Why is seawater desalination so expensive?

Why is seawater desalination so expensive?

Desalination, the process of removing salt from water, is expensive. One common desalination method, reverse osmosis, is expensive because it requires a great deal of electricity to push water through a filter. It’s also costly to treat the water to kill microbes and to replace the filters.

How much does it cost to desalinate sea water?

Desalinated water typically costs about $2,000 an acre foot — roughly the amount of water a family of five uses in a year. The cost is about double that of water obtained from building a new reservoir or recycling wastewater, according to a 2013 study from the state Department of Water Resources.

Is desalination expensive?

Seawater desalination is one of the most expensive sources of fresh water. The total costs of desalination, including the costs of planning, permitting, and concentrate management, are high, both in absolute terms and in comparison with the costs of other alternatives.

What are the advantages of using desalination to get fresh water?

The advantages of desalination plants

• They provide accessible drinking water.
• They help with habitat protection.
• They provide water to the agricultural industry.
• They consume a large amount of energy.
• High costs to build and operate.
• The environmental impact can be high.

What is a major disadvantage of desalination?

Desalination is not a perfected technology, and desalinated water can be harmful to human health as well. By-products of the chemicals used in desalination can get through into the “pure” water and endanger the people who drink it. Desalinated water can also be acidic to both pipes and digestive systems.
