Construction of Concrete Water Storage Tank

[M&S]

build it.

Ramin, What percentage of your salary (you are obviously doing this research as part of your job description) are you going to send to the contributor(s) who plaster over your ineptitude? In a quick re-read of this thread you have posted your questions/replies like a college freshmen who is late on his homework. Too little data, too many vagaries, looking others to present the solution, and so on. You are basically asking this NG to better your resume' through no action of your own. If your company is well versed in the "traditional methods" of building such a tank than there should be SOME individuals within your organization who are capable of thinking outside the box and coming up with, or have heard of, some new and innovative ways to build such a tank. If there arent you should seek new employment as you are potentially on a sinking ship. With every reply you continually put another round in the chamber, point it at your foot, and pull the trigger. I am glad you are not on my payroll.

Hi Mark Actually I am not a college freshman, the fact is that I am not a civil engineer or anything like it. It's not a part of my job to do this kind of research, btu I have my own intentions doing it. If you know the answer to a question, it's your choice to tell it or not. But when you give such an answer to a question, it's just wasting yours and others time .

[Bob Morrison]

Your "intentions" would help us understand why you want to know this information. Then again, you could talk to an engineer who is well versed in water tank construction methods.

Posting this kind of open ended question to a newsgroup without any reasons as to why is bound to get you flamed (as you found out).

If you know the answer to a question, it's your choice to tell it or not.

umm ive done a tiny bit of research in this area

there are only 2 ways to have a decent cistern buy one = safe, fast and easy but you cant ship the dam things because they are HUGE

or make one with a food grade liner = pain in the

you can try all the concrete and coatings you want but that wont get you where you need to be and even dealing with a liner is old technology

the best way is to get a plastic tank that is made for drinking water they are expensive and you can get smaller ones at farm supply stores because farmers use them for stock you want a black abs one if it is exposed so bacteria wont grow

the reason i really dont suggest that you make your own there are some bad bacteria that are being found in these tanks studies are being done in parts of the usa not 3rd world countries finding that

just like the human papaloma virus is now found to cause cancer in women a lot of these things they are finding may cause serious illnesses and not just short term bowel problems.

so be careful

you will call and ask 40 pool centers and farm dealers trying to find a food grade liner and not one of them will have one clue about how to do this or get one.

the best way google cistern tank eventualy you will find there are a handful of gov sites and a handfull of dealers

drop $5000 on a 10000gal tank with a pump that can be partialy burried and build a kneewall out of cement block with a lid over it to protect it from light and damage

or better yet get two 5000gal tanks one for drinking and a non food grade one for toilets and have a way to connect them in last resort

and keep the dam thing clean so you dont endup with something bad in 20 years

I believe when you want to answer someone&#39;s question, you don&#39;t need to know his "intentions", you need to know his question. I think my question is clear and what I need is obvious: "the fastest method between different construction methods of such a tank". With a bit of logic you can understand that I want to know about different methods of cunstructing the tank in order to find out the fastest method. When you don&#39;t want or you are not able to answer somone&#39;s question, it&#39;s a complete waste of time while you know the meaning of his question but you just like to accuse him that your question is badly asked -instead of correctiong the question- , . Actually it&#39;s not only waste of time, it&#39;s a sick behaviour.

Thank you, I will consider this method. I haven&#39;t found any companies doing such projects with this method. I would be pleased if you could introduce any of of them (if you know any company working this way).

regards ramin

[Bob Morrison]

I very much doubt that you will find a 10,000-20,000 cubic meter tank constructed in this fashion.

You asked for the fastest method. One of the fastest (as mentioned by others) is to dig a hole and line it with with Hypalon or similar product. This is a common, fast and inexpensive method to build large volume water storage. You immediately rejected this advice because it didn&#39;t give the answer you wanted based on some criteria unknown to us.

If the solution must be a tank, then there is only steel or concrete. Neither method will be "fast". As I said earlier, a project of this size will take a least a year to construct. Just the infrastructure to fill and drain the tank is a major undertaking.

[<moo]

Call these people they are nice and know their stuff

This lady built one above ground many years ago I dont suggest this method because of health problems but lots of people have these things

other then plastic there are companies that build stainless steel tanks on your site. they are above ground units

also the studies I have read say do not rely on UV filters alone. They can not be your only purification method because they will fail to work when the bulbs need to be changed and you cant tell the bulb is about to fail

its like a bulb in your house lamp BUT UV needs to work

100% not like your house light that can slowly get dim and still provide light to read so you wont change it untill it fails to turn on. does that make sence heheh :o)

this means you need chemical, uv and mechanical filters

cleaning water in a small system is harder then in larger city size systems because the city just dumps chlorine in untill everything is dead and the CL keeps on working as it flows down your street to your house

in a small system you will have less then 100 feet to make sure everything is clean and cl takes time to work

Thank you, I will consider this method. I haven&#39;t found any companies doing such projects with this method. I would be pleased if you could introduce any of of them (if you know any company working this way).

