What is the least expensive method of desalination?
For least expensive option, research solar stills. The daily volume is relatively small but they are generally passive systems with production dependent on daily solar exposure.
How much does desalination technology cost?
Based on Figure 7 below, a medium size 10 MGD SWRO plant would cost about $80 million to build and a large plant, such as the 35 MGD Carlsbad SWRO plant near San Diego, would be expected to cost $250 million.
Why California has no desalination?
Largely because of the energy required, the desalinated water that Southern California plants sell to local water authorities is the most expensive alternative to water brought in from the Colorado River and Northern California.
What stocks benefit from a water shortage?
Water stocks and ETFs to buy:
- Invesco Global Water ETF (PHO)
- First Trust Water ETF (FIW)
- Invesco S&P Global Water Index ETF (CGW)
- American Water Works Co. Inc. (AWK)
- York Water Co. (YORW)
- California Water Service Group (CWT)

How much does it cost to desalinate 1 gallon of water?
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 much did the Carlsbad desalination plant cost?
The desalination plant sits on about six acres of public utility zoned land next to NRG’s Encina Power Station on Agua Hedionda Lagoon in Carlsbad. It cost an estimated $537 million.
Is thermal desalination expensive?
We found that the LCOW for solar-driven thermal desalination ranges from $0.94–4.31 per m3 of freshwater, where the cost is affected mainly by the capital expenditure on the solar field and the operating expenditure of the desalination plant.
