Sea water desalination plants or sea water conversion techniques are special technology, which converts salty sea water into drinkable fresh water. Have ever wondered, how much it costs to construct these wonderful plants? Read on to discover more about the costs of building a modern sea water desalination plant.
Now, let us say that we are talking about constructing a modern sea water desalination plant. And the price can range from millions to even hundreds of millions! This wide range hinges on two main factors: the size of the plant, and the location in which it is built. A small plant, for example, will typically be cheaper than a large one. Where hasn’t been better, she says. If the plant is instead built where fresh water is truly in demand, it may charge more since locals want the access.
So, how do you estimate the cost of building a sea water desalination plant? When will require a significant investment, we need to consider a lot of crucial elements in order to determine how much it will cost us. These variables include the size of the plant, where it will be sited, what technology will be employed there and even the cost of the labor force and construction materials.
To do all of this experts study a feasibility study. This study calculates the upfront costs of building the facility, as well as the long-term operational and maintenance costs associated with it. It is defining our plan in terms of covering all the bases to ensure it can deliver potable water for the foreseeable future.
The kind of technology in use is another key factor. There are also various forms of desalination, like reverse osmosis and distillation, each with different price tags. Reverse osmosis passes salty water through a specialized filter that removes the salt, or distillation boils the water into vapor and cools it back into liquid, both leaving the salt behind. The technology selected can affect the total cost to construct and operate the plant.
In reverse osmosis, salty sea water is forced through a filter that only allows fresh water through, leaving the salt behind. This technique is more used for smaller plants as it is more economical. Distillation, on the other hand, treats the water to a steam bath of sorts, boiling the water into steam then cooling back into liquid form. This technique is usually better for larger plants, as it is able to accommodate more water at one time.
Constructing a sea water desalination plant is extremely costly, and the cost may vary due to multiple factors, such as its location and quantity of desirable fresh water. Where fresh water is scarce, constructing and running a desalination facility might be preferable to alternative sources of water — such as drilling for subterranean supplies or transporting water over long distances.
