  1. like i said, the israelis made that same stupid mistake; the the israeli forestry people planted tons and tons of jerusalem pine and eucyllyptus.... nothing else can grow....

    now the policy is a variegated planting of several native species, etc.... but just tree planting is not effective...

    proper water management conservation and farming techniques are better short term plans for the near future

    plachon waiting for links.... thanx

    I find Andrews ideas very positive.

    I found a forestry research center in Yasothon, Isaan. They give free seedlings of various tree species to people interested in tree planting. According to them there are many such research centers all over Thailand with free supply of seedlings but no interest shown because no fun related to it.

    I can fully understand this because tree planting is work and no fun. Working should be fun. Some adaption to local customs needed.

  2. I've been to all of them.

    Roi Et was without a doubt the nicest.

    Agree, the locals call it the smiling city :o of Isaan. The government invested some money 20 years ago, built a nice lake in the middle of the city with a beautiful park. Yo can also find more nice well cared restaurants with varities of food than in most of the Isaan cities. Gardening shops are opening around the city. A nice relaxing place, not to big, everything within easy reach.

  3. My water comes from a deep artesian well and is very hard, with a lot of lime/calcium that leaves chalky white residue on everything. I put in a dual carbon and resin  filter. This reduces the problem but still the water is hard and still leaving white spots, stains etc. I have read on the internet about special filtartion devices that employ a salt chamber for softening water but no-one I've spoken to in Thailand seems to know about this. The company that supplied my filter (TMD) tells me the only treatment is resin, which I already have, or reverse osmosis. Would appreciuate hearing from anyone else who has solved this problem, thanks

    Try to add soda ash in a separate water tank. Soda ash makes the water very soft and removes stains. It does increase the PH level from 6.8 to 7.4 in my case.

    PS: sodium carbonate same as soda ash is used in soap to soften water(increase PH) and in bathroom, kitchen cleaners to remove stains.

    Thanks! Where in Thailand can one buy it and what is it called in Thai? And how much to add? Do I add it to the main tank (the water post-filtration, in which case it will remain in the water that comes into the house) or do it pre-filtration, or do I add a 3rd filtration tank, or what? Appreciate advice!

    They call it soda. You can buy it from Applied Biochemicals Bangkok Ph: 023625152 or Home and Pool Pattaya 01 8388042 or any other swimming pool supplier. Add 1 tea cup per day(it is harmless) in a 1000 lt water tank (pre filter) just after the well. The dirt can settle at the bottom and you open the valve at the bottom once per day. But the tank should be tall, about 2-3 meters.The outlet for the good water should be about halfway up.

    PS: The Thai-Chinese in Isaan do it the same way. A water supplier here pumps up real dirty water infested with calcium, iron etc His first cement tank is 10 meter high, open on top. The water is exposed to air (Oxygen) and all the dirt settles at the bottom. The second tank is for storage.

  4. Hi everyone, I am new to the site! Hello to all members!

    I am not new to Isaan, my partner is from Chaiyaphum, married 3 years and settled in UK. We want to build a house in the mubaan, not  to settle/retire in, but basically to make a home for my partners Mum and Dad.  We have got  the land (1 Rai) and land has been raised up to 1m above road etc and left for 12 months to settle. £5000 budget for the house, other additions like  perimeter wall can wait. Local labour will be involved and we can also be there when it is constructed to oversee. I have falang friends who have had work done but I am just fishing for info. Thanks!

  6. Roi Et,

    the filtersystem the company showed up with was quite fancy. It first injects chlorine, which oxidates the iron when the can easily be filtered out by a regular sand filter.

    The whole stuf, pumps, valves, backwash is controlled by a small computer.

    Only drawback: 90,000 Baht and it consumes around 5 Baht/cubic meter in chemicals and electricity.

    Did you buy manganese/carbon filter in Thailand? if so where and how much?

    I know the manganese takes out the iron.

    I'll look around a bit more before I commit to an investment this big...

    Thanks,

    Monty

    I bought my filter at Global Roi-et producrd by Mazuma, Bangkok. You can find these filters also at Homepro, Homeworks. My one is stainless steel 35cm diam and 120cm high filled with 33% each Manganese on top, Carbon in the middle and Silica sand at the bottom with manual backwash/rinse. Very effective :o , I filter 8000 lt per day.The backwash water is dark red. I think more Manganese would be ideal for me because I have very high iron and clay content. Bt 16,000 installed on site including 1hp pump.

