- From floods to droughts, CNBC Marathon explores the water crisis in the U.S.
Today, one out of three people don’t have access to safe drinking water. And that’s the result of many things, but one of them is that 96.5% of that water is found in our oceans. It’s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?
The western U.S. is experience a megadrought so severe, it is the driest two decades in at least 1,200 years. And no sector has felt the impact more than agriculture, which takes up about 70% of the world’s freshwater. With water resources becoming more scarce, several companies are working to improve irrigation efficiency and help sustain food production in a future where extreme climate may be more common.
Water is a cornerstone of economic activity, and when it runs low, communities face tough choices. The extreme drought conditions in the U.S. West are straining water resources and providing a fertile ground for wildfires. How will the West Coast face this climate challenge?
And 2020 was the busiest hurricane season on record. Flooding is one of a storm’s most devastating consequences. FEMA estimates one inch of flood water can cause up to $25,000 in damage. The U.S. began offering national flood insurance in 1968 but the program, called the NFIP, is now over $20 billion in debt. Private companies are starting to offer flood insurance as well. However, flood insurance is more complicated than it may appear. Watch the video to better understand how flood insurance works, and doesn’t work, in the U.S.

How To Fix The Water Crisis | CNBC Marathon
This speaks to a larger problem within the US. Everybody wants the benefits of publicly funded infrastructure, but nobody wants to pay for it, and nobody wants to pay for it while it is getting built and cannot be immediately used.
So our infrastructure ages and decays past the point of being unusable, then the same people complain about that too.
There's a joke that goes like:
"The problems of a private electric grid is so large it must be heavily regulated. The problems of a heavily regulated electric gtid is so large it must be nationalized. The problems of a nationalized grid are so large it must be privatized."
It's not true that nobody wants to pay for it. The boomers and the rich people that have all of the influence on legislation don't want to pay for it but largely the people that want to use the services want it and will be willing to pay for it.
tax cuts don't pay for anything but greed
As someone who has spent the past 20yrs or so working in a small city Gov,.. this is very very true. Everyone seems to want the BMW lifestyle for the Toyota Corolla price. But it dont work like that.
How do we pay for our military budget?
I live in a high humidity location. I have looked at building a solar powered dehumidifier pulling water from the air into a water tower. It would require adding minerals for drinkability, but could provide 100+ gallons of water daily.
Water solutions will end up being location specific as we get more and more efficient with water management.
So you would be a moisture farmer like Luke Skywalker!
I do that on a small scale !
My portable indoor air conditioner has condensation duct, and it drips out almost 10 litres of water each day.
I just collect that in a bucket & wash dishes with that water :-)
Be cautious with Airconditioner water as it may contain pathogens as it forms in a moist environment inside your home that reaches room temperature when the unit is off.
@@dasalekhya
Or use this water to take a shower...eh hem.
@@johna.4334 😀
Maybe time to treat water with respect and NOT let greedy corporations poison our waters.
Water is life .
There is plenty of water you just let it flow into the sea instead of recycling it back into the land. Controlled reservoirs could be built along side the rivers path to store water and help generate electricity. In areas of drought you could build underground drip irrigation systems to help regenerate the soil like they do in India. There’s nothing wrong with the amount of water that we have but how we manage it. I bet we waste more water by turning our faucets on full but never use that much water. It’s just a matter of common sense. If you are running out of water why would you let it run into the sea. How much is it going to cost you to recycle your river water? Well how much is it going to cost you if you don’t do it?
Because the fish need water to survive, so does the wildlife in the riparian areas.
They could also build massive subterranean cisterns
Flow into the sea lol, the sea isn't everywhere pal
Does fraking negatively impact water aquifer recharge? If so, how does this impact safe clean drinking water?
desalination comes together, when you have a lot of Renewable energy, and you use the desalination, to balance the production variations.
Creating water scarcity versus making water availability (sanatan ideology) will make huge difference and impact in lives around the globe.
