Australian cities are planning to build desalination plants to get more water ready to use instead of waiting for it to rain
The use of desalination plants is controversial. Two major concerns are:they use a lot of energy, which is supplied by coal-fired power plants. Apart from the pollution caused by these plants there are many who feel that they are not sustainable. That is, they cannot continue to operate without putting the environment and our future at risk.the water flowing back to the sea contains much more salt than normal sea water. It is also warmer. This can affect marine animals and plants that live near the desalination plant.
Desalination has very high energy requirements and since most countries with desalination plants do not have nuclear power, it results in the burning of lots of more coal. Additionally, the methods by which salt is removed from water create a resulting "salt-slurry" which is ejected as waste in to the original saltwater body. This salt-slurry makes the area around the desalination plant poisonous for the local sea-life.However, in almost every case, the positives of desalination outweigh these negatives.
There are a great number of techniques for desalinization of water, and many of them are quite primitive. They have been around for a long while. So there is no single answer for this question.
3 types of desalination are:Electrodialysis, Distillation and Reverse Osmosis (RO).
Illinois does not need desalination plants. It has plenty of fresh water from Lake Michigan.

The total area occupied by desalination plants on Earth is about 50,000 acres. This area includes various types of desalination facilities located in different regions around the world.

No they don't, Africans drink straight from the Nile river, which contains hundreds of wildlife species, including alligators, frogs, fungus and fish. They cannot afford a desalination plant, and desalinations plants clean salt out of the salt water.
all countries that have access to water
There are about 250 desalination plants currently operating in the USA and about 15,000 world wide. Most in the US are operating in Florida but dozens can be found in Texas and California.
Yes, desalination plants are generally expensive to build and operate due to the high costs associated with the technology and energy required to remove salt from seawater.
