Solutions to the Clean Water Shortage
Solution 1
The creation and development of desalination plants is a widely implemented solution to the clean water shortage. However, there are many reasons why it would be a good idea and some about why it would not.
Pros
Desalination would give us the clean water that many nations need. Many regions, particularly the Arabian peninsula, Australia, northern Africa, and South and Central Asia. It will also provide us with an extremely large source of water.
Cons
Desalination plants are expensive and is generally only affordable in middle or high income nations. The poorer countries do not have the funds to build and run desalination plants. The clean water shortage, however is shown more clearly in

Greenhouse gases will add to the already worrying problem of Earth’s increased temperature and the greenhouse effect. Also, in the long run, if desalination occurs at a high rate for the next few centuries, eventually the ocean would run dry. It will take a very long time, but it will. The ocean contains a vast amount of water, however it is not unlimited it and it will take centuries for the ocean to replenish and on top of that, it will upset the delicate balance within the biosphere.
Solution 2
Recycling is also a solution that has been implemented in some areas and is under discussion in many others. Recycling wastewater is the use of recycled and treated wastewater for agricultural, industrial and economical uses.
Pros There are many pros to recycling water, and one of the best is that it saves drinking water. Also, greywater-which is slightly used household water other than toilet water- has been proved to be beneficial to plants, more so than drinking water. Grey Water usually contains nitrogen or phosphorus, which are plant nutrients. The use of wastewater would further preserve the limited amount of clean drinking water. Also, reusing greywater keeps it out of the sewage system, which decreases the possibility that the greywater will end up in streams, lakes and ponds. In turn, it reduces the pollution in those areas which is good for the environment. Recycling wastewater
Recycled water is former wastewater that has gone through a process to remove contaminants so that it can be used for other purposes such as irrigation for crops and landscape (“Water Recycling and Reuse”). Another source of recycled water is gray water, which “is reusable wastewater from residential, commercial and industrial bathroom sinks, bath tub shower drains and clothes washing equipment drains” (“Water Recycling and Reuse”). The treatment process includes three steps, first any solids are removed from the water. Secondly, microorganisms are added to the water to eat dirt particles and as they get fatter, they’ll fall to the bottom of the tank, leaving cleaner water rising to the top. Lastly, water is
However, due to the long lasting drought in California we should heavily consider this method of producing clean water. In other parts of the world such as China, India, Australia, Spain and more they have been able to produce nearly fourteen billion gallons of drinking water through this process. The largest desalination plant in the world is located in Saudi Arabia and produces two hundred and seventy three million gallons of drinking water per day. If the United States is able to perfect this, it could fix the situation. Amanda Little does an excellent job of sharing a wide array of perspectives of desalination in her article “Can Desalination Counter The Drought”. For instance she describes the discusses the standpoint of the executive director of the California Coast keeper Alliance, Sara Aminzadeh, as she argues, “It’s just not a good option from a cost and energy standpoint.” She goes on to say, “Desalination may seem like a panacea, but it’s the worst deal out there.” Although this method may not be cost or energy efficient, this may be the only plausible method of producing clean water. As seen in Saudi Arabia this is an efficient form of creating clean water and due to the lack of resources, this may be California’s last
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”
There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is beginning to show its effects in first world countries, but is a current major problem facing lesser developed countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. In developed countries the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the vast majority of the population. Seventy one percent of
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.
Unfortunately, the water that is found in the ocean is not completely useable. The water has to undergo various processes before it can be safely used either commercially or for personal use. According to Science for a Changing World, “only 2.5% of Earth’s water is freshwater” and of that 2.5%, “only a little more than 1.2% of all freshwater is surface water.” That means that the rest of the Earth’s freshwater must be either in the form of glaciers and ice caps or ground-water; which would require some financial investment first to convert into potable water before individuals can use it. Moreover, the same idea applies to ocean water which would require desalination plants to convert the water. In Carlsbad, “a 1 billion [dollar desalination] plant is being built (...) [in] California to provide about seven percent of the drinking water needs for the San Diego region” (Bienkowski). With a cost of one billion dollars to cover approximately only seven percent of water needs in a region, it certainly not an efficient method to pursue, adding the fact that energy consumption would be costly through this production as
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

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
1. There are two main sources of fresh drinking water, ground water and surface water. Ground water originates from precipitations that usually fall in the form of snow or rain. While, the surface water is also originates from precipitate that reaches the land surface and is then recharged into rivers, wetlands and lakes. Although these systems are usually reliable, in desperate time of need, a more reliable source of water is needed. The desalination plant is extremely valuable and flexible because it does not depend on rainfall. Instead, the desalination plant is the only source that relies on seawater. Using seawater in the desalination plant helps meet the community’s water needs and secures the water needs in the future. While other sources of water, such as rainwater or water from dames are not reliable enough to strictly rely
As the worlds population grows, it is forced by circumstances that it has created to face the limitations of the worlds resources. Most people in the US have always been fortunate enough to have enough of whatever they wanted. When something they like breaks or wears out, they throw it away or buy a new one, and they often don’t even make an attempt to repair an item. They neglect basic maintenance until they damage their belongings beyond repair, and expect that they’ll always have enough. But some things are beyond their control, beyond there power or financial ability to replace or repair. The world’s drinking water supply is one of these without concern, without attention, without preventative maintenance and reclamation and
