigation website have a lot or recent developments for irrigating from a rainwater tank.
