  1. I once took my Jeep Cherokee across the border at Mae Sai. The people I was visiting found it quite amusing to take me to a showroom in Tachilek specializing in 4WD vehicles stolen in Thailand. We even crossed back into Thailand at a ford across the creek which remains below water level so it is not visible from the air.

    Across the border may be the place to start looking. Good luck.

  2. Hey the TVers....

    could somebody, please(!), advise with the relevant technical know-how (indepth knowledge please, not just "I done it this way once and it worked.....") on the following scenario:

    130m deep borehole

    6" bore

    what pump should I be using (how many HP? flow rate? etc.... as many specs as possible, please?)

    what diameter should the pump be? (surely the same (okay, a few mills. less) than the bore, right?

    any advice or experiences with particular models? Brands? etc.....

    living on Koh Lanta, red mud......... SOME dodgy, "khee gong" locals...... :D spewing forth some crazy figures and facts!?! :o:D

    thanking anyone in advance for your help

    all the best

    Waterworks,

    I can send you specs on a pump but need to know a couple of things first:

    1. How much water do you need? No point in getting too large a pump as it will cost extra in electricity bills with no gain.

    2. Has any testing been done on your well? Casing size is no guarantee of yield. You should at least know what the static water level is and, hopefully, pumping water level at a specified rate.

    3. What is the internal diameter of your well casing? Some nominal 6" diameter pumps will not fit in 6" heavy wall casing. If you can use a 4" or 5" pump you will have fewer future maintenance problems.

    4. Is your casing PVC or steel? Is the well cased to total depth? If so, what type of screen or slotted pipe was used in the entrance area and at what depth is it? It is common to use a smaller diameter screen than well casing - has this been done in your well?

    5. What surface equipment or lift do you have that could add to pressure requirements?

    4" submersible pumps are available at hardware stores nationwide and occasionally 6" pumps as well. Don't go cheap on your pump column pipe as you will regret it later.

    If you can post some more information I can probably send you a .pdf file with pump specifications or direct you to a suitable website.

  3. As you obviously know the answer, why don't you just identify it yourself Boksida?

    I'm going to be traveling for a few days so I don't know if I can help with any hints if I post a new one. Thought I would give somebody else a shot.

  4. Is the building in the foreground a border crossing or something more mundane like a ticket office for a ferry docking at the thing that looks like a causeway or long jetty leading off to the right?

  5. Not attempting to arouse any more of the all too much American bashing that is so common on this forum ( Americans are always the first to help worldwide when people are hurting, yet the first to be shit upon from others, but that is for another thread someday...), but as long as there is discussion of the differences between American and "proper English" a question arises. I have noticed the word "whinging" reffered to time and time again and am curious if that is the "proper" English way of spelling the word..."whining" as in "to whine" or not. Again just curious

    Have a butcher's at this

  6. The photo below is an example of the maps available from the Government. This particular one is of Northern Thailand - dark blue areas are the best, grading through blue then green and then brown represents hard rock areas with low water well yields. I think they are very professionally researched and prepared.

    Unfortunately I have laminated all the maps I have into wall mounts and have no other way to reproduce them other than photographing.

  7. You can buy hydrogeological maps of all areas of Thailand from the Groundwater Division, which I think is now part of the Ministry of Science and Environment. They are color coded and show well yields, depths, static water level and some basic water chemistry. Books are also available showing data obtained from the huge number of wells drilled by government entities.

    As a general answer to your question, I would say along the major river basins is your best bet. This means the Chao Phraya in the Central Plains area and the four major basins in northern Thailand. Generally speaking, depths are in the 100 to 300 metre range and yields of over 100 cu.m./hour can be obtained. The best wells in Bangkok are now around 600 metres deep as the shallower aquifers have been contaminated and depleted by over pumping.

    Unfortunately the north-east does not have much potential for large scale production with the exception of a couple of limited areas and industry is already exploiting these.

    I am only referring to wells producing water meeting drinking water quality standards.

  8. Do they speak Catalan in Santiago?

    Interesting point. According to Wikipedia, everyone in Barcelona can speak Spanish but around 75% of the population can also speak Catalan and 47% of them can read it. Seems strange to me that they also say that 99% can understand it, so I would have thought a higher percentage could also speak it.

  9. There's another reasonably easy way to get mushy peas in Thailand. The larger supermarkets often have cans of Thai A-D brand "Processed Green Peas". I can't remember the price but it is not much. Pour the brine out of the can and boil the peas in fresh water. Keep adding water if required until you get the desired degree of mushiness and then they're ready to slather on your meat pie.

  10. Ok, yes it's York. Didn't notice you could see the file name as I was logged in and you can only see the file name if you're not logged in, I guess. Here's another one.