Water desalination is incredibly cheap but has a high initial cost , private companies aren’t willing to pay the upfront costs to establish the facilities for a low return on investment
That’s what happens when you build a city in a literal desert. Why is Las Vegas there☠️
The gambled they would find water in the ground
It's claimed that Las Vegas recycles more of the water they consume than any other urban area.
States and local municipalities haven’t been protecting ground water assets for decades.
Next gen needs to pick up the fight.
We’re all just renting our current lives anyway.
Desalination costs about 1 cent per gallon. It should be the solution to all cities by the ocean.
A lot of water is used in total meaning it costs a lot, and what do you do with the brine?
1 cent per gallon? Sources?
that is highly dependent on the energy costs.
luckiely freshwater production is not time critical, so you could use surplus renewable energy.
Water wells for Africais in asl honesty the most impressive charitable well-drilling organization I've ever come across. I know the creator of the foundation personally and he's such a humble and hard-working guy who has no idea of the true positive impact he has had on so many villages, who deserve clean water as much as the rest of us do. The two things related to the water crisis that most surprise me are 1: the fact that there is so much water just beneath the feet of people lacking the resources to mine it, and 2: the impact that clean water given to villages really has. Diseases disappear, well-being and happiness is increased. I truly hope and pray that these types of charities continue to make clean water a universal resource. This year, Wwfa already drilled 57 wells so far, and every one of them are changing lives. It's so beautiful.
One easiest way to save water in southern California is to outlaw lawns, as Las Vegas has done.
Better use of water resources is essential. We need to be better at maintaining the natural systems which support a healthy and balanced water cycle to keep aquifers charged and local climates stable. We need to reverse the damage done by centuries of poor water and forest management too.
As long as we provide public fund subsidies to build or insure in either flood or fire prone areas, we will encourage continuing growth in them. As is the case with earthquake insurance, the premium cost must be risk based such that the insureds, not the public at large, pay the full cost of building in vulnerable areas. The government's job is to identify at risk locations and educate the public where the high risks are, allowing people to avoid purchasing homes and businesses in those locations. If they choose to purchase high risk properties, they should bear the risk and socialize it with unsubsidized private insurance.
It's the government's job? How about the government did nothing? Within a generation or two people would learn to avoid flood-prone areas (and Darwin would take care of those who is unable to learn).
@@JanBruunAndersen Did/can you read what I wrote? I said that the government should NOT provide funds that encourage people to build in flood prone areas. If you bother to read the last sentence, I specifically say that if people want to build in a flood plane they should do it at their OWN RISK. I didn't say that they government should protect property owners from their own stupidity; indeed, I don't think it should. Seems to me you are trying to pick an argument by not bothering to read what the other person is saying and leaping to unfounded conclusions based on your twisted confirmation bias.

La meilleure méthode d'irrigation est l'irrigation goutte à goutte.
Singapore 🇸🇬 is reprocessing waste water 💧 rather than using desalination.
Just did a research that California dumped most of its rain water into the ocean. Why they don’t collect it for use later?
Fresh water WILL BE the next oil of our generation, so abundant around us yet drinkable water is becoming increasingly so scarce, especially for developing nations.
Instead of oil pipelines, put in water pipelines from desalination plants to areas that need it. The excess salt can be used to create battery storage.
Only if you have enough lemons. Salt water kills soils.
Though there is some lithium that may, or may not be viable to extract from the concentrated brine.
All farmers in the world should have drip irrigation.
"All should" I bet you're popular at parties.
not all farmers need irrigation.
Is it possible to make use of the mountains of passive solar power for distilling?
Condensation of the humidity was practiced by the Incas of Peru. They built circular terraces which condensed the humidity as it swirled downward, getting colder, then condensing and therefore watering the crops. Also, circular terraces were used for collecting water in a basin at the bottom of the terrace, then having it flow through a canal for drinking water. Today, there are newer ways to condense humidity into water for agriculture and drinking water. The humidity cannot be seen, just like oxygen and CO2, but it is there for everyone. Growing desert grass 40” x 40” grids would anchor sand, gets watered by morning dew, could help trees to grow within it, and may eventually help rain to occur. Also, solar-powered refrigeration units could cool tanks of water that flows through pipes, causing drip irrigation by condensing humidity.
