  1. I don't wish to be pessimistic, but I have drilled a couple of unsuccessful wells in Pranburi for pineapple farms and your location does not sound too promising. If you can send more exact coordinates I can check the general groundwater hydrogeology and previous drilling history on some maps I have prepared by the Groundwater Division of the (old) Department of Mineral Resources.

  2. My Thai project manager was just quoted 120,000 baht for:

    9" bore-hole

    up to 100m deep (they said 50-70m is probably what we'll end up needing)

    including submersible pump and motor etc

    screw-together tubing

    10% deposit

    40% on completion and working after a few weeks

    remaining 50% after 12 months if everything is still ok

    will take about 10 to 20 days to do unless they hit a ton of granite (same price, their hard luck)

    Location is Phitsnulok. Seems quite a fair deal to me?

    I have about 120 rai to supply, and new lakes to build/fill etc.

    Know this is an old post...but any contacts for this mob ?

    Sounds like a very fair deal.

    With a deal like that, they would not have stayed in business for more than a couple of months so it might be best to start looking from scratch.

  3. I met a girl in Chiangmai who had a conch shell tattooed on her inner thigh. The colour was exquisitely realistic and it was just small enough that it could be discreetly hidden when wearing shorts.

    It worked too! When you held your ear close to it, you could almost imagine you were smelling the ocean.

  4. - I've always seen the No Riff-Raff policy at The Red Lion as a comic deterrent, it hasn't put me off! I pop in every so often and enjoy good service and the odd chat with that strange John Cleese character.

    Thanks for that link, I hadn't seen it before. I know the people in the picture at the bar so the "no riff-raff" policy is obviously not enforced.

  5. I have driven the road many times and everybody I know who does it regularly uses the same route. The last time I did it was in rainy weather and I had my GPS on. Nong Khai to Lampang was 555km and the driving time was jut under 7 hours so Chiangmai - Udon should be about 7.5 hours. Denchai-Chatrakarn-Nakhon Thai-Phu Rua-Wang Saphung-Nong Bua Lamphu.

  6. I have seen pickups transporting fish driving around with blowers belt driven by a small petrol engine. The blowers look like the ones on GM (Detroit) Diesels from of the two stroke series, e.g. 53 or 71, with any number of cylinders. Nissan also used to have a two stroke diesel UD series that had a very similar blower. The output side looked like it simply had a flange bolted on with an outlet to a hose. I could not see any method for lubrication attached - maybe the speed is kept low enough by the pulley size selection that it is not critical. I would think they would have high volume with low pressure, possibly very suitable for fish tanks.

    I guess you would look for them at Sieng Kong shops in the area you live.

  7. I'm going to say Khao Sarn Road, which I know is wrong, but it's an attempt to keep this thread going as I like the idea.

    Good luck, sorensen

    Since 2long likes Khao Sarn Road so much, let have a look at it in the past.

    Well it's a good picture of Ratchadamnoen Avenue anyway.

  8. You have most likely seen this statue before and passed by it a million times, if you live in Bangkok. Where is it located now?

    Is it the Erawan Shrine, now located at the Hyatt Erawan?

  9. but high in iron

    I have had one borehole, done about 4 years ago, which was very high in dissolved iron (ferrous water).

    Virtually impossible to use as household water as everything stains yellow, and bacteria starts growing in those stains.

    Iron is pretty difficult/expensive to filter out of the water especially if concentration is high.

    I used Birm as filter media, and even that could not take out all the iron!

    I find iron to be one of the easier contaminants to remove. If the water is aerated, the ferrous iron turns to ferric and a sand filter will remove it. Still a nuisance as the filter has to be backwashed frequently.

  10. Thanks for that insight Boksida.

    Here's a Google Earth of the plot location if it gives you any more specific information that you are able to comment on. No pineapple plantations up my road I'm afraid. Many thanks.

    You may be lucky as the valley between the two hills may be a natural water course although it looks like your block maybe a little too high to get the most benefit. If it exists, the water would be in the sediments near to the surface or in a weathered granite layer immediately below this but still shallow. I doubt it would be worth the investment to continue driling after you had hit solid rock.

    Can you get any information on whether groundwater is being used at the Black Mountain Golf Course - it looks like similar geology?

  11. Hi all,

    I need to drill for water in the Hua Hin area, close to the base of a mountain and worry what happens if they don't find any water after drilling for 100m. The land plot has no other houses near and is 1 rai in size. Info/education on anyone's experience would be very welcome.

    Cheers.

    I have just had a look at a hydrogeological map of your area. It classes the area between the coast and the granite hills to the west as an area with unconsolidated and semi-consolidated sediments, normally with fresh water, but high in iron, with yields up to 5 m3/hr. Water is available in the granite area (the hills) from joints or areas of decomposed granite, which means this is a matter of luck as much as anything. Yields range from almost nothing to 10 m3/hr. Closer towards Cha-am there is a better aquifer between the coastal one and the hills.

    I don't know if it is near your place, but there were some wells drilled at the Dole pineapple plantation in the 70s and some of them had yields good enough for irrigation and others were very poor. A reservoir had been built as a Royal Project nearby and I suspected that the good wells may have had some underground communication with that.
