Water as a hot commodity in the future?
(OP)
I've been hearing talk of water scarcity problems developing in the future. Even to the point that water will one day become a very valuable commodity. The fuzz claims that within 10 years, water will be in the same position as oil is now.
Any thoughts on that? Any ideas how it will affect our profession in the coming years?

RE: Water as a hot commodity in the future?
A 200 MW power plant near my house evaporates 15,000 gallons per minute. Today they're using high-quality river water. Many large power plants are looking at using lower quality water (like from oil & gas wells) instead because the cost and availibility of clean water is becoming prohibitive.
There is a lot of marginal-to-poor water available in the environment that is "waste" because clean water has always been pleantiful. In my research I found a lot of places where that paridgm is changing and people are trying to waste less and clean up marginal sources.
You won't see $70/bbl water any time soon, but $0.0025/gallon probably won't last much longer.

I don't think the US is there yet. Although the major river diversion projects (Colorado River?) in California comes close. Isn't that one of the reasons for the Hoover dam?
However, golf courses in both areas still water the grass. I guess the price of water has a ways to go yet.

I know that some filtration companies are having success in the water recycling market, Zenon is one example.
epoisses, that's a good idea except I'd rather not have bits of polar bear in my drinking water :)

Water as a hot commoditiy won't be a reality for a while yet.

Water allready is. Check the cooler in your grocery store. Lots of water in there, 10 years ago you had to find the water fountain in a grocery store to get a drink.
RE: Water as a hot commodity in the future?
good point, however that could also be due to the perception people have that bottled water is better than tap water.
RE: Water as a hot commodity in the future?
The question is potable water - that stuff is already quite valuable in certain parts of the world.
RE: Water as a hot commodity in the future?
It goes into unusable sources; the oceans through increased impermeable area (storm sewers) piped into the rivers into oceans. Water mining of aquifers (removing water more quickly then they can naturally recharge) is another draw-down of usable sources. Mexico City is actually sinking because the level of the underlying aquifer has dropped so much. Sure they could recharge naturally over hundreds/thousands of year, but I don't think the parabolic growth of our population will allow that. Additionally, human impact has affected natures ability to naturally filter and clean surface waters through destruction of wetlands and and contamination of soils and aquifers.
Water will indeed become very valuable and IMO belive more than one war will be fought over water.
RE: Water as a hot commodity in the future?
Thumb through a few of these
I think Mexico City is pretty representative of our impact and usage.
RE: Water as a hot commodity in the future?
Thank you for the link. Unfortunately, there are water shortages around the globe, and not every nation is as lucky as my nation.
That said, how much do you pay for water on your water bill?
For example, residential water prices:
western Canada is $0.003859/US gallon
western US is $0.0025 /US gallon
Using crude oil at $60/bbl, that is about $1.43 a US gallon. Oil is currently 370 times more expensive than water.

That aside, oil is a finite resource that will one day be depleted regardless of conservation efforts and an oil crisis is will occur at some point. It is simply how long it is rationed.
As Jabberwocky pointed out, water isn't going anywhere in our closed system. Poor management, localized over population, pollution, arrogance, and short-sidedness will be the sole cause of the blossoming water crisis.
RE: Water as a hot commodity in the future?
$0.0025 /US gallon!?!? Water at my last house was about $90 for 3000-4000gal, or about $0.0225 to $0.03 per gal. / Chicago Suburbs. That included "disposal" (sewer) charges of about $8/mo. I currently pay about $0.013/gal for water, and use a septic system / central illinois. It'd be great if water was 90% cheaper!
RE: Water as a hot commodity in the future?
RE: Water as a hot commodity in the future?
It seems that water is more expensive in Chicago.
However, I don't foresee water getting to $0.25 in the next 10 years. A 10 fold increase in water rates in 10 years would be a lot.

Some nations are rich in solar energy stored in the form of clean water. Others are not so lucky. So yes, there will be conflict over access to this resource in future.

"Many of us who are concerned about conserving water tend to focus on the water that’s going down the drain. We might install low flow toilets, front loading washers, and try to shorten our time in the shower, but as Fred Pearce demonstrates in his new book, “When The Rivers Run Dry,” we should be more worried about what we’re putting in our mouths. It’s food production around the world that’s leading us to an almost inevitable global water crisis. "
He has an interesting viewpoint; I'm sure the beef industry won't like it. Is water that goes into agriculture really so bad?