You are 100% correct
Only problem that would be nearly free process how are the Bill Gates going to make money???
Ya know that's really self centered thinking 😅😅😅
The problem here is that Peru has pretty high base humidity. Humidity is measured relative to its temprature and condensation happens when the air temprature drops and humidity would go above 100%. The air can't hold it so it becomes water.
According to a quick google search the capital of Peru, Lima, has an average 84% humidity. Compare this New Mexico with 44% and the problem becomes pretty clear.
Let's say you lower the temprature so the air can only hold half the water it previously could. In Peru that would bring you to 168% humidity so the air has to release that exes 68% as water. Which is about 40% of the water originally in the air.
In New Mexico you'd have 88% humidity and zero water.
Now these humidity levels are averages, the real kicker here is that during the driest seasons when you'd want to generate water the most condesantion is at it least usefull. Which is why outside of a few exceptions water from air solutions are generally not considered feasable.
use the brine to make salt?
So the best strategy is : aquifer fossil + best water management for irrigation + water cycle + collecting water to have more sources or to recharge them.
Could the brine be utilized in the production of lithium instead of it all being pumped back into the ocean?
wrong type of brine but it would be interesting if they could take it and create sea salt
Actually, there is the idea of brine mining. Extracting useful minerals from the brine. Lithium is one of them. Ocean water has 0.17 mg Lithium per liter. (So I guess more than 0.3 mg per liter in the brine?) Not sure at what price Lithium has to be to make the extraction profitable. On the other hand, sodium batteries now become a thing, and there is more than enough sodium in the brine.
@@mrm7058 so issue with this is that extracting lithium from salt water brine to the level of purity you need is at the current moment possible, but costs about 100x what it costs just to mine it elsewhere [now economies of scale could bring that down a bit, but its still going to be way more costly to do it that way so the price of lithium would have to jump EVEN more than it already has].
Same issue with Sodium for sodium batteries [which are still YEARS out from being commercially around in large amounts and have major issues themselves that will prevent them from being used in a lot of applications] given the fact you need super high purity sodium/lithium for these applications.
Most of the issue is simply that there is so much stuff in salt water brine, and that stuff really likes sticking to the other stuff, that getting the purity you need is very very hard [and also requires a lot of hydrogen and energy [which both tend to come from oil in pilot projects].
Will if you have a lithium mine nearby, you can use the brine instead of other water. Or did you mean to use the brine as a source for lithium
Come to Louisiana we have water for u 😂
Save water
canada has a lot of water , just take it , they let it run into the ocean
All coastal countries in the world should have desalination plants.
Most places even near coasts have groundwater. Water is nearly everywhere, the earth is so awesome. Just don't try to grow crops or live on the half of the land without cheap water underground. Water costs $0.001 a pound, vs $5.00 for steak or $1 for grain, its a millionth the cost yet still people whine. A person's water bill is about $0.1 a day, to shower, wash clothes, water lawn. We use 3000 pounds of water a month, 30,000 a year, we are so spoiled having to cut back a little like California to just 20,000 pounds a year.
@@amyself6678 agree totally, don't try and build huge cities in the middle of a goddamn desert, yes looking at you Arizona and Las Vegas, and then wonder why you have a water shortage. Ban grass for lawns in Southern California, and make them use desert plants and rocks for landscape, I know Vegas is already doing that to every place except parks, golf courses and I think one other location, all residential has to use desert-friendly species.
@@davidstufflebean3285 ... Even in Vegas our tech is so wonderful water is just $1 for 100 gallons so 800 pounds. Anything else 800 pounds is $1000 dollars.... If use 80 pounds a day for shower and washing it's a dime... The dirty secret is cities overcharge for water past the wholesale rate to gouge to pay for other city stuff like parks and police. Even water trucks from say Columbia river in Oregon would be about $2 for 100 gallons, which ain't awful.... God put so much darn water yet still we complain when it's not massively cheap.... For house electricity is $200 a month, water $20, this is shockingly cheap ..... It shows how people will complain about everything... I expect people to start complaining about the air, how it should be even free-er ..... Ha
to the extant, they build enough renewable energy so they have excess to balance.
