The sprinkler heads are not small and cost about 750 each, I have fourteen of them. I just finished soaking/cleaning them all and I used about a gallon of vinegar hence I'm all set for six months hence when I will have to repeat. Shallow well water (under 40 feet) is notorious for containing rust and it very quickly stains walls and clogs pumps etc., that's why you see so many of those cascade filter systems where well water is allowed to filter through several trays of stones in order to remove the rust. So what were the results of the excersise, are the sprinklers now back to their best? Just like new, it takes between four and six hours to dissolve the rust followed by a quick brushing with a brass brush and voila.

Dependent on your FE mg/l, you can treat the water to stop this =3 Mg/l = phosphate treatment = 5 mg/l = ion exchange water softener = 15 mg/l = oxidising filter You can also treat with chlorine and a sand bed filter The trouble is I would have to establish an interim store for the well water so it can be treated, as things stand presently the water is pumped from about twelve metres, directly into a sprinkler backbone pipe which then feeds individual sprinkler pipes. My longer term solution is to drill a deeper well, the problem goes away after about 40 feet hence the 90 metres I have in mind will take care of the rust issue. The only problem with all of that is finding someone who will drill to that depth at a sensible price, my most recent quote came in at 1,200 a metre!

When I had the 10 acre block in Australia I was pumping out of a dam to supply my orchard with water, had small spray heads on short stands at the base of each tree. Found by keeping them above ground they were easier to spot if there was a blockage and less prone to ants getting in them.
I was in the process of devising a charcoal filter when I sold up, was going to make it in a length of two inch poly pipe that was about 2-3 metres long.
Simple a length of pipe filled with charcoal granules.
Idea was to make a couple that were interchangeable so you just removed one that needed changing out with a new one. Would be easy to find the stuff where I am now, there is a charcoal factory just around the corner.
Google "charcoal filters" they are easy to make. We are getting a new water storage tank and pump for the house soon, might make one for the house water.

All depends on where the iron and typically manganese is coming from, its from the formation and your taking water from the same formation at 90m not going to stop the problem, to be honest at usd 35/m if thats fully cased, not a bad price, we have a 93m deep borehole on the property in SA and that came in at about usd 45/m, sometimes these higher costs are justifiable on deeper wells over a 12m deep well point you have now

The easiest wat to prevent contaminents from blocking your sprinkler heads is to get a large storage tank (such as the one in SiamPolee's pictures) and fill it with Evian bottled water. No need for filters then.

I believe it was Soutpeel. But since he lives so far away from you responsibility has been delegated, in your case only, to SiamPolee who I understand is a fine upstanding chap who will be pleased to help out. And in case anyone is interested in trivia, Big C sells one gallon containers of white vinegar for 69 baht, it such a bargain I bought two! Tell you what, i will donate the case of Hoegaarden Bleth owes me, he will deliver it too you personally next time he is in CM 2 gallons of white vinegar ! What you going to do with all that ?...cant even use it for fish and chips, your as bad as Mrs S...buy bulk quantites of shit we will never use in a million years * Note to self - Don't go to cm's for dinner if fish and chips is the main course ! and Tony, this is the best way to solve the problem - i65.tinypic.com/50ciw.jpg

To be clear, my well water is solely for garden use, the only reason I would go deeper than my current 15 metres is to ensure continuity of supply, not to evade rust or for any other reason. I currently compete with the local rice farmer for the same supply during the dry season, he runs a pump overnight but runs our of diesel at about 2am each day, that gives the ground water a chance to level out and refill so I can draw from it around 6am. I also have a klong that runs through the garden so that is my primary supply (different pumps) with the well being a fall back, last year both sources dried up on me for a while hence the thinking about a deep well.
On a pay back basis my current 69 baht twice a year for vinegar to clean the sprinkler heads far outweighs the cost of a new well or a filter system for the existing well, that having been said it would be nice to get rid of the rust problem. I've read that rust is common down to 40 feet but unusual beyond that depth. I suppose if the pickup tube is located way below that level and water flows into the bore fairly evenly, the deeper well would work since rust floats rather than sinks. As things stand I'm unlikely to do much more beyond what I already have in place. I'm pushing 70 and whilst still fit, I tend to avoid projects rather than actively seek them out! All that being said I remain very grateful for the enthusiastic flow of ideas on this subject, much appreciated indeed.
