khao tao water

Post by big jimmy »

Hi guys..I need some help on this one if you can...the estate where I have a home , soi 126, is recieving very poor water supply.. .now I have heard that they are repairing the pipe from Pranburi, whether that is true or not I don't know but the people who live there permanently, as I don't , are not getting water.

What I would like to know,if any of you have heard anything..is Khao Tao to be cut off from water supply from Hua Hin and Pranburi ?.. I can't believe that that would happen but you never know...is there any one out there who lives in this area experiencing the same water supply problem as soi126 or is this just restricted to 126 ? ?
Any ifo. rumour or not would be appreciated...thanks.....

I can't confirm this, but I was once told that from soi 96 and southwards on, you are supplied with water from the reservoir close to the flyover and not from the reservoir in Pranburi.
What the Tessabahn homepage said was that repair works took place between the 22nd and 25th of last month.

During my time in Hua Hin I have heard about and experienced regular cuts in the water supply, often lasting up to a week or more, but I have never heard an explanation for them, so i have always assumed in the past that it was due to repairs and maintenance. However more recently I read on here on another thread that it is a rolling programme by the water company where different areas get cut off in sequence to allow the other areas to still have water. I fear this problem is going to become more frequent as more and more developments and individuals dig their own wells, and/or start collecting rainwater, thus depleting the supply even more (although also reducing demand). This is one of the infrastructure problems that the local authority seriously needs to address if they aren't already.

The reservoir in Hua Hijn is a header. The feed comes from the Pran Buri Dam and the Kang Krachan dam in Petchaburi mainly but there are also some smaller ones in the Pala-U area.

Wanderlust, I do not understand the logic in your statement that well digging and surface water collection will exacerbate the problem. Surely the water collected for use in Hua Hin is way above any wells or surface collectors.

In my experience water runs downhill. Water from the main reservoirs to the headers is piped, I thought.

Big Jimmy, if you pop down to the reservoir mentioned by Norseman you will get a clue as to whether or not there is enough water.

I understand that there was a water shortage all over the region two years ago but the continual rain of last year brought the water table and reservoir levels up to normal. That was what was published in the Thai newspapers anyway. Rainfall has been above average for the last two years but demand has increased also.

BTW, dams (reservoirs) only collect a fraction of the water deposited by rain. A household rainfall collector only traps a tiny percentage of that percentage.

My understanding is that the water problems in Hua Hin are caused by the tessabahn not keeping the infrastructure in line with the growing demand.

The same problem applies to electricity, transport and communications. They are quite happy raking in all the extra revenue that growth supplies to them but don't seem to like re-investing it.

What is needed in Hua Hin is a great big oil refinery, a nuclear power station and a metal re-processing plant on the beach accompanied by some big fat cash handouts.

Then you might see an improvement in supply.

Guess,
What i meant was that if any water is taken out of the 'system' then it will reduce what is available for others; if rainwater is collected it can't then make its way back into the skies and fall as rain again and replenish reservoirs etc. Equally for every well that is dug the amount of water in circulation is reduced. I also haven't seen too many sewage treatment plants around that extract the water from the waste either. Does it all flow into the sea and get recycled that way? Physical geography was never my strongest subject, so maybe my assessment is wrong?

Jimmy, I'm in soi 126 (Thai Willage). I've consulted the oracle and she tells me (having asked the couple who take care of the gardens etc here) that our water comes from Pranburi and that there hasn't been a problem for a while. The pressure from the mains isn't great, but all that means is that our tank is slow to re-fill. Something to do with being slightly uphill apparently.

Can't be more help, this is all too technical for me... :?
This is the way

OK I get your drift. The water is only diverted on a very small scale.As you wrote earlier the demand from the water company will be less if the houses use wells and rain water collectors.

You may not want to think about it but the water either evaporates into the atmosphere and falls again as fresh rain 1% (free water treatment) OR is chucked out as sewage 99%. It then either gets picked by a water treatment plant and put into the sea or back into the fresh supply OR it seeps down onto the natural underground system where it may lie until someone digs a well or there are earth tremors.

The amount of water on the planet does not change. It just moves around and changes from solid to liquid and to gas and back again.

Your observation about water treatment plants will give you a clue as to what happens in Thailand.

True, among other factors. The calculation requires the knowledge of communal demand, size of bores (pipes) and head of water ( the gravitational force that you get from the reservoir to you tap). The greater the distance in altitude your outlet is from the reservoir the greater the pressure. If it goes uphill at any point on its journey you just reduce the pressure again.

The ways around problems are to fit pumps to suck the water from the system and gravity feeds (roof height storage tanks).

However all this is only relevant if the water company are allowing any water into your section of the system.

Your section may just cover a few houses or a single estate.

The first port of call must be the water company.

Thailand recognised about 20 years ago that fresh water supply was a necessity for life and ensure that everybody could access it. Older people can teach you all sorts of ways of purifying water for cleaning and drinking.

So to have the supply cut off for long periods is nonsense and would only be expected in a disaster zone.

Well, (sorry) we must be in a disaster zone.
About 10 days ago our water was cut off for three days and nearly every other day it was cut off for most of the day.
( A bit further South than 126)
I never checked the relevant authority (Why waste time) but I heard various excuses including system maintenance and giving all the pressure to a large nearby construction project to the detriment of everyone else.
I tend to believe the latter.

Drawing below of the 'Ground Water' system, if anyone's interested.
I have added on this drawing the 'deep wells' that developments install, I believe, please dont quote me on it, that they draw from 'confined aquafiers' (whatever the heck they may be :? )

How would you handle a loss of electricity within the system?

I'm thinking of buying a 2000Ltr rain water collector. It's about 8000 THB. One good dousing of the roof and it could fill in an afternoon and last a year.

Not sure about old biddies to tell me how to clean the rain water. Is it necessary? Right now I just drink it.

If you mount the tank as high as you can or get a really tall skinnier type, when your pump power is off you still get some flow.
A rain collection tank is a good idea, many use it for watering the garden only, sharing the load so to speak.

Mr P if you using one of those little wine glasses just now, let me know and I'll drop a 2L beer pitcher off for you :D

These days, if you bring me a 2L beer pitcher, I'll stick a plant in it. :wink:

Good stuff SJ. A picture paints a thousand words.

Mr. Plum. Fresh rainwater is OK as you have proven but after one year? I wouldn't chance it. I suppose you could add a few pots of chillies, boil it up and call it Tom Yam Gung.

I wasn't seriously suggesting that you consult an old biddie. Its just an explanation of what they did before the water supply existed. Lots of Allum apparently. I always wondered what that was used for.

I still say that the water company should be nagged and nagged until you get the answer you want even if it does seem a waste of time to start with. What do you have to lose?

Get the local Thai newspapers informed and even report it to the MIB. Ideally get all those affected to do the same. If they are cutting off your supply to feed a building site then they are getting under the counter payments to do so. If people don't stand up to these tossers they will just get more bold.
