Water tank cheapest technollogy 4

[Weldinspect]

Dear friends, I am looking for a project for the cheapest technollogy to store potable water tanks and I was thinking on corrugated galvanized technollogy but didn´t have much luck with Mr Google, only 1 company found yet.

Can any one advise if corrugated would be cheaper than welded onsite and give examples of american manufacturers please

Plastic is cheaper than metal.

Try fiberglass or PVC tanks or plastic water storage totes.

Thanks GeoEnvGuy, even if we are going up to 2000 cubic meters (528344 gallons)?

try searching for "bolted galvanised steel storage tanks"

Literally hundreds of suppliers all over the world up to several thousand cubic metres. But usually less than 1000 cubes

The agricultural suppliers are cheapest

e.g.

Thanks LitleInch, are this plain sheet bolted tanks cheaper than welded?

I was using corrugated galvanized water tanks on Google, now with bolted I gete more results thanks

Depends on whose doing the welding and how much you pay them...

But you can't weld galvanised so you have to bolt it.

Many sites seem to provide glass coated plates which bolt together for potable tanks in flat plates and again they can make the plates in the factory but then you can't weld them without destroying the coating.

It's just much quicker and simpler to bolt the plates together and you don't need specialised contractors, hence why farmers like them so much.

Thanks again, my question is in a general way (if welding should be done acording to standards) which is cheaper?

And yes, I know that if you would use galvanized welding is not the process, welded tanks should be treated on site

Hi Weldinspect, yes they have plastic and fiberglass water tanks of that size. From a quick google search an american supplier

Thanks GeoEnvGuy and sorry I didn´t mention it would be for an averseas proyect and they should be onsite asembled an din this site I didn´t find the size we need but up to 70,000 gallons and we need up to 528,344 gallons

Hi Weldinspect, there website states they could fabricate upto 1,000,000 gallons with fiberglass, I am sure overseas fiberglass tank suppliers can also fabricate larger sizes if you reach out to them. However transporting a tank that size may be challenging and you could be better off connecting smaller tanks in series or assembling a larger steel tank onsite.

Interested in why are you posting here, you quote a major manufacturer (

in your tagline who I would assume are more that capable of the design and construction of such a minor piece of equipment.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

 

[Weldinspect]

Dear Artisi, yes I´have supervised welded tank construction and that´s why I am looking for a cheaper solution thanks. Initially I thought corrugated galvanized would be the solution by using cheaper labor.

Wondering about the size of these tanks. Placement? Transportable? Serial coupled and produced smaller tanks cheaper than one large? Measurements? Climate? Permanent? This size would also suggest cheaper constructions if partly buried/supported by earth or frames, or even 'sack' material or concrete constructions.

By the way tried ship-building tankmakers?

 

[LittleInch]

Once you get the first course up the time is really about how you lift and support the following courses. The actual sealing of the tank plates is only a small part of the work.

Bolted tanks always have the highest leak potential.

Many bolted tanks now are actually glass epoxy lined and can't be welded easily. Flat plate is easier to coat and bend.

Dear @gerhardl

Placement? Above ground
Transportable? No
Serial coupled and produced smaller tanks cheaper than one large? Should be single ones in different locations
Measurements? 1000 and 2000 cubic meters
Climate? Tropical
Permanent? yes

Thank you

LitleInch:

Small leaks would be no problem and could be fixed, we are looking to lower the cost .... Thank you

Do you have concrete available locally?
might look into that...
2 designs are used in the US, pre-stressed and standard construction. The pre-stressed uses complex equipment, so I am not suggesting that, as that will drive the price way up.
but standard construction may be a solution, it uses more re-bar and concrete that the pre-stressed units.

Suggestion:

Quality requirements for the water will influence the construction.

Screw-bolted (demountable) metal frame constructions, inside (cheapest/corrugated/partly overlapping) mounted bolted metal or glass fiber screwed demontable plates, covered and inside sealed by flexible plastic sheet (adapted to tank form) All to be easily transported and erected at site. For potable water: Roof construction:tent formed fabric, reflecting 'silver' to cool, to hinder insects and animals, debris, to drain rainwater and withstand storms. All fenced in and/or protected. Maintenance, water tests and chemical treatment, and tank cleaning procedures.

Comment: Massiv constructed tanks are commercial more available and cheaper for somewhat smaller tanks than 1000 and 2000 gallons, and more easy to transport. Hence the idea of checking cost for lesser tanks in series. Perhaps also some mounted on top of each other? Several tanks in series will make it quite more simple to inspect and clean without shutting down the whole system.

Good luck!

Thanks, yes we do but maybe because we are a very sysmic country the designers choose not to use it

gerhardl:
Great idea thanks, smaller tanks may be cheaper to transport. We will check this
