A Case Study On Merredin Desalination

Each year, at least 7.8 trillion gallons of water are drawn up from the Ogalla Aquifer to irrigate the crops planted on the High Plains. These cros are the main food sourrce for our entire country. Tragically, irrigation is depleting the aquifer faster than it can replenish itself, and that is the problem. In fact, only the tiniest fraction of the water is ever replaced in the Ogallala Aquifer. If the water were ever fully depleted, the aquifer would need 6,000 years to refill naturally (Zwingle 83). The only way the Ogalla can be replenished is by water seeping down through the layers of soil until it reaches the aquifer. This water comes from the small amount of precipitation in the region, as well as from streams, reservoirs, canals, and irrigation (McGuire and Sharpe).

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

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.

If water amount collected increases or decreases, the catchment bottles can be changed and altered for size. As there is a range for the grain size of materials, there is some room of altering if the materials are for any reason, unavailable. The flexibility of the design allows for adaptation if required. The materials chosen are easily accessible, safe and hygienic once filter is cleaned. The small, yet efficient size of the design allows for portability, and can be used indoors in the case of a cyclone or unsuitable weather conditions. The device is designed with the local culture and geography in mind; primarily consisting of recyclable plastic bottles and grains from Vanuatu. As chemicals are excluded in the design, the materials are familiar appropriate, simple to use and will encourage the community to filter their water. The construction and maintenance can be easily taught to and performed by locals, both men and women. This design is flexible and can cater for different situations including material availability and

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

The current official population of Gold Coast City in June 2015 was about 556.000. And as the population grows, there is also more water needed as a water supplies. Beside the usage of drinking water, we need water for a lot more reasons like laundry and cleaning, toilets, showers and baths, faucets, irrigation and agriculture. If we don’t want to run out of water, there is need of more water sources building another dam in the Gold Coast Hinterland or building a new Desalination Plant in the northern area of the Gold Coast (SEQ Water, 2016).

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

Water Follies: Groundwater pumping and the fate of America’s fresh waters was about how Groundwater pumping has destroyed the water surfaces in the United States. Robert Glennon, the author of the book, wrote this book in a way that the reader would admire his exhaustive obsession for detailed research, in order to provide the most information to the reader. Even though the author wrote this book for history lovers and water and hydrology enthusiasts, most readers can get through the book without having the thought that this book is not for them.

The recent drought in Australia has raised the need for more efficient, sustainable management of water sources throughout urban areas in the ever-changing diverse Australian climate; with major objectives of reducing water pollution and

Many of the Basin’s natural resources are of high environmental value. It is one of the most significant agricultural areas in Australia, as it accounts for around $4.8 billion (39% of the national income derived from agricultural production) of Australia’s agricultural output and producing over one-third of Australia’s food supply, making it not only of crucial importance to the region, but to the entire nation. Also, more than 3 million people directly depend on the Basin’s water resources.

Water is a very essential component of living things on this world. It comprises three quarters of earth. We need fresh water for agriculture, drinking, medical and many other different purposes. But the renewable fresh water supply is less than 0.3% which is not enough [2]. It is really very hard to get fresh water for people who live near coastal areas to travel very long and get water for them. That is the reason why desalination came into existence where seawater is used as a source to produce potable water for use. The population grown bothered more for the demand of more fresh water. The fresh water resources like rivers, lakes are slowly getting lost or either getting salty [6]. There were several different approaches of desalinating the seawater to
