bannork Posted May 8, 2020 Share Posted May 8, 2020 Greetings fellow farmers and gardeners. The situation is this. I have 4 strips of land approx 300 metres long each, the width of each is 4 metres. I intend to plant bananas down the strips, flanked by various trees, plants and herbs. I want to water these with mini sprinklers approx 1 metre above the ground. To power these, I'm building a water tower at the top of the field. This will be 5 or 6 metres in height and supplied by a submersible pump in the bore well. Assuming I only open the valve on one strip of land at a time, does anyone know if gravity could power approx 75 mini sprinklers ( assuming 1 every 4 metres)?! Thanking any informed posters in advance. Link to comment Share on other sites More sharing options...
Popular Post In the jungle Posted May 8, 2020 Popular Post Share Posted May 8, 2020 The short answer to your question is no it will not work. Here is a website that will enable you to work out what is required: https://www.irrigationtutorials.com/ A water tower 5 to 6 metres gives only 0.5 to 0.6 bar of pressure before losses in the system. My finger in the breeze estimate is that you need a 2hp centrifugal pump at the base of the tower, 2" pipework and break up the area into zones using valves to water one zone at a time. Better if you do the research and calcs though. Personally I wouldn't bother with a water tower at all. Cheaper, safer and easier to maintain the system using water storage at ground level. 9 1 Link to comment Share on other sites More sharing options...
Popular Post Tagged Posted May 8, 2020 Popular Post Share Posted May 8, 2020 Have you trought about drip watering system? I do that now and gravity feed works perfect for less than one bar pressure. My thanks os from 30 cm to 6 meter elevated from top to bottom. 6 Link to comment Share on other sites More sharing options...
talahtnut Posted May 8, 2020 Share Posted May 8, 2020 I've made a similar system from a well on a hill which gives me 1 bar but I can only use drippers which I leave on, unless its raining. You might consider large bore delivery to the drippers. 1 Link to comment Share on other sites More sharing options...
jvs Posted May 9, 2020 Share Posted May 9, 2020 Why not use the pump to pump water to the tower to pump to the trees straight away? I think a tower is very old fashioned and imo a few solar panels and a dc pump will do the job for you. You could also dig a trench in the middle of your land strips and pump water in there,will save a lot of piping and much easier to work with.Need pretty level land for this to work. Al depends of course how far along your tower is already,i would guess building a tower like that can be a lot of work and cost a lot. No need to store water if you have a good well.

Popular Post Grafting Ken Posted May 9, 2020 Popular Post Share Posted May 9, 2020 Drip is a good way to go without a pump, I make these rings up myself from micro drip line and can irrigate 80 plus trees at a time just from the tap. 4 1 Link to comment Share on other sites More sharing options...
Grafting Ken Posted May 9, 2020 Share Posted May 9, 2020 From your tower you should be able to use 40 or so of these little fellas at a time with no pump. 1 Link to comment Share on other sites More sharing options...
Grumpy John Posted May 16, 2020 Share Posted May 16, 2020 In the jungle summed it up pretty well. It's not as straight forward as you may think. There are charts to refer to for reliable information as to pipe diameter, pressure drop, friction losses. Do some research. Link to comment Share on other sites More sharing options...

Speedo1968 Posted May 17, 2020 Share Posted May 17, 2020 What a wonderful selection of information, thank you to all who have replied. ( Involved in farming since the early 60's, UK and other countries including desert areas. Unfortunately now retired ). Good luck to the OP, I am sure you will get it sorted.

Fill those HDPE caged tanks up with some H2O and let it run for 24 hours, then see what you got . Looks good to me ✌️???? Link to comment Share on other sites More sharing options...

IsaanAussie Posted May 18, 2020 Share Posted May 18, 2020 Thanks for posting the details. Too rich for me. Looks like I will be making my own. My ATV is only 150cc and I was quoted 15K for a trailer to suit. I want to use it as a boom spray as well as a mobile solar panel and other equipment unit. 1 Link to comment Share on other sites More sharing options...

IsaanAussie Posted May 18, 2020 Share Posted May 18, 2020 This is the one I was quoted 15K for. Second picture is our little ATV. First I need to find a tank for the spray system. ATV rated to tow 300 kg, so ideally about 250 litre tank. 2 Link to comment Share on other sites More sharing options...

Great tool for fam theese atv’s Especially when no roads to access the land except small bumpy trials. Link to comment Share on other sites More sharing options...

I would prefer to get a flat tank to get the CofG down as low as possible. I have seen them here, they are usually just rotary moulded with a high percentage of reground plastic and not that expensive. God, I am getting old! They probably 3D print the damn things to exactly what you want these days......... 1 Link to comment Share on other sites More sharing options...

That was a good idea, I only had my eye for the ibc containers around here, but there is loads of used plastic tanks everywhere you go, so shouldnt be hard to find something proper.

IsaanAussie Posted May 18, 2020 Share Posted May 18, 2020 (edited) Just now, Tagged said: I only had my eye for the ibc containers Probably what I will use. Have the ability to overload if the conditions allow and to gauge volume ratios, maybe more importantly they have larger size drains etc.. and they come with their own "roll cage".