  7. I'm sure cutting down all those trees over the last 40 years has absolutely nothing to do with the problem . . . :o

    Why are many countries having laws to keep the percentage of the forest area high as possible. Simple, trees are producing shade and keep the water in the ground and prevent errosion. Look at Switzerland: they keep the forrested area always at 25 % of the total surface. They prevented erosion and water level drop hundreds of years ago already. You find water everywhere.

    Andrew K Fletcher has some good practical ideas. :D Plant seedlings, small trees wherever you can, tell the school children about this. Start on a small scale. I planted already 30 trees on my 3 rai land and I will plant more. This land is really a non fertile :D Isaan clay dissapointment. But I try and try.

  8. Check out banlaesuan magazine (too bad they don't have an english version, I love this magazine), there is usually one business in there who advertises these. They look like a round stainless tank with a solar panel attached. We were quoted one here for 35,000 baht.

    SBK

    Sorry, other topic. Did you see some solar panels in Thailand to produce electricity.

    hi these panels are called "photo-VOLTaic cells" they are individual panels all linked together

    each one produces about 1.5 volts providing the sun is shining on them,whan a whole lot are linked-electrically together, the "array"usually produces 24volts,this is ok for lights and anything that can run on 24volts (tv /radio,but not any big appliances eg:aircon or anything that needs a lot of power

    there is normally2 or more batterys to store the electricity, so that you can use it at night pvcells only have limited use in a small installation.

    if you were to link lots of p /v /cells together and get a shed load of batterys

    you could then get an "inverter" this will turn a low voltage into a high voltage eg:24v into 110 or240 volts

    but the system will cost lots of bht! but with a big enough system you could run a house on it ,but it depends on how sunny it is!!(one guy in los uses fork lift truck batterys and an inverter very successfully)

    Andy

    Thanks a lot for your advice. :o Sheding a lot of batteries could be the solution to overcome peak demands like I have. I have 7000 bt monthly electricity bills mainly from water pumps, swimming pool pumps, refrigerators. I have 250 m2 roof which would be ideal for these p/v cells. I will try to find a supplier.

    PS: could you give me the contact of this guy using forklift batteries. Thanks again.

  9. Jai Dee,

    Thanks for the tip about the HCL to clean the walls. I have exactly the same problem on my walls where they get sprayed by the sprinklers...

    Roi Et,

    I'm having a company coming over on monday who'll show us  a filterinstallation.

    On the phone they guaranteed they can filter the iron out, after they recieved one liter of sample water I had to send to them...

    I'll post the results, might be usefull for other people having these problems.

    By he way, this high iron content is in no way harmfull for us, our bodies need a lot of it to transport oxygen throughout our bodies! I'd just prefer to ingest this iron in the form of a cool beer instead of murky brown water  :o  :D

    Monty

    I would be interested to hear the results of your filter testing. I installed lately a manganese/carbon filter to get rid of the remaining iron which I filter trough gravel. I have to do do a lot of backwashing with this filter to get sparkling water needed for my pool and bungalows. Maybe I selected a to small filter, only 100cm high. If I read the recommended website of Ajarn a pure manganese filter could be the solution.

    Waiting your results, thanks

    Too much Iron can be problematic.... Here's some info on dealing with Iron in your water and in your body... http://www.dnr.state.wi.us/org/water/dwg/iron.htm

    THANKs Ajarn

    Great site. Real helpful information :o

  12. About 20 % of the pool water get lost per month due to evaporation and backwash(cleaning)

    Our pool is 7 x 11 meters but we only loose a little water.

    20 percent sounds very high to me.

    My pool is 8x16x1,6 meters and a 4x4 m children pool. It is 180 m3 . This is a public pool and more than 30 chidren splash at the same time weekends. Total more than 100 splashers on a Saturday. During the week we have an average of 40 visitors per day. I really loose so much water, no crack in the pool, very solid built overflow system.

    Because I use borewater I have to make a bit more backwash. And I use also a bit more Chlorine of course.

  13. I just did a 30m bore and the water I get is close to unusable due to very high iron content. It comes out the pump crystal clear but upon contact with the air it turns brown.

    Bring it in contact with chlorine and it immediately turns deep red. Chlorine is an oxidator so it's just the iron being broken down (rust  :o )

    The reason of the bore being 30 m is that you normally need an approval to go deeper then that. The dumbass from the bore company didn't tell this to me (to save the cost of the approval) but he(me actually) got unlucky when some local official turned up and inquired to that approval.

    So we were stuck at 30m, with absolute unusable water...