Nova Scotia gets rain between 43 and 78 inches a year . Many homes collect rain water in their cisterns for everyday use. A desalinization plant is not required there. Broad generalities are not the answer.
Capture the rain , and allow it to replenish the aquafer . Build swales on hilly terrain . Slow down water on hills and valley streams to promote absorption of groundwater . Build water retention dams. Pipe excess water to a dry area. Protect the soil with mulch to prevent evaporation of soil moisture and provide compost.
What happens if you put brine inn a desert and let the sunn evaporate it? Culld we colect the salt inn dry form and have a easyer way of storing it?'
the issue is you would still have to find a use for it or otherwise you just get mountiants of it piling up. There is not that much demand for sea salt and the minerals inside of it are not worth enough to try and extract them.
Reduced snowfall in the Colorado mountains?? There’s hundreds of miles of snow packed several feet deep as far as I can see. I fly over it all the time as flight crew.
One good snow doesn’t change the overall trend
Is the brine safe to ingest? Can it be utilized in food production, preservation or preparation without causing adverse health outcomes?
it is seawater. just with less water.
@@MusikCassette Continuing to put brine back in the water with increasing concentrations of salt is damaging to the ocean's ecosystem and marine life. Think of the Dead Sea. A body of water can have so much salt that nothing can eventually live there. This is not an immediate concern for the ocean as the water is moving and other bodies of water and rain continue to flow into it. However there are those who are dumping more things into it in addition to the oil spills and other things that continue to find the ocean and subsequently our food and water. An ounce of prevention is still worth a pound of cure. It would be prudent to be proactive about preventative measures before the issue can become critical.
The Feds closed 550 dams so far in the USA each one would have provided a few communities with all the water they could use....
I'm for desalination as one type of solution to the water crisis, let's keep the research on it and at the same time let's find other technology.
What to do with the brine?
Since the water crisis is not due to lack of desalination, desalination does not solve the problem.
@@kieranh2005 Well, brine is nowhere near as harmful as nuclear waste. Brine is just the byproduct of the filtration system. It's created by the rejection from the membrane so this brine has always been in the ocean water the only difference is its concentration. there are several options to deal with it, like taking and distributing the brine at different locations within a huge area of the ocean. We could then monitor its effects, but there are at least other 10 solutions. This is why I think that more research is needed.
@@dfinma I don't think that you understand, there is a lack of potable water which is the issue and desalination is only one solution. or what is the problem from your point of view?
When a lot of these Desalination Plants are being built, they have an explicit need for the purified water produced from the split stream with RO Water Technology. This also produce a reject stream that is difficult to permeate a hyper membrane. There isn’t always a plan in exact for a separate industrial entity to utilize all the brine reject. For seawater application it’s called Brine because of the salt concentration doubling up to at least four times depending on % recovery of water set forth in process. In other normal application where it’s not Saltwater such as Brackish or less TDS salt water it’s easier to use that reject water for other purposes. Seawater by its salinity present a different problem as it’s quite salty. In many places the Brine produced is used by another different industry as a joint venture next to the water plant property utilizing the brine to make other salt products.
Depending on the size of these Seawater RO Plants there are sometime limitations on being able to use as much brine that is produced in their processes. Sometimes there just aren’t any other industrial players willing to build a facility next door to refine or reprocess the brine waste. I don’t know why exactly the financial aspect why not. From seawater brine there are different salts and compounds that can be refined so it isn’t exactly not useful. Lithium for example is in seawater, more in concentrated brine, but it’s still far less mg/l than what can be extracted from an actual land mine. They just need viable industries that can utilize all the brine for other products and it be less of an environmental issue as to how to properly dispose of the reject Brine. At best what many these Desalination Plants do is to run a pipeline out several miles back out to sea and pipe them brine there so it can be dissolved back into the ocean in a wide area. It does have an impact on the immediate local area to which that brine is piped. But that’s why at best most plants if that brine can’t be used by another industry they pump that brine miles back out into the ocean. That vs piping it into the local marina and estuary areas or just off the beach. Still, until there are real complete solutions as to what to do with all the brine, we’ll all keep discussing how to solve the issue.
