Desalinated Water In Australia

The consumption of water has been increasing in the last few decades. Most of the demand is caused by agricultural activities (BBC Features). Water needed for industrial purposes also drives up the demand. The world can learn about ways of conserving water from the countries that have initiated the measures and have become successful at it. Australia is considered as the most successful so far. Recycling, desalination, and harvesting rainwater are some of the solutions that can be applied to handle water shortages and create

Around the world people are suffering from the problem of having a safe and clean water, there are more than 633 million people lack access to safe water. Remote countries in Africa are mostly the victim of having unsanitary water sources.

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

Water is the most relied upon resource on earth and if it disappeared life could not and would not exist on this planet. So if one of our main sources of water in South Australia, The Murray Darling-Basin, becomes unusable then we would need to find the problem and do everything possible to stop it or counteract it. This report investigates on salinity in the Murray Darling-Basin, using the issue question “Is there enough being done to counteract the effects of salinity in the Murray?” as the focus. Salinity is a key significant environmental challenge which the Murray faces and if left unmanaged it could cause serious implications for water quality, plant growth, biodiversity, land productivity, infrastructure and could lead to a loss of

The issue of building desalination plants has been a hot topic of Californians in the past couple decades because researchers knew that our available surface and groundwater supplies are becoming scarce. This problem is important because California is home to a large population of people as well as extensive agricultural and industrial productions that need vast amounts of water. With the reduction in available ground and fresh water brings other problems that need to be addressed. Many farmers are having to impose stricter management policies in regards to how they use the water the pay so much for. Crops sensitive to the amount of water they receive or do not receive can be destroyed in a short amount of time if neglected of water. With the amount of fresh water accumulated by both snow melt of California’s mountains as well as ground water retrieved from wells and pumps being depleted faster than we can recharge those sources, farmers face further impacts. An article by Robert Glennon, “Unquenchable: Americas water crisis and what to do about it” says “In the summer of 2009, California is facing mandatory water rationing. Many farmers may be entirely cut off, costing the economy more than $1 billion and putting more

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

The first stage involves the removal of solid and liquid particles through filtration. Sydney Water mainly uses ferric chloride to prevent the recurrence of murky water. They also use small amounts of long chain polymers (polyelectrolyte) as a secondary coagulant. It is then followed by the inactivation of microorganisms; to which all monitored filtering plants uses a strong oxidant for disinfection (in Sydney Water, chlorine is used). The last stage involves the addition of fluoride to the water to fulfil the requirements of the Fluoridation of Public Water Supplies Act 1957. This, along with the added lime and carbon dioxide, reduces the corrosivity of

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

The aim of this report is to evaluate the proposals to increase water on the Gold Coast of these two types of water storage. These would be building a new dam or building a new desalination plant to find out their environmental and social impacts for the Gold Coast and its community.

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

Water. Well what is this common liquid that is compulsory and necessary for everyone to drink? Water is a transparent, thin liquid that has nutrients in it and has to be consumed. This transparent liquid can be used for multiple uses and it can never run out . Do u have to drink it ? Water is compulsory as our brains is 70% water and our body 60% water so we cannot function without it. The transparent liquid helps us be hydrated and balances your body fluids. So as you can see this liquid pretty important. In some countries, people are lucky as they can access water within seconds with a tap, but unfortunately in other countries it is harder to access clean,fresh water. Throughout this report I will be showing the differences between two

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

The water-energy tradeoff with desalination is apparent than any other options, given its energy intensity. Table 5.5 compiled some indicators to illustrate the resource features in provinces with desalination capacity. The majority of the present capacity is located in the most water and energy stressed provinces along the east coast. Desalination might be pursuable in some remote southern island, where freshwater availability has posed a constraint on basic human need. But it is still debatable whether large-scale desalination is a good choice for the water deficient north. From the nexus perspective, investing in more desalination projects in water-energy stressed areas could worsen their power shortage by adding more demand.
