Shrinking Pattaya Reservoirs

Recommended Posts

So what do we do to prepare for a dry season water shortage?

I assume/hope it will not affect bottled water. Can anyone confirm that?

Bottled water in Thailand comes from a combination of sources; tap, well, underground, and springs.

Most of Thailand's spring water comes from the north, and in the central regions only 3 or 4 companies are licensed to pump water from underground sources to make bottled water.

In the Pattaya area bottled water unless sold/distributed from the above northern sources, tends to be from well and tap water which will not dry up as much as become more costly to produce as the water has a higher mineral and salts/calcium carbonates content in drought conditions and becomes more expensive to filter.

But about the only effects on consumers will be pricing will go up nominally; likely not enough to notice, e.g., a 12-pack of 600 Ml bottles at Makro might go from 45 to 49 baht.

For houses one has to order a truck/ tanker to come deliver and fill your tank up. I have never had to do this in my current place, but my prior rental I had to do it quite often. The pipework was rubbish there, always failing and even when there was water it had hardly any pressure and those with below ground tanks fared better. Trouble is once this system gets organised and palms are being greased, one finds utility water is being cut more often by a guy with some money in his pocket.

My neighbour has an automatic sprinkler system and a monthly water bill of around 4000 baht, that won't help supplies. Another actually had a bore hole but it has dried up. My Mrs uses water like it is a never ending supply, house cleaning day a small pool's worth gets used. Why anyone needs to flush a toilet 3 times per visit I never could understand.

Nice day for a bike ride, so took my mtn bike out to Mabprachan reservoir to see if it was now low enough to ride across.

Entered the bike path around the reservoir on the SW end.
49197595636_49da5c9813_b.jpg

Compared to the pic from last month, the water level at the overflow outlet looks to be down another meter. Pic from today.
49197596456_95066a8bf8_b.jpg

And from 10 Nov
49047410596_961a07bc09_b.jpg

Imagine the volume of water lost from the reservoir. The high water mark is the dark patch of concrete about 6m up from the water.
49197596401_fe647c04a6_b.jpg

The new and quite a bit larger beach on the NW end.

49197797502_f8129b5f9b_b.jpg

Unfortunately my hope of being able to ride across the lake bottom was dashed when I encountered numerous channels that blocked me from my goal.
49197098593_532e265f9f_b.jpg

49197098518_0ab09c9501_b.jpg

And no, I wasn't about to cheat by using this "bridge".
49197098558_71b414316b_b.jpg

Still an island, but not for much longer.
49197098423_0f2f2f3675_b.jpg

Same view from 10 Nov
49047622372_fe10b46765_b.jpg

With another 5+ months to go before the next rainy season, there's a good chance this island will look like it did on 7 Sept 2015.
49047404846_972bd0f141_b.jpg

The birds don't see to be bothered by the low water level.
49197797272_8afc2054a5_b.jpg

But this guy can no longer cast a line from his front porch.
49197797187_838c67fb5a_b.jpg

Same view from 10 Nov
49046906378_124364c668_b.jpg

I'm now on the north end looking south when I noticed more and more of the birds taking flight.
49197098313_f7413c40cd_b.jpg

49197595926_63b635f0b1_b.jpg

I use to fly sailplanes for fun and I'm pretty sure what happened is my riding the mtn bike across the dry ground on the north end kicked loose a thermal. Use to see that quite a bit when I flew in Wisconsin. When I was getting low I'd look for a farmer plowing his field and it was almost a sure bet if I loitered around the area for a few minutes I would be rewarded with a thermal to gain back altitude in. Anyhoo, the birds probably saw a few of their friends having fun in the thermal and soon the whole extended family joined them.

 

They might have to soon rename the reservoir to Mabprachan Desert.
49197595876_aa71147638_b.jpg

These guys standing around in the middle of the reservoir demonstrate it isn't that deep in parts.
49197797072_49bab21078_b.jpg

49197098228_38b0a2e194_b.jpg

49197797027_5d23d8e5d8_b.jpg

This is another marker of how low the water level is.
49197796967_bfcda3781d_b.jpg

Soon the outlet channel will be higher than the water and this part will turn into a stagnant pond.

I was in an 'ahem' 'establishment' yesterday and they had no incoming water. Whether it was anything to do with the damned roadworks outside I am unsure. It doesn't bide well for the rest of the dry season.

Along 3240 on the north side of the reservoir they're laying and connecting new water pipes. 