    If you get a good workin deep well, you'll have water that's much cheaper then company water. About 1 baht/cubic meter it will cost you, taking into account the electricity used, depreciation of the pump etc.

    Company water is at least 15 fold, so if you have a big garden and a big waterconsuming swimmingpool your boring cost will be won back many times over...

    And the waterflow won't stop at the end of the dry season  :D

    I had exactly the same problem with iron content. I store the water in a 3 meter high tank, 1 m diameter filled with gravel 30 % at the bottom. I throw some Soda Ash in the tank and this is washing the water. Twice a day I empty 10 % of the tank at the bottom.

  14. HI

    Have ben reading the threads for a few months now and your last post struck a cord with me, as I am curently writing a bok on desertification, its causes and how this cataclysmic problem can begin to be addressed.

    I made a prediction that following the tsunami coastal destruction, there would be an initial increase in rainfall, followed by an unpresedented drought. I hope to god I have got this wrong.

    The problem of removal of trees and vegetation, exposing huge sandy coastal areas to the suns energy, radiates thermals into the sky. On the face of it, one would not believe that the rising thermals from the hot dry sandy beaches could prevent rains from falling. However, it is becoming more evident that moisture arising from the oceans is prevented from crossing on to the lands by these thermal barriers. Indeed, this is how the Sahara desert has become so prolific in spreading to the size of 2x australia, and is now moving rapidly up through Spain.

    The wake up call that Thailand is about to experience over the coming years may cause people to sit up and listen. It may even show the absolute futility in monoculture cash-crops.

    “A nation that destroys it’s soil, destroys itself."

    -- President Franklin D. Roosevelt

    Andrew

    WAKE UP CALL!

    Not a good report I am afraid but what can you expect from what is happening in the last 30 years here in Thailand?

    Dear Mr. Fletcher

    It happened, no more forest, monoculture, the water level is lowering more every season, the farmers still burn the rice fields, Isaan could be a desert in 30 years.

    DO YOU HAVE PRACTICAL SOLUTIONS FOR THAILAND.

    I have noticed there is a lot of government money spent for irrigation projects. In parts of Isaan water is supplied to the farmers trough these projects. Lack of finances for running respective water pumps is the problem, could be a challenge, maybe you know where to raise funds.

    Planting trees over large areas would be another challenge , wouldnt it. Financing this is of course the real challenge, how about getting funds allocated trough your resources or connections.

    Stop burning rice fields is another issue. How about printing leaflets in Thai about the positive sides of not burning the rice fields. Distribution of leaflets twice a year could maybe be a practical idea.

    How about getting around the chemical companies and teaching diversified farming on site . On site education in the small villages could be an idea.

    Mr. Fletcher

    I know you are the specialist, you have the respective connections and you are prepared to meet some challenges to help the the Thai farmers.

  15. What do you want to know ?

    Thanks for the response Thetyim,

    As I said, I'm thinking of using bore or well water to water the garden, but want to weigh up the costs before actually embarking... it may be cheaper just to use town water.

    The ground water table is only about a metre below the surface. How deep should one go to get reasonably clean water? What sort of arrangement would you recommend? And what would be the indicative costs?

    30 meters deep could be sufficient for good quality water. But make a 5 day water test at this depth, maybe you have to go deeper. Town water can be very expensive for a pool. About 20 % of the pool water get lost per month due to evaporation and backwash(cleaning)

    PS: Do not forget to put your house and pool on 30 cm stilts about 3m down with 4 m2 foundations otherwise you will have a floating house and definetely a cracking pool.

  16. Last year we opened a bankaccount for my (Thai) wife and one for myself at Bank of Ayutthaya.

    At that time we visited Thailand for a holiday, only a visa-stamp for 30 days in my passport.

    For 'our' home-address we gave them the home address of my mother in law. No questions asked.

    Walked outside, with two bankaccount-booklets and two ATM-cards.

    Legal or illigal, I don't know.

    Same experience as yours, Ayudhya no problem, got ATM with Tourist Visa and I gave them my mother in laws address.

    Bank of Asia asked for address confirmation from Immigration, residence permit. As I asked them why so much problems :o they answered: We can only open accounts for foreigners with residence permit.

  17. Apparently it's true and has been for some time.

    Thats the law

    I hope he lowered your case price, but I'll bet he didn't, even though the original price had the extra cost of printing included... Profits before refunds, of course :o

    He did not lower the price. He used the standard excuse with a big smile :D , production costs are gone up lately, we have to cover this increase.