Your title indicated a solution but you talked about problems
Two water pipes, one for salty and one for fresh water. Toilets and showers saltwater. One pipe for freshwater to drink and for crops/gardens.Better infrastructure.
That is done in other countries. Wish we did that here.
Why not extract salt from the brine and make industrial salt batteries, whereby you would not only eliminate the waste product but turn it into extra profit
Plant mangroves, I provide!
Is anyone else hearing- farming in a desert is very difficult.

Here’s an idea. Stop moving to deserts

Ban grass lawns! Every pre-teen and teenage boy will praise us for generations to come for ending the dreaded summer mowing job!
they could grow less water intensive crops in warm climates or do it in temperate climates instead.
use less pesticides and plant wildflowers so the pollinators thrive.
we may need to learn how to manage pests or use indoor farms.
the government should force insurance companies to inform potential buyers of flooding history, risks and other dangers.
how come people don't build higher or watertight homes on low lands with a history of flooding?
Every house beign sold should have a hazards report. Basically a report that shows how likely a natural disaster will occur to that area.
It is not the Farmers who are using too much water. They are growing our food. It is the too big homes for two people that is wasteing our water. I'm sorry to be so to the point. But it is the truth. Our farmers are not wasteing the average population is abusing the system. How much square footage of housing does any one person need. I lived in a car for three years. I'm still here.

Anyone think of evaporating the high saline water the salt is a commodity after all it is natural sea salt with minerals. Who knows someone could finally unseat that dastardly Morton girl .
Oh here is a thought, how about we stop wastng and poluting what we have. Who knows we may not have this problem now if we had hmmm?
Could the brine be utilized to help remove forever chemicals and medicines from the waste water in water treatment plants? Is there a process that may be undertaken to cause the chemicals to bond with the salt in the brine to help clean up the water and make it safer to drink?
I was going to ask these questions too. What's the chemical makeup of the Brine and how could we figure out how to put it to good use ? We need to stop looking at it as a "waste product" and start looking at it as an "potential opportunity".
@@jasonnugent963 If we've learned nothing else in recent years it's that the moves we've made to make things more disposable have created a waste problem of monumental proportions. The synthetic fibers and forever chemicals are killing us and destroying the environment. If we can find a way to recycle and reuse everything and extract the dangerous chemicals from our cleaners, solvents, pesticides, fertilizers products and environment then perhaps we can find a sustainable way forward.
@@brendahenderson683 I mean, OK. All that being true,.. this water was oroginally pulled from the ocean (we didnt mass produce it). All we did was extract the pure water and are now left with a concentrated brine. We have the ability to chemically analyze that Brine. We can ascertain what its made of. Why can’t we further break it down to usable raw materials ?… Humans solve much harder problems (such as sewage and polluted water reclamation). Saltwater brine seems like it should be easier.
@@jasonnugent963 In principle it does seem like it should be easier. As with many things it probably costs more somehow. In times past more costly options have been forgone for profits. It would seem that the brine could be useful for something. It definitely shouldn't be simply released back into to ocean.
@@brendahenderson683 I just did a Google search on “what can we do with desalination brine”,.. and it does indeed look like there are numerous research projects working on this.

I have learned in the school, that first approach against drought and soil erosion are windbrakes, and nobody use it anymore, and crying about problems!
Water shortage? Stop building in the desert!
Use the brine for salt to use for snow and ice removal...
Why not to use brine in salt plants?
the cost to actually extract any usable minerals is too high and there really isnt that much demand for sea salt to make it worth while.
Not any more we hang such a massive snow pack now
Yeah, if this documentary just came out, it didn't age behind the first viewing. "Oh, the scientists who are never right about anything predict that the droughts will just get worse over the years." Reality is it rained and snowed all winter long.
400 Litres per person per day is more than enough water to grow food for ten people.
There is no water shortage in the West, only a waste problem.