Yes I believe that you are right.

As I mentioned before, I think this method may not be a healthy way to store water, as this tank is to be used to store drinkable water.

Yes, I think the solution should be a tank (as I mentioned in my original question). And you are right again, the project may take some time. But if the fastest method to construct a project this size takes years to construct, there is no other way. That&#39;s not my problem that the project may take to long, I just need to find the methods. Regards Ramin

Dan Deckert =E4=E6=D4=CA=E5 =C7=D3=CA:

ur impertanance. As Bob states;

because the only obvious solution is a tank. I suppose you could round up = a couple of million 1 gallon jugs & plumb them......har~har.....However, Bo= bs statement of, "a project of this size will take a least a year to constr= uct. Just the infrastructure to fill and drain the tank is a major underta= king." is a fairly qualified statement.

d of SERIOUSLY LOOKING at the advice given here. Unless you believe Captain= Kirk & Scotty are going to beam down here and make you some transparent al= uminum panels that can hold whales like in the movies.

a tank this size out of steel. Prices start @ $200.00/hr per man/hr plus a= ll expenses. Satisfaction guaranteed............... In essence get a damn h= int here and quit bitchin. Ie: Either shit or get off the Pot!

Without considering your language, that is an answer. I&#39;d be glad if I could find some of those companies...

[Bob Morrison]

Many jurisdictions here in the US use in the ground reservoirs to store drinking water. Some have covers and some don&#39;t. The City of Seattle is currently undertaking to cover these reservoirs and turn the covers into playgrounds and parks.

[Bobk207]

ho is late on his homework. Too little data, too many vagaries, looking ot= hers to present the solution, and so on. Mark may have posted this in HIS reply but I can assure that many

Well, I guess we&#39;ll just have to agree to disagree

you stated......

"I believe when you want to answer someone&#39;s question, you don&#39;t need to know his "intentions", you need to know his question. "

I disagree, in order to get a good answer to a complex situation one needs MORE information

"I think my question is clear and what I need is obvious"

Again I&#39;ll have to disagree...if your question was clear....you&#39;d have an answer by now.

The people who frequent this group have MANY YEARS of experience....the fact that you&#39;re getting similar replies points in a certain direction

The fact that that you "don&#39;t get it" why people reading your question "don&#39;t get it", is rather illuminating & food for thought. :)

good luck

cheers Bob

Bobk207 =E4=E6=D4=CA=E5 =C7=D3=CA:

Thanks Bob for your illustrative answer, But all the replies I&#39;ve got here are not similar, actually some people have answered my question (thank you all). It simply means that "they got it"...

At least 3 methods of constructing the tank are mentioned in this thread:

1) Wire Wound Prestressed Concrete 2) Stainless Steel 3) Glass Fused-to-Steel I think that Wire Wound Prestressed method should be a fast method proportional to its advantages. There may be faster and/or better methods, I&#39;d be glad if you could tell me about them (instead of nagging about my unclear question & "intentions")

regards Ramin

[Steve Barker]

Don&#39;t forget I mentioned the plastic lined hole in the ground.

[Bobk207]

Ramin-

I&#39;m sorry you consider my comments nagging....too bad, you would learn a lot if you took them to heart, as you said you&#39;re not an engineer but you are dabbling in that realm

And getting the right answer depends on asking the right question.

btw you forgot to list my very fast to construct suggestion.....a shot creted reservoir with a floating liner

cheers Bob

[Bobk207]

Ooops!

I missed the "stainless steel" option........SS for a 2.5 million gallon water tank.....I don&#39;t think that would really be very viable choice.

Oh, but don&#39;t remember reading if you required that the answers make any practical sense.

better questions get better answers :)

I&#39;m sorry I couldn&#39;t you give a better answer...too many unknowns

cheers Bob

[Ramin.Sh1]

Bobk207 =E4=E6=D4=CA=E5 =C7=D3=CA:

Okay Bob, I will consider what you&#39;ve told me. I will make my next questions as clear as I can. However, I&#39;m not a native English speaker. By the way, I am an enginner, just not a civil one. The method you have mentioned is the fastest method, I guess. But it will not solve my problem cause I need a tank.

regards Ramin

[Bobk207]

Ramin-

I could tell you were not a native English speaker but your English is very good (much better than MY second language).

I think that a fair amount of our disagreement on how to approach problem solving may be our different cultural point of views.

We Americans tend do be very straight forward & reveal a LOT of background information during the solution process. This method works very well for me on technical problems.

Other cultures (& I have worked with a few) do things differently. In my opinion these other techniques are much slower & do not (typically) find optimum solutions. Limiting information, limits the solution space.

but that&#39;s the way they do things, which, of course, is their right

By the way I am a mechanical engineer (design, analysis, 13 years in aerospace) who then spent 17 years in civil / structures research. I have years of design & project experience.

but when I go outside of my area of experience / education I&#39;m just a novice.

cheers Bob
