Desalination As A Last Resort

On March 27, 2014, Wade Graham of the San Francisco Chronicle reported “The Water Revolution California needs.” California is having a severe drought. Wade Graham tells his readers that California is in a serious water crisis. The state of California needs to make strict changes to how water is being distributed amongst farmers and residents. Before all of California’s ecological system is destroyed. Wade Graham believes that water should be priced higher; that way people aren’t wasting water. Water is a limited resource that should never be wasted, and is probably California’s most valuable resource. Unfortunately, many people waste water; instead of conserve water especially when we live in the state of California where we are subject to

“Israel now gets 55 percent of its domestic water from desalination, and that has helped to turn one of the world’s driest countries into the unlikeliest of water giants.” (Jacobsen) Desalination is not a new idea it has been around for along time as far back as Aristotle in the 4th century and re emerging again the 1800s. Desalination is probably not going to be the magic solution to California 's drought problem at least not completely after all even the world’s biggest desal plants are only supplemental. The plants tend to not make enough water to support an entire population. Israel 's desal plant provide enough water for 2.8 million people, but California 's population is five times as bigger than israel 's and our agricultural industry is about thirty two times bigger. It can also be twice as expensive as treating other water sources due to having to heat the water. And there is also the problem of what to do with the leftover water or brine. Apparently you can’t just dump it back into the ocean as it could cause death to the nearby sea creatures due to it being too salty.

The state of California remains lost as to what action to take with the drought. What is the proper solution to the current predicament residents of California are in? The answer to that question is an improved form of desalination and mandating the amount of water that farmer’s are available to and what crops they should be limited to. California coastline runs along eight hundred and forty miles of the Pacific Ocean. With this easy access to this water, desalination is the most plausible solution to the lack of water. It is a process in which salt is extracted from ocean water through a process called reverse osmosis. This process is incredibly expensive and power hungry but creating a

With the Pacific Ocean lining the California coast line some may ask why can’t sea water be filtered and used as a source of free water. This is actually an alternative that has been researched and even put into use in places such as the Netherlands, Aruba, the Middle East and even right here in the U.S. This process is called desalinating seawater. Saltwater in its pure form cannot be used for drinking water and is deadly to plants, however if it goes through the process of desalinating it can be used. With California desperate for water Carlsbad, California decided to construct a desalinating plant. An article on NBCNEWS website states that the plant can produce “50 million gallons of freshwater a day from the sea and pour it into a water system that serves 3.1 million people”

Desalination technology converts the tons of seawater that cover’s California’s coast into drinkable water. This process, though expensive and difficult, would provide California with an endless supply of water. The ocean is a huge part of the California lifestyle, and it could become a huge source of their water supply too. The Groundwater Replenishment System recycles water to be used again. It takes in about seventy million gallons of waste water a day and puts it through a cleaning and purifying process, that then makes this water safe enough to drink. Many people may not be comfortable with drinking recycled water, but this water could be put to use in landscaping and farming, adding seventy million extra gallons a day. The desalination process may be a bit far fetched for now, but using a water recycling program is completely feasible and would be a huge help in reducing California’s use of water. (only its not reducing, its just providing them with more water to use yknow? how should I phrase that?)

The water users of California have been asked to cut back water use whenever possible. This means shorter showers, drought resistant landscape, and low flow options for faucets and sprinklers. Farmer’s alike have been spotlighted to cut back on water use for it is calculated that they consume 80% of the state’s developed water supply (pacisnt). Although cutting back is a way to help conserve what is available, it is imperative that a new supply of fresh water be found before California overdrafts itself to no supply at all.

According to David Sedlak, we have made large progress in seawater desalination for the past 2 decades. The largest seawater desalination plant in the Western Hemisphere that is built north of San Diego uses half of the energy use than Santa Barbara 25 years ago. One reason why Sea Water is a good way to save more groundwater because we do not have a lot of water, but lots of oil. Also seawater desalination is not always good, there is a negative side. It is energy intensive; that means that it will cause a lot more climate change, but that is the only negative thing David Sadlak had mentioned about seawater desalination; but so far the new seawater desalination plant uses half the energy it used to. This would help California because it would lower the amount of water that is pumped from the ground, therefore, seawater desalination is a possible solution for conserving more

Since the discovery that desalination could provide humans in California with clean potable water from the ocean could be very effective, it

Desalination is basically the procedure of separating excess sodium chloride, minerals and impurities from sea and ocean water to make it usable for irrigation and human consumption. It has been touted to rid the world of its current water problems for nearly 5 decades now, during this period huge strides have been made in the desalination technology. These advances have made it possible to venture into desalination as the long term option to the water problem in many parts of the world. It is seen as long term since the ocean is not going anywhere anytime soon as compared to lakes and rivers that have been going dry seasonally. The state of California is not new to the water shortage problem; as stated above tit has been a witness to previous droughts. It is therefore time to consider a long term solution to this problem.

