Water tank, how big?

[jonnyscot]

I was planning in putting in a tank of around 1200ltr to feed the house supply, water is from the mains, but occasional water cuts we've seen for as long as 24 hours or more got me thinking to install a larger tank just to be on the safe side, however I've just returned from UK where I had to go due to the sudden passing of my father and my brother mentioned to consider not opting for too big a tank due to some water borne disease risks from largely unused water, I think he mentioned legionella although happy to be corrected on that one if I'm wrong, are there similar water borne diseases that should be considered when opting to install a larger water tank than may/may not be required

Thanks

We have 1500 l tank which I figure turns over every 3 days (3 people). While both the 'city' water and our bore pump water appears clear (no smells, etc.) I put a cap of bleach in the tank on a daily basis.

[IMHO]

Water usage varies... In our house of 4, we average 1,000L/day. We have 6,000L of storage (2x 3,000L), mains water is filtered via sand, carbon, resin and then activated carbon before going into the tanks, and both tanks get flushed and cleaned every 2-3 months. We have never had a problem with water quality.

Hey, Can anyone tell me the price range for such tanks please?

We were quoted 50k. Sorry, i don't know the size but it would apparently be a big tank. And that price includes labor and everything else required to install it and get water to the house (not the pump or the hole dug for the well...we already have that).

This sounds pricey to me, but i have nothing to compare with.

Some ball park figures would be great to give me an idea.

Thanks a lot

Thanks for the input Steve and IMHO, interesting point about inserting a few drops of bleach,

we will also have 4 occupants so maybe 1200ltr tank wouldn't be too far off the mark. Apologies, Wasn't thinking at the time of posting about emptying the tanks every so often so I'd imagine that'd solve any possible issues regarding water related diseases

My 3,000L stainless tanks cost me 18K each 3 years back. Have never seen a domestic sized tank for anything close to 50K - 3,000L ones are already > 2M high... As for plumbing, it's all just relatively cheap PVC pipes, fittings, valves and a float valve - maybe 1K baht all up..

If the 50K includes a large multi-stage whole house filter with auto-backwash, then yeah, 50K sounds about right including install, controller wiring and commissioning.

if you're serious about cleaning the tank regularly, consider 2x 600L tanks instead of 1x 1,200L, and add in another valve so you can keep water in one tank (and pump not running dry) while cleaning the other. A few more PVC valves and another float valve and you'll be able to set it up so you can pump the water from the full tank to the empty tank on cleaning day, so less water gets wasted, and everything continues working inside the house while you're doing the cleaning.

2x 3,000L tanks hold more water, have much more versatility, and cost 16K less

Edit: Oh I see this is Home Pro - forget them, their tank prices are ludicrous. Try cementhai, global house, watsadu or any side of the road vendor for proper prices.

Yes two tanks often makes more sense - I use two 1250 tanks here in Bangkok for high usage (a bit over one per day).

DMB tanks will not be cheap anywhere. But they are good.

[Water Buffalo]

Thanks for the info on prices. We will check out Watsadu - it's one of our usual places.

So how much water do you guys use anyway? Let's say family of 3/4, with a garden which will need watering from time to time.

Is a 5000L really necessary? Where we are there is usually water, but one the odd occasion we could be out for a day.

The stainless steel ones look nice, but is there any real disadvantage to the plastic ones? Anyone here had plastic with problems?

Thanks

[bankruatsteve]

Plastic OK if you keep out of direct sunlight. Ours is the blue kind and after 4 years (and daily dosage of bleach) has a bit of 'crusting' at the top but the rest of the tank free from algae and no other issues.

Thanks for the tip. Do steel tanks get the same problems with crusting? and do you have to add bleach daily too? (sorry, for the silly question - i am a complete newbie to this stuff)

[lopburi3]

SS tanks do not require bleach and only a yearly clean-out is normal (muck). Plastic in or out of sunlight will soon become an algae factory without chlorine but there is a sandstone plastic that does not allow sun to enter that has been reported as a good alternative to SS (especially cheap SS which can become pitted with minerals/salt).

I have normal extended family/maids to total about 7 people most days and normal water usage runs about 40 x 1,000 liters per month.

All the decent 18-8 stainless tanks, Diamond, Advance etc are within a few % price wise of each other - and you should expect to pay about 50% of MSRP.

Thanks for the very informative reply.

I will try to go for SS and maybe look into the sandstone plastic. With regards to SS and the mineral/salt problem, are you aware of any particular brand that is known to have good quality SS. Likewise, any brand that should be avoided?

