Depleting the ocean of water? Ok, now you go get to sit next to the Senator that was concerned Guam was going to tip over.

You do understand that water desalinization is not mystery science. It is done today. Not sure why you keep arguing with a simple solution provided.

The new Cali pot law that Jerry Brown signed includes the Dept of Water Resources in it's oversight agencies.........I'll bet marijuana will be one of the first "unnecessary crops" to be cut off, in the next Calif drought....

California is getting some much needed rain this week, but more than two-thirds of the state is still in extreme drought conditions, and that has the state thinking about alternative ways of getting water.
On the coast in Carlsbad, Calif., construction workers are building what will be the largest seawater desalination plant in the Western Hemisphere. When finished in early 2016, it is expected to provide up to 50 million gallons of fresh drinkable water every day.
"That's enough water for 112,000 households here in the region," says Peter MacLaggan with Poseidon Resources, the developer of this $1 billion plant.
The process, MacLaggan explains, involves taking water from the Pacific Ocean, removing the silt, sand and "organics," then pressurizing the water through very fine membranes. The technical name is reverse osmosis. And the result? "Every 2 gallons of seawater that goes in, 1 gallon of high-quality drinking water comes out," he says.
Images of Folsom Lake, a reservoir in Northern California, show the severity of the state's drought. The photo at left, taken on July 20, 2011, show the lake at 97 percent of total capacity and 130 percent of its historical average for that date. The photo at right shows the lake on Jan. 16, 2014, when it was at 17 percent of capacity and 35 percent of its historical average.
THE TWO-WAY
California's Drought: A Shocking Photo And Other Updates
And MacLaggan says the best part is it's droughtproof.
"It's droughtproof because it's not dependent on snowpack in the Sierras, it's not dependent on rainfall here in San Diego," he says. "You're getting water from the Pacific Ocean."
The word "droughtproof" carries a lot of weight in California. That snowpack in the Sierra Nevada he's talking about is still less than half of what it should be for this time of year. Farmers, environmentalists and cities like nearby San Diego have been fighting over what little water there is.
"San Diego currently imports about 70 percent of its water," says Bob Yamada, the water resources manager at the San Diego County Water Authority.
Yamada says that's why the authority has agreed to buy water from the Carlsbad plant when it's finished — even though it costs twice as much as the water imported from Northern California and the Colorado River.
It's expensive "but it does provide you with the highest reliability," Yamada says. And he says people are willing to pay more for reliability. He also thinks that the difference in price between imported water and desalinated will shrink as more and more people vie for less and less water from rainfall and snowpack.
Desalination costs more because it takes a lot of energy to suck 100 million gallons of ocean water into a plant and pressurize it through little tubes. And that's where the opposition comes in.
"Well, on a macro level, we just think that there are less expensive, less environmentally damaging ways to increase our water supply," says Rick Wilson with Surfrider Foundation. The nonprofit environmental group opposes the Carlsbad project.
One reason, Wilson says, is that all of that energy use will contribute to global warming. More directly, he says, the intake pipe for the plant will suck in sea life, killing marine animals.
"And there's also the concern in some cases about the discharge from these plants," he says. Discharge is the extra salty leftover water that's pumped back into the ocean.
Those concerns have stalled plans for another desalination site farther up the coast, in Huntington Beach. Carlsbad though, has met all of the state's requirements. Still, Wilson says, money would be better spent on conservation and water recycling efforts.
Jeffrey Kightlinger, the general manager of the Metropolitan Water District of Southern California, says the district has invested in conservation and recycling, and it has helped, but the region still needs more water to meet demand. That's always been the case in arid California, but it's even more so now."

I think technically marijuana was never an acceptable crop to begin with lol. They've been raiding us as long as we've been growing. But I agree with you, just kind of a different point.

Hey doublejj, I have a lot of friends that go off shore tuna fishing for months at a time and they make all there own water from the sea with a little 12v system. 30L per hour would give more water than you need for any house and all it takes is one 12v battery. Its not an answer for a big city but it works really good for a boat.

Oh great...
Beautiful greenhouse(s) btw, seen some you've posted recently. Great work.

With the price of gas being so low, it might be cheaper just to truck in some of that water in from Texas.....lol

I mean, lots of us use rodi systems in our homes. Anyone can purify water on their own, small scale. It becomes expensive when you are trying to support an entire states potable water supply. Also, I bet that guy would hate to have to purify water like that everyday of his life lol. And the 12v battery waste....

So, is a small amount of sea life worth more than the comfort of millions of
It is not going to significantly affect the environment.
Seeding the clouds doesnt? Everything we do affects the environment. So you boil water, pump it inland, dump it on crops and the water evaporates or the runoff returns to the ocean.

It costs a lot to purify water too so lets just stop doing that... Oh wait, Michigan has taken the vanguard!!

If I had a solution I would be the head of the water resource board. There is no easy solution. We have been fighting over water out west for 200 years...