With the water crisis being seen around the world, even right here in the United States, we need to explore other options to supply fresh water to the residents. One State, in particular, that raises concern is the state of California. An alternative method to supply water to residents could be the process of desalination. Desalination is when fresh water is made by using either seawater or brackish and eliminating the minerals and salts as a way to make the water safe for human and agriculture uses ( Kesieme et al., 2013). In recent years, we have seen an increase the in the number of desalination plants around the United States (fig 1). However, is the process of desalination the answer for the water crisis going on in California? As a

If residents and corporations throughout the United States continue to frivolously waste water and refuse to make painless changes and upgrades around their homes, it will continue to increase in cost to people across the United States. For example, as a result of the water shortage crisis currently afflicting the southwestern United States, the city of San Diego, California, is currently constructing a desalination plant, located in Carlsbad, California. The idea of a desalination plant is to collect undrinkable saltwater from the ocean and, using reverse osmosis and other filtering techniques, remove the salt to produce clean, potable water (Barnett). However, there are many downsides to relying on desalination practices to provide for a city the size of San Diego. First and foremost, it is considerably more expensive to produce clean drinking water from saltwater as opposed to using regular surface water or groundwater. The act of filtering the water alone can be twice as expensive as traditional filtration methods. In addition, desalination plants consume much more energy than traditional treatment plants, mostly due to the fact that the filtration methods are much more involved. Desalination consumes twice as much power as recycled plants, and four times as much as pumping groundwater (Newell, Roohk and Reardon). For example, the Carlsbad plant alone will require the same amount of electricity as is used to power 125,000 homes in California. However, the biggest

A desalination plant is a possible alternative to California’s need of consumable water. There is a course cons against desalination mainly affecting the marine environment for leaving highly concentrated saline water behind through the process but we should not fear it as it is a long term solution we cannot toss aside. Kerry Cavanaugh from Los Angeles Times mentions, “2,000 an acre foot, compared to about $1,000 an acre foot for imported water” (par. 3). This means that production of water through this process is cost efficient and seems rather illogical to spend more money into producing water; instead of importing it from another major source. The process cost is not a major step forward, but the idea of reaching out to import water is rather absurd. California is an arid state; we are the ones responsible for turning it into a paradise. In order to maintain it that way a method to lower the cost of desalination can be propose as solution. The thought

The Pure Water project, a project that plans to construct three recycling plants to produce San Diego’s water supply, only requires $3.5 billion to get started – inexpensive in comparison to the amount of money it takes to import, partially purify, and desalinate water. An example of the ever-growing expense of imported water can be found in the article “Council unanimously approves purifying sewage into drinking water”, which was published to UT San Diego on November 18, 2014. In this informational article, author David Garrick states, “Councilman Scott Sherman said San Diego must fight back against sharply rising costs of imported water.” Potable water is the best way to combat the increasing prices of imported water. Rather than relying on water from the Colorado River – San Diego’s main supplier – existing water can be purified and reused. In the same article, it is also stated that, “In addition, recycling wastewater… would allow the city to avoid spending about $2.1 billion in upgrades needed at the Point Loma Wastewater Treatment Plant” (Garrick). As mentioned in the quotation, San Diego is already spending generous amounts of money on water. This can be remedied, however, with the implication of potable water, which costs significantly less. Another one of San Diego’s pricey water sources is desalination. Desalination is the high cost, high energy process of purifying salt water to make it drinkable. In the nonfiction article “OC Coastkeeper: San Diego Swindled By Desalination, Don’t Let OC Be Next”, published on February 3, 2016 to voiceofoc.org by author Ray Hiemstra, it is stated that, “San Diego is forced to pay for the most expensive water on the market whether they need it or not”, in reference to the desalination plant managed by

Desalination is one of the more popular options being considered to attempt to terminate the drought. Desalination is a process through which salt water is pumped from the ocean in to a treatment facility, and then the salt is extracted to make it possible to be used domestically. This is a long drawn out process, which involves seven different steps. The steps of desalination include the

Did you know that the Carlsbad Desalination Project by Poseidon will cost over $1 billion? This is one of the many reasons stated in the article, “California tries one solution to water problems -- treating seawater,” by The Sacramento Bee, on why the government should pull the plug on the Carlsbad Desalination Project. The project is expensive, dangerous, and unreliable, so we should heavily consider how toxic the aftermath of the project will be, before we make the poor decision to withdraw 100 million gallons of seawater from the ocean to meet California’s water needs.
