well-drilling with PTO??? anybody?

[Mustangous]

Can you use a smaller HP pump and just have more zones?

Well, I am still learning the whole irrigation system now, have lot to learn. I would assume i would need different zones, but i am having trouble finding gpm on sprinkler heads themselves to see what i need.

That info is usually available with that tiny piece of folded paper in the box with the heads. It may be available online too.

I would have to fully design the system and placement before any purchase is made. I probably have to go to a supplier, would want good quality stuff anyway.

Hi ultrarunner, I saw an artical in farm show about a guy in Texas that uses a air drill on the end of pvc pipe to drill the well. I will try to find the article and get more info tommarow, Loren

Thanks for the research and Welcome to the Forum!!!

Here is a company on E-Bay that sells plans for a PTO driven well digger. The other place mentioned earlier in east Texas is "How to drill a well.com" The fellows name is Nathaniel. He uses a circular air sander sold at HF that has been modified to fit inside of a 2" PVC pipe. His idea is very clever in theory. There are 3 holes drilled in the pvc near the head that create a vacuum from the air exhaust and carry the tailings up through a 1" pvc 100 - 150' run. Water is kept in the hole to help carry. This is a picture of the motor I built to his specs. A winged drill bit is screwed on to the threaded end. I have everything ready to go but have not tried it yet. I have an IR trailer air compressor to run it. You need a lot of air to pump the tailings up through that length of pipe. He sells everything on his site or you can just buy the plans and DVD showing how to build and drill.

1. Irrigation / Sprnkler systems need typically .8 GPM per head depending on the nozzle for the rotating heads and the " fixed fan" type use even more per head due to the low resistance and high flow of these nozzles. So "rule of thumb" is 5-6 heads max per zone of any type. This equates to roughly 6 GPM @ 40 PSI average so you need a pump that generates 8-10 GPM @ 40 PSI and a well generating 8 GPM or a deep enough reserve suppy to support the outflow.

2. Pumps in Sprinkler systms are normally set up for 30-50 PSI so depending on the depth of the well you will need a pump that generates 8 GPM at the average water depth. If you are close to the supply - a lake or consistenly high water level a "surface well" where the water level is 5-15 ' below the ground a point type or dug well will work very well.


3. Point driven wells (typically a 1.25" steel pipe driven into the ground by sledge or power hammer in 3' sections with a SST point and 3' screen section) - The end result and flow is entirely dependent on the soil type and sub surface strata - so in one area it may be sandy and the next clay, or rocky / sandy mix. Each soil type will dictate the best well "drilling" method - water evacuation with the two pipe method or brute force driving the point into the ground.

I have installed multiple point type wells in the NE and can say unless you can dig to see water (8-10') its a very tiring experience driving through rock and materials to find water with a point well in this region. On the other hand, I installed a point well 10' back from a lake edge (to provide filtration of the water) and went down 6' and had excellent quality (tested) and endless supply of drinking water from that well for more than 10 years.

So if you have lake/pond source with dense soil you can dig or create a natural filter of stone to a pump pit enabling clean filtered water naturally, or just toss the suction end of the pipe in the pond wrapped in a bag with a float to hold it off the bottom. It depends on the end use to how extensive you filter/clean the water.

To the point of using a PTO drilling rig, the only suggestion would be using a long auger to drill a pliot hole to determine the mean water level then drive a point well if water is found.

1) Look at a truck mounted drill rig.
2) Check it over, ask the driller how it works.
3) Scratch head, ponder a while.
4) Ask for a quote.
There are REASONS why they cost $600K and up.

Seriously, you will break, bend & bust stuff that co$ts more than just hiring the job.
Add the wasted time and possibility of injury and you would be STREETS AHEAD having a pro do it.
They know the permitting process for your town too.

Here is a site for a turn key system. At one point I was looking at this system.

I've talked to several commercial drillers and access is a problem... they all have large rigs and are unwilling to risk getting stuck on my back 40...

The other problem is they also get a big price around here.

I've looked at a few of the portable rigs and tried to rent one once... none of the rental yards have them anymore because they often came back damaged of broken...

I had the same issue with access and finally found a guy with a cable drill and he went 450 ft.