For my water usage, if my water was metered, I would pay 0.8pence per litre (£8 per cubic metre) which if I have done my conversion correctly is $0.053/ US gallon.
It seems we pay more for our water in the UK, as we do for our petrol.
RE: Water as a hot commodity in the future?
I can see why water is more expensive in the UK - the US has more water available per capita.
I don't know why the oil and beer is more expensive though.

On the plus side, we dont have euros yet, still good old fashioned pounds sterling.
I also believe our 'water of life' is cheaper elsewhere in the world even though it's made here. Water of life being Scotch Whisky.
RE: Water as a hot commodity in the future?
My bad. The UK is using pounds sterling, not euros.

Holy.. I hope it was a British Pint (closer to 20 oz) then! I can't speak for Detroit but most places in Florida aren't going to charge you more than 5 dollars for a (16oz) pint and places where it is actually sold frequently (Irish Pubs mostly) it's usually closer to 4.
RE: Water as a hot commodity in the future?
Imports are usually about $7 a pint (16 oz). Domestic about $6 a pint. Taxes included.

More new power plants are considering the use of air cooled condensers in lieu of water cooled condensers with their associated cooling towers - this saves an enormous evaporation loss of water, but hurts heat rate slightly. Noise levels are high as well.
Some large water users are being retired , to allow alternate use of their water . For example , the Mohave power plant in Nevada had used a coal-water slurry pipeline to ship the coal from mine-mouth to plant- its retirement will free up the water used in the slury plus the evap loss at the condenser .
In the long term, there is going to be a lot of teeth- gnashing related to the pollution of deep ground waters by the ongoing practice of injected toxic wastes in deep wells.

Microbrew beer on the other hand is a worthy drink. The Portland, Oregon, area has more beer choice per capita than anywhere else in the world. One could go out for a different draft beer, brewed within 200 miles, each night around here and probably go on for over a year without having to repeat anything. You'd periodically have to go back to certain places to get all of their seasonal brews. You couldn't do it at home with bottles though, many of the brew pubs don't bottle anything, it is only available on draft. Cheers.

Are you trying to say there are beer companies that show horses and purport to use them in manufacturing?

Although potable water scarcity isn't seen as an immediate casus belli of world magnitude, water suitability for human ingestion may be a present-day predicament in need of imaginative problem-solving by professionals in multiple disciplines.
It certainly is a combination of the chemistry of the solutes and their concentration that determines whether the water is polluted or not.
Even pristine rainwater may contain dissolved gases (on a weight basis): 10 ppm nitrogen, 50 ppm oxygen, 3,400 ppm carbon dioxide picked up from the atmosphere, to name just a few.
On the other hand, chemicals are supplemented on purpose, for example, sodium benzoate is often added as a preservative to canned fruit drinks in the amount of 1000 ppm.
The concentration (ppm) of minerals on samples taken from several French Alps natural spring water sources showed: Ca→78, Mg→24, Na→5, K→1.
The (US) Water Act of 1974 established the permissible maximum levels of mineral contaminants in community water systems for safe drinking. Among them, (ppm=mg/L):
As→0.05, Ba→1.0, Cd→0.01, Cr→0.05, Pb→0.05, Hg→0.002, Se→0.01, Ag→0.05, Na→160.
Do you know whether these limits have suffered any changes of late ?
I still remember Perrier's withdrawal of ~70 million bottles from store shelves and restaurants in 1990 because it was found they contained 15 ppb benzene, triple FDA's permitted maximum of 5 ppb. Any comment ?
RE: Water as a hot commodity in the future?
First and last time I tried that was in a bar in Chicago's north side, watching a five nations game (only five in those days). Dreadfull. Mind you it was about 8 in the morning!
RE: Water as a hot commodity in the future?
No, I was suggesting that hidden horses are used as the source of the product.... But only the big mass market stuff; micro brews on the other hand are actually beer.
The rebellious youngsters around here rebel by drinking PBR. With all the local brews available, Portland is also PBR's best market.
RE: Water as a hot commodity in the future?
Those Portland kids must be good kids, all the little b___rds around here smoke dope and drink hard liquor...with the occasional cheap brewsky when mommy and daddy's cash runs out.

RE: Water as a hot commodity in the future?
The regulations were written in such a way that it said the water shall be cleaned by x%. So, even though the water the plant was discharging was cleaner than what they were taking in, they actually had to mix the discharge with 'dirty' water to meet regulations.....
or something to that effect.

DRINKING water, however, is a problem even now in every major city. By what I see when I travel, I mean. I think a lot of dough will be in that industry VERY soon.
