How much do desalination plants cost to build?

The nonpartisan research group recently issued a lengthy report on the state of desalination in California. Beyond the environmental cost is the actual price tag: the plant in Carlsbad cost $1 billion to build, with a rough estimate of $50 million a year for the power to run it.

How expensive is the desalination process?

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.

How much freshwater can a desalination plant make?

The brackish and seawater desalination plants have the capacity to produce 245 million gallons of potable water per day.

Why are desalination plants 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 desalination cost per gallon?

While there are many variables related to the cost of desalinated water, Texas Water Development Board states a good rule of thumb is $1.10-2.40 per 1,000 gallons for brackish water and $2.46-4.30 per 1,000 gallons for seawater desalination.

How long does it take to build a desalination plant?

How long does it take to build a desalination plant? It takes up to two years from starting construction to finishing it. If we include the process from the very beginning – as in, gaining the permission to build and carrying out environmental impact research – it can be as long as three years.

Why is the desalination process 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. Researchers are hoping that improved membrane materials could make this process cheaper.

Are desalination plants cost effective?

MSF distillation plants produce about 60% of all desalinated water in the world, and the MSF process is considered to be the most cost-effective process for the production of fresh water from seawater in places where the cost of energy is relatively low, such as in the Arabian Gulf.
