The clarity of the water is due to the depth from which it is drawn. There is no organic activity down there and no "spare" oxigen. Just to put your mind at rest, the metals which get attacked most voraciously are the soft metals like copper, aluminium and, of course, brass. I did my own solar hot water heat exchanger which works brilliantly but, being made from copper, soon developed some pinhole leaks and as for the electric immersion heater, I'll Say no more. all is well now. Soft water is king. Your deep well pump should be entirely stainless steel. the shaft and electrical connections will be segregated from the water by some extremely strong neoprene rubber gaskets so there should be no problem for the pump.

3.6 kW of solar doesn't sound very portable to me.

I agree about testing. This is the first step in deciding what equipment will be required to produce minimal mineral water. When I had my borehole drilled (51 metres) my water test showed loads of calcium carbonate in amongst others. This was due to gypsum rock deep underground. The water was so hard that no amount of resin would fix it. Many metal water fittings including the jet pump venturi, which completely disintegrated, were affected. I stopped using the borehole water pretty quick and went exclusively with a 5.5 meter surface water well. Filters are zeolite, carbon and resin. The zeolite is good for many things including ion exchange which deals with heavy metals and softens water but also it's millions of tiny pores are very good at capturing suspended particles in the water. Then there is a carbon filter which collects more of the same but not quite so well then on to the resin filter which may seem redundant but, unlike the zeolite it should never need replacement. This is due to a rejuvenative saline cycle. The best people to see about water treatment in Buriram are a company called PP Water. They have a website.

There must be something wrong with a country where fear of theft stops one from dressing how one pleases. Granted there are known hotspots where this behaviour is more likely, so where is the fear of repercussion? Where are the law enforcement agencies? Answers on a postage stamp which I'm sure will be big enough.

Yeah. The problem was probably the huge cost of building a kettle big enough for the amount of water and the crane to handle it.

A better solar kettle without electricery. And it works too

Comes complete with diecast aluminium box and timer.............😊

Here's my modern Solar kettle. It screams like a demented old village woman when it's ready to release water. https://media.karousell.com/media/photos/products/2024/10/28/kettle_1730099503_c1a4b0bc_progressive.jpg

Now. Now. Be nice. He's got his Rolls Royce of kettles and probably very proud of it.

Reference over-paneling. The only consideration is to remain within the parameters of the inverter/charge controllers. There is a limit on the maximum voltage and power they can take. For example: My panels are arranged as 2 per string, and three stings per group with a massive total of two groups. Each string is rated to give a maximum voltage of 100.45Voc and a maximum current of 13.15A Imp. This will give a maximum power of 100.45V x 13.15A = 1.32kW With three strings in parallel the maximum power would be 3 x 1.32kW = 3.36kW. The SRNE charge controllers I had been using prior to upgrading the panels were rated below this maximum power figure. Even with panel derating the SRNE's were cutting it a bit fine and they let me know in no uncertain terms they were not happy. I replaced the two charge controllers with a couple of PowMr 80Amp units with an input power rating of 3.84kW and voltage rating of 160V. Now everybody's happy again.

Where I am, agricultural land prices are in the region of 300 - 350k per rai. Village land for housing can be treble that. Well positioned land for commercial use can be over 1M baht for half a rai. There are a few rubber plantations not too far from me so I would guess their value would be about the same. Note about the soil quality. Any trees that have been growing for 15 years will make for usefully healthy soil.

In a slightly related incident, I recently renewed my marriage extension in Buriram immigration office. For the past couple of years, there has been no requirement for a Kor Ror 2 to be presented. That is now required and not only that but it needs to be witnessed and signed by someone who knows you are still happily married. If you are in a village 25km from the immigration office and unaware of this, then you will have a bit of legwork to do.

There is very little difference between constant pressure and what you have. Your system has a bladder tank utop which sits the pump. The pump pushes water into this bladder tank until the trapped air pressure increases enough to switch off the pump via a pressure switch. As the water is used this air pressure decreases until the pressure switch is activated and the pump starts again. It is the air pressure in the bladder tank which gives you the relatively constant pressure at your faucet. The pump will automatically try to maintain this pressure by cycling on and off. If you already know this then ignore what I have written.

Agree with Carlyai. I also have one of these pumps which is still going strong and trouble free after ten years use. My pump power is 350 Watts but, unlike yours, it lives in the shade in its own purpose built shed. Keeping the sun off it is good.