49197098063_f3b346415f_b.jpg

There's also a notice a lot of the darkside will be without water today. Although I saw a post on another forum that said the water outages have been happening for a few days now.

They had one of those big tubs and a plastic cup, and fortunately for me (not for who pays the bills), I think it had previously been topped off from the electric shower. So tepid. Those run down places without water tanks, pumps and electric showers will not be seeing my custom. 

Oh... and I often ask for lotion....

It's been two weeks and two days since the last update, so hopped on my bike and had a very enjoyable ride this morning around what remains of Mabprachan Reservoir.

Starting again on the southwest side.
49277132681_59559bd117_b.jpg

More spots that were previously underwater are now exposed.
49277132581_69c2ae6812_b.jpg

Wish they would mount a water level gage to this structure. I'm estimating the water is down another 1/2 meter or so since the last update.
49276665078_a7f31389f0_b.jpg

49277334867_d51a2b030c_b.jpg

I wonder how much longer it will be before this guy can walk to his fishing camp.
49277133161_015291525e_b.jpg

They're now having to pump water from the low spots.
49277334682_35953d90a1_b.jpg

49277132691_0c23e7862b_b.jpg

Another couple of weeks and there will be no need for a bridge over this channel.
49277133066_ed1ba69937_b.jpg

A babbling brook in the middle of what was once a lake.
49277334632_3d5a5c622a_b.jpg

49276664953_67fcde11a7_b.jpg

The island is now a peninsula.
49276664858_29cc95001e_b.jpg

49277132936_6239be63c3_b.jpg

On the north end looking south.
49276664773_88a057dc8a_b.jpg

Fishing is a lot easier when they fish are trapped in what remains of the water on the north end.
49277334427_716bbc4256_b.jpg

Mabprachan is fast becoming a lush meadow. Can't really call it "lush" as the dominant flora are thorn bushes.
49277132841_1b7c9abb04_b.jpg

A bit of a technical ride to get out to the far end of this exposed rock outcropping.
49276664633_5d16eba786_b.jpg

Had to ride over a lot of broken shells and gnarly rocks to get to the far end, but this was the view looking back.
49277334397_9cf59dbd73_b.jpg

And the view towards the dam at the west end of the reservoir.
49276664623_c9ff462c47_b.jpg

49276664463_27ed599b09_b.jpg

Now back at the southwest side. I see they've closed off the channel into the pond within a lake and are now having to pump water into the pond.
49276664608_b983e2a76c_b.jpg

49277334287_905f17a7bb_b.jpg

At the rate the water level is dropping it doesn't bode well for the Pattaya area in the coming months. As the next rainy season is a long way off, I expect we'll see severe water rationing measures to conserve what little remains of the water supply.

As much rain as Thailand gets, it's a wonder how it's possible there can be a water shortage. This is just poor mismanagement of resources. We are not living in a desert or arid region. The average annual rainfall is 1117.6mm, that's a little more than Washington DC and about double what London gets (583.6mm).

Made it out to Huai Chak Nok Reservoir today. Water level is looking pretty dire there too. Here's the view from the dam end on the NW side.

A lot of what was once under water on the south end of the dam is now dry.
49285770357_da3376ab4c_b.jpg

Here's a screenshot of the satellite view of the reservoir with a maker of where the above pic was taken. Image is from Nov, 2018 and gives an idea of how far the water has receded.
49285635476_14000ec029_b.jpg

49285557906_c4ec43c82b_b.jpg

They have pumps going to move trapped water on the south end into what remains of the reservoir.
49285557851_be2903aff2_b.jpg

It's going to be quite a while before this overflow outlet will be needed again.

Time for another bi-weekly update on the shrinking Mabprachan Reservoir. For this update the Google Earth screenshot below has markers that identify where a picture was taken. It will also give you a good idea of how much water has been lost from the reservoir. Satellite image is from Nov 5, 2018.

Pic 2: Pretty soon the pumping station will be sucking more sand than water.
49365367778_fa57eef2fb_b.jpg

This water intake has been left high and dry for some time now.
49365367643_ebb1968a7f_b.jpg

Pic 3: The water in the channel is now shallow enough to walk across, but the problem is you'd be up to your knees in mud.
49366044897_639a7dab88_b.jpg

Pic 4: Hard to see in this pic, but you can now walk, or in my case ride a mtn bike to the island without getting wet.