  19. 1.  Pension letter is not required for support Thai wife extension.  Not sure about long stay (retirement) extension. (assuming money in the bank)

    2.  Up to you. :D   The support wife is lower because you have a valid reason to want to live here rather than a desire.  Has nothing to do with supporting two or one.

    3.  No and was not aware long stay for retirement required any such letter.

    4.  Support Thai wife can work, lower bank/income requirements, physical not required.  Long stay for retirement wife not required, extension may be issued same day rather than 6 week wait.

    5.  Walk in turn left/right and get form, fill out, pay 1,900 baht fee, wait, directed to office in rear directly in front of entry doors, go to desks at right end take number or sit down if nobody waiting, have interview (with wife if marriage) and hand in required paperwork.  This should be done during last 30 days of a 90 day entry.

    Lopburi

    You seem to have experience about this.

    Do you think I could change from retirement to support Thai wife visa. You say having a valid reason to live here and has nothing to do with supporting two or one. I always show up at immigration with my wife for renewal of my retirement visa. They told me because I am 57 years I should stick to the retirement visa, but they did not give any reason.

    I suspect it is easier for immigration as they do not have to investigate relationships. They originally got out paperwork for retirement when I started at age 58 or so and I just mentioned support and they said no problem and did the marriage type so I am sure they can do it. You should be prepared with photos together the first time and have wife bring home register as well as ID card.

    Lopburi

    Thanks a lot for your very valuable reply :D . Next time I will do as you suggest. In fact the very first time I went to Immigration in Bangkok my wife showed all the documents as suggested by the Thai consulate in Europe: home register, ID card , Marriage certificate translated by Thai Consulate

    Because I had much more than 800k Bt on my Thai bank account at the time of application, the immigration officer smiled :o , said you have enough money and stamped retirement in my passport.

    Thanks again

  20. Contemplating the next house to build/rebuild in the Isaan: Raised or Ground Level. I like the idea of the more traditional style raised Isaan house, but note that they eventually get built out (that is, under), anyway. If that's going to happen, why not just build ground level and go up? My wife does not like ground level because of the ease of access for frogs, geckos, snakes and other creepy crawlers to get in the house. Anyone have some experience with pest control at ground zero?  :o

    My in laws have a ground level house. What a mess. There is no possible pest control at all. Your wife knows from experience. I would like to here from some insiders how to do this. I built my house 50 cm above ground on cement pillars and access the ground or first floor via 50 cm stairs. You find a lot of new houses in Isaan built like this. On the side of the carport I filled up sand like a slope, but must keep the carport always clean. Other sections of the house no problem at all. :D

  22. Here we go again.......people in this forum having a swipe at the Thais !!!!!

    Very seldom are large projects finished on time anywhere in the world and its certainly common pratice in the uk to estimate completion by percentage.

    86% may be a little precise but with the monies involved it may be relevant.

    We must remember, that at least for the moment the terminal has not collapsed, as happened at both Heathrow and Paris !!!!!  We should not be critical for critisism sake.

    Swiping seems to be common practice in this forum.

    Large projects like this always create new challenges during construction and add to the delay. Just look at the challenge to build runways on soft ground. At the end the testing of software for running all these facilities creates new surprises etc, etc. Highly rated american, european companies often face problems with projects of this size. So this happens anywhere in the world.

  23. Hi and thanks for y answer.

    It must be better to drill and use a pipe and lower a water-pump, what do y thing?

    I guess that you are talking of a submersible pump. A decent one will provide water from 35 to 40 metres down. However, you'll need a "well" of at least 300 mm diameter in order to lower the pump down. A suction pump only needs a casing of, say 100 mm, diameter to accommodate the suction pipe (25 - 35 mm).

    I've got a submersible pump, we had to go down about 50-60 meters, as I'm on a bit of a hill, I'm sure its fits down a 4 inch pipe. Mines a 2 hp pump and the water comes out very clean, and supplies the farm, house and shop. You could probably drink it with no problem (I dont) but we do use it for cooking/coffe ect. I've got a 16,000 liter header tank, which with the farm is only enough for about 2-3 days if I have a problem, but I can switch back to gov water if I need to. I can pump about 4000 liters an hour, but it cost the best part of 100,000 with everything (drilling, pump, tank ect). Oh its always best to drill in the dryest part of the year as the water table is at its lowest.

    Is this 16,000 liter header tank made of cement and how big is it, I would like to know. Thanks for your info.