Thanks again.

Just look for 18-8 stainless with TIS 989-2533 standard (ask for Mor Or Gor) - Advance brand with the red or blue sticker (not green), and Diamond are the two brands we've used w/out issue.

The stainless tanks are cheaper for sure and its my I understanding that predominantly they are used in the open towers, solar reflective and aesthetically pleasing.....

The grp type tanks are still cheap I think but many imported, western technology and often marked "food grade quality" which I scratch my head at.

These are more likely to be fitted into a roof as a pink,blue, white onion doesn't look great outside.

I am still trying to decide myself if a roof tank and pump would be better than an outside tank on a tower

[kamalabob2]

Top grade thicker stainless steel water tanks are available perhaps at a lower cost with free delivery and the option for professional installation from the "Go To Pump Shop" in your Province. Every Thailand Province has one or two "Water Pump shops" that do a serious business in sales and installation of water pumps, booster pumps, water filter systems and water storage tanks for for Municipal Buildings, Universities, multi story apartment buildings, student dormitories, and Hospitals large and small. In Buriram at the shop I bought and had installed seven 2000 liter water storage tanks from Diamond Brand Sandstone LLDPE tanks, the current everyday price for the 18-8 top grade Red Advanced Stainless Steel Water Tank is:

2000L 14000.-

3000L 19500.-

4000L 25500.-

5000L 32500.-

The current price for the Red label better grade Diamond Brand 18-8 Stainless Tanks are:

DIAMOND

2000L 17000.-

3000L 20500.-

4000L 25500.-

5000L 32500.-

The above prices should be easy to match in any province in Thailand. The above prices include free local delivery on a proper truck in Buriram from Buriram Builders Merchants Ruangsangthai Hardware which is located five minutes from the Buriram Ekachon Private Hospital on Highway 2074.

The photo attached is NOT from Ruangsangthai Hardware Store. The photo is a large village built rain water tank very near the Kap Choeng Thailand Immigration Office.

[cheeryble]

I need to install a tank soon.

I was actually thinking an old fashioned "ong" might look very well, and they are apparently only 1300 baht for a large one about 6ft high which probably holds a ton and a half or of water, maybe more, and should be fine for our little bungalow.

Are they good?

[Issangeorge]

Does anyone know anything about the Dos Eco Jazz tank? It seems pretty cheap and has a 15 year guarantee.

I built two small towers of concrete rings, approximately 3000 liters total capacity. First one (1000 liter) has a sand filter in the bottom DIY style, which then goes to the 2000 liter holding tank. Total cost less than 4000 baht. I can backwash and flush the system by readjusting valve positions. 3 years operation so far, no problems.

[NicoThailand]

Ok i think its a good price If you can build yourself.

Here are the type of tank you can actually buy.
To give you an example stainless steel tank of 2000 liters, the price of this product may be lower at 17,000 thb but it would consider at this price and delivery details and may be tank installation
because the profit margin on this type of product is very small.

Not sure why people aren't using these below at about 1500-2000 baht and must hold about 1500 litres, maybe more.

Anything wrong with them?.....this one's about 30 years old and works fine and I like the natural look of the surface it blends in the garden how much nicer than stainless or plastic.

So why pay extra $$$$ for something less satisfactory?

A form of madness?

Take a look inside it and tell us what you see

Good point IMHO.

But on reflection, wouldn't it have the same sort of stuff you get in a galvanised loft tank in England or a big concrete roof rank which all the condos have in Thailand?

(No dead pigeons......this tank does after all have a lid made of galvanised sheet as for gutters).

Really.....I'm intending so far to use on my upcoming CR mini des res and have to decide as I do the design.

(As there is a small cliff one side of the land I am also considering using multiple tanks his style in a line instead of a wall......perhaps offering a small prize to local art school class to paint as a project.....or possibly aboriginal pointillist style do myself for fun. Just need the little gaps between at the bottom filled a square foot or two. Perhaps less high than the one above which is the best part of six feet.....the shorter fatter style better suited about 4 feet high see below)

Good idea?

Useful comments.

Yes I knew they were concrete they're not actually at old fashioned they were introduced ca 1970.....but look quite natural when they're weathered and blackened off a bit.

They are a very good option, we bought 12 last year at 900 baht each. Best to get the standard half inch connection increased to one inch. They do not suffer from algae problems like plastic and as the outlet is about 6 inches off the bottom you do not get the sediment lying on the bottom.

Mount them on one metre concrete ring for convenience.