They are putting new pipes in around my area, and as per usual, the digging hit the old pipes and a nearby street became a river. My Mrs asked the security man of a village there, did you call water people for fix... he looked at her as if she was mad, sort of 'why should I get involved?' Nobody arrived for a long time, these things often seem to happen on a Friday late afternoon. My water was out all night, but back on in the morning. Other than that, the water seems to be going off, or very low pressure, late mornings to mid afternoon now, but I have a tank. Anybody else getting regular cuts?

I have two tanks. The one that's topped up from the city water supply is underground so can't tell when the supply is cut. The second one is above ground and topped up from the underground tank. That tank then feeds the house through a pressure booster pump, so always have good water pressure.

Since my lady's main hobby is her garden, I estimate we use about 100L every two days for watering the garden. For that I just installed a 1000L tank to collect rainwater runoff from the roof gutters. All we need now is a good downpour to fill that tank and we're good for 20 days with no rain.

My rainwater collection is off the gutter into 2 plastic bins.... that is all pretty much gone. A single tank for house supply, 2500l can keep me going probably for a week but only if the Mrs is told. I run all of it through the tank as it comes out cleaner and I even add a touch of chlorine to it...... so if my utility supply goes off I wouldn't know unless I took a look at the pressure gauge... yes I put one in! If my electric is off I can bypass the tank. 

I was in the garden yesterday listening to the pump kick in and out as my Mrs cleaned house, boy can that woman waste water. Thais seem to really like spray nozzles!

Seventeen days since the last update so time for another shrinking Mabprachan Reservoir update. Here's the Google Earth overview of the route this morning with markers where the pictures were taken (Satellite image Nov 5, 2018).

49452862368_e5c6501f58_b.jpg

Pic 7: What remains in this pocket of water is too small for the big blue pump. They're now using a smaller pump just on the other side of the big pump.
49453575352_e6fa31160c_b.jpg

Pic 8: As it turns out I didn't need to use the rickety log bridge. There was a land bridge on the other side of the pump in the above picture that allowed me to ride my mtn bike to the other side.
49453575307_b958c36f05_b.jpg

49452861588_83246a1c5b_b.jpg

At the current rate of water consumption, my guess is we have at most two months of water left in the reservoir.
The Chonburi government really needs to act now to protect what little remains of the main water supply for Pattaya, and pigs may fly.

Did a bit of internet sleuthing and found this document with a list of reservoirs and their users. Turns out there are nine that provide water to Pattaya.

Wish I could task a satellite for real time imagery, but as I'm retired CIA I guess I'll have to do it the old fashion way with feet on the ground to get pics of the current water levels.

More internet sleuthing led me to an article in the Bangkok Post from 2014 that made for interesting reading.
Running taps a pipe dream in Pattaya

And from that article...
"Mr Wanchai said East Water only delivers raw water to treatment plants run by the PWA in Pattaya. At that point, the company’s responsibility ends, and it is up to the PWA to take care of the infrastructure which processes the raw water and delivers it to people’s homes."

"Pattaya water is sourced from five different natural reservoirs, while the PWA also has the contract to buy raw water from East Water in case water from the reservoirs is not enough to meet demand.
Mr Wanchai from East Water explained that Chon Buri usually suffers more shortages than neighbouring Rayong province since the water reservoir in the area is small and unable to feed the whole town at the same time."

Looking at the the East Water website I found this image of the water grid. Keep in mind this grid doesn't show the infrastructure PWA uses to source water from the reservoirs under their control.
Water Grid_EN 230561.jpg

Even more interesting was the Water Volume of a Reservoir that shows the current storage volume as of 20 January. Not looking good for us.
Screen Shot 01-30-20 at 08.34 AM.JPG

There's also another page called the Weekly Water Situation. Even though it says weekly, the last report was as of 17 January. Lots of pretty graphs in the situation report. The one that caught my eye was this one that lists water volume as of the 17th at 88.29 Million Cubic Meters (MCM). If I'm reading the chart correctly the target for this month was 240 MCM, but at 88 MCM that puts us in the Severe Water Shortage Warning band.

The weekly water situation report as of 31 January has been posted on the EW site (link). In the week since their last update the reservoirs are down about 6 million cubic meters. Assuming the trend is linear that means we have about seven weeks before we hit the minimum storage volume of 31 MCM.

Hopefully the rains will come and the reservoirs refill before I come over in July.

When I was in Buriram last August the farmers I spoke to were complaining how dry the wet season was. Hopefully 2020 will be back to normal.