Why not produce salt with the brine?
yes, exactly, put it into the evaporation ponds, cover these ponds with plastic and the evaporation is fresh water, when condensed out of the humid air by cooling. The salt is a bonus, with significant value.
Add Lithium mining to the equation. Between using millions of gallons of water and the toxicity contamination- what could possibly go wrong
The desert SW needs to start acting like they live in a desert. Golf courses and growing alfalfa and cotton in the desert is the worst kind of folly and completely unsustainable.

Desalination requires HUGE amounts of energy.
UAE is the world’s leading desalinating country.

The truth is we can, the only issue is that large business interests don't want to do it, because it would allow people to recognize water for the grand commodity that it's always been...
The best way to do this is going back to distilling it, or boiling it, though using high frequency to generate magnetic resonance around a copper pipe , this creates an immediate reaction and uses a fraction of the energy needed, it can even come from sun light to power the apparatus...

Please Elaborate on this Magnetic Resonance method further.
@@ahmedshaharyarejaz9886 it's the same technology you would find in an induction cooktop...or furnace ...where there is a copper pipe that is heating and internal pipe it has to be steel, this is how the heat is generated, though it's not quite touching the copper... You just have to make a very well engineered system with one way valves so the water does not expand back through the cool area, continue this till you have steam and then distill or use it for any other type of propulsion...
Hope that helps...
No because a company would invest millions of dollars into building this facility only to find it’s just simply not profitable and that it’s not a sustainable business (at least in most areas). As a result, they’ve wasted time, money, and energy. It’s not always just “evil corporations” lmao
Why they don’t get salt from brine? It’s get more salt than sea water.
Why dont they dilute the brine with more ocean water and that will balance the salinity
your still increasing the salinity even doing that, and the amount of power required to do that would drive up the costs to unreasonable levels
The poles are covered in freshwater ice. If they are melting then why can't the brine be strategically deposited near the poles to compensate for the influx of newly melted freshwater?
the thing is: water has a very low value density. so Transporting it long ways is always a problem.
They should be using solar and wind as energy sources.
better yet, they should use surplus energy from those sources.
time for humans to clean their f mess
Why not use evaporation ponds for the brine? I’ve heard there is a market for salt.
Well the salt market is smaller, than the corrosponding watermarket. So you probably won't use all the brine for that.
Also strategically placed evaporation ponds could perhaps themself just produce fresh water. What goes up, must come down.
Imagine f.e. seawater evaporation in the Deathvalley

@@hurrdurrmurrgurr exactly i feel like these nuts farms for example in california (nuts are one of calis biggest agriculture export) use way to much water than necessary most of these farms dont even have drip irrigation meanwhile cali has been in a drought for the past 10 years.
Water bottle companies helps making the real value/cost of water visible. Only when the value is visible will people start to value water correctly and take steps to bring down costs and usage.
Instead of dumping all that water to the pacific ocean. You can reroute the snowpack water to central and southern California, Colorado River, Lake Mead. Start with those bodies of water to start with.
You failed to point out the latest type of desalination that has been developed just recently. It is easily scalable and leaves no salt brine behind to get rid of.
So at best it leaves behind the solid salt which still needs to be dealt with
Is it the one that takes the humid air from just above the surface of the ocean and condenses the water out of it?
@@kieranh2005 oh maybe? But in terms of scalability as energy efficiency? Reliability? May as well dig holes for lakes to fork next time it rains. It’s pretty much the same thing lol

Maybe plants may help us in desalination
The answer to the water crisis is build more, and bigger reservoirs, in strategic places.
There's no one answer, no cure-all, no panacea. Like most things in life there are many solutions and it's complicated, but it can be fixed if we start taking the issues seriously. There are a lot of tools we can use including desal, but there are also wasteful practices that we need to stop immediately like over-reliance on meat and the crops needed to make it, like alfalfa.
How to fix the water crisis:
Gee, I dunno, maybe stop boiling it all in power plants?
"Dilution is the solution". As the guy said, that is 19th century thinking for the handling of any sort of waste.
