Desalination is the process of removing dissolved salts and minerals from saline water. Desalination plants are used around the world to supply fresh water for human use, including for irrigation, domestic and industrial uses.
The cost to build a desalination plant varies depending on the size and technology used. A typical plant can use reverse osmosis or multi-stage flash distillation processes to produce potable water from seawater or brackish water sources at a cost of about $0.50 per cubic meter (1,000 liters).
The following is a list of factors that contribute to the cost of building a desalination plant:
Desalination Plant Size – The size of the plant will determine how much water it can produce in a given period of time. The larger the plant, the more expensive it will be to build but also more efficient because there will be less labor required to operate it. Smaller plants may require more frequent maintenance but are easier to operate by fewer people.
Cost to build a desalination plant
The cost of desalination varies widely depending on the technology used and the capacity of the plant. In 2020, the cost of producing one cubic meter (m3) of water from desalination is estimated at US $0.30 to US $0.60 for low-cost technologies, such as multi-stage flash distillation and thermal distillation, and at US $0.90 to US $1.30 for reverse osmosis technologies. This represents a 15% to 35% increase over 2019 costs due to higher raw material and energy prices

In 2022, the cost of producing one cubic meter (m3) of water from desalination is estimated at US $0.30 to US $0.60 for low-cost technologies, such as multi-stage flash distillation and thermal distillation, and at US $0.90 to US $1.30 for reverse osmosis technologies
desalination cost per m3
Desalination costs are expected to reach $17.5 billion by 2022, according to a recent report by GlobalData. The increase in demand for desalinated water is driven by two factors — climate change and population growth.
Desalination costs have been steadily declining over the last decade, but they are projected to remain high in 2022 at $0.75-$1 per cubic meter (m3).
The desalination cost is the cost of producing fresh water from seawater or brackish water. It’s used when there is no other source of freshwater available. Desalination plants are often located near coasts where fresh water supplies are low or zero, such as in desert areas.
Desalination plants can be powered by fossil fuels or renewable energy sources like solar panels or wind turbines. The most common type of power source is natural gas because it’s cheap and easy to find worldwide. But burning more fossil fuels will add more carbon dioxide (CO2) emissions into the atmosphere, which contribute to global warming and climate change

Why don’t those with the financial means build for the future. People all over the world feel the impact of climate change and if we do not do anything future generations will suffer.