At the very least they have to get away from using a single outflow pipe at the bottom of the ocean. They should make an effort to dilute it right from the start. Ie mix the brine with ocean water to dilute it significantly.
As well, they seriously need to look at extracting useful resources from the brine before returning it to the ocean. There are lots of useful salts and metals needed by our industrial society.
CALIFORNIA needs to be put on a serious water budget. The other states in the Colorodo river have done much more to reduce use.
Agricultural sales are going to have to start including water cost, with a water trade element as well as the production cost. So production, farmer labor, fertizer, captial all cost a certain amount of money, on top of that growing 1 pound / ton of a product requires x units of water. The purchaser will have to provide those units of water as well as the money.
For the hydroponics farms, rather than going to industrial size, they need to be scaled to fit the needs of the local consumers. Create one of more hydroponics farms for the city. The idea is to make the food local, to reduce the environmental cost of shipping. Why ship tomatos or watermelons from california, when you can grow them locally. "Micro" Hydroponics farms can be well suited to remote locations where cost of fresh vegetables/fruit is prohibitive. Instead, grow them indoors locally.
The current historic water rights are going to have to be recalculated. Even if they keep the priority system, which I think should also be scrapped, the quantities of those allocations will have to be adjusted. ie they got X amount from the historic allocation. Well, it is known that those allocations were based on overly optimistic water flow values. So, take all of existing allocations, and grant each right a percentage based on current sustainable flows. Historic total allocation is x units.
Duh. If you see flood water in your house, it is time to jack the house up higher. ABOVE the flood line. In 1990, your house didn't flood historically. But climate has changed and now multiple floods are in your future. Jack that house up. The cost of jacking will be a lot less than replacing flood damage.
I know! Politicians who say nothing is happening and push back against ANY measure that would help.
The average person uses 100 gal a day of water!? Wow, not here for us. We're in the country on a well, so we're careful how much we pull out of the ground. We also collect rain water for use with our garden, livestock and washing cars/trucks. People need to look into more sustainability for sure.
Background music too loud
Real issues are not addressed,waste,wasteand greed.
We live in scary times 😢😢
Greenland was once green, before the climate change to become colder. I swear these people hate humanity.
I live in western ny.....were good over here....we have a few lakes by us 😂
Yeah but those lakes are gonna drown you in a few years based on projections.
Use the brine to make salt. Create a pool and let the brine dries and the remaining product is salt
Just a dumb question- WHY DOES FEMA NOT HAVE A INSURANCE COMPANY MAYBE IF PEOPLE PAY THEM THEY WONT HAVE TO WORRY AS MUCH ABOUT HELPING
The book Pluvicopia shows how the Red Sea Latent heat supplies sufficient water to flood the whole of the Arab Peninsula with all the water they could ever want. It has enough potential new aquifers to store enough water to control the sea level since the start of industrialization. Yes, that is 90 trillion tons of water, but we show how it is economically practical.
Why are fresh water sources drying up...???
You don't want unions doing the desalination or water filtration plants - those guys know how to purposefully screw up welds that need to be x-rayed & redone daily for a "gravy train" situation that extends the job costs & time to completion due to poor governmental oversight. Then there's also the inability to fire union members that can't seem to do the job "correctly". Nine mile two is a case in point - it was finally done YEARS past promised completion date & many hundreds of millions over budget! I know someone who worked there redoing welds as he actually takes pride in doing a job well done!
Instead of setting up desalination plants, why cant the ocean water be pumped into an new area which is artificially created like a big lake or pond covered with few inches of dead organic matter so that when it is filled by ocean water, the acquatic life is retained to some extent and the nature in its natural process of rejuvenation from the nearby tree leaves (acids) would neutralise these salts in due course of time.
This is very very low cost and may be highly sustaining in the long run.
Why don't they make salt with the brine
We should ship all the brine waste water to the Salton Sea.
I dont understand. Why not just dilute the brine before you send it back out to sea? So instead of taking in 2L and producing 1L fresh water, 1L Brine, you take in 4L and produce 1L fresh water and dilute the other 1L into the other 2L to make 3L of brine that is way less concentrated
