Yes true, but scientists have predicted this water shortage 30 years ago. Seems very lazy on the government's part
Converting wastewater to make it just clean enough to be put back into the bodies of water takes alot of time and money. And then converting that water into Fresh Water takes even more money and time. Now the government is about to waste so much more money than if they just planned ahead
Even as prices fall, desalinated water supplied to end-users still costs 1.5 to 4 times more than most conventional municipal freshwater sources like lakes, rivers and shallow wells:
Rivers / Lakes $0.10 — $0.50
Groundwater / Wells $0.30 — $1.00
Rainwater Harvesting $0.15 — $1.50
Wastewater Recycling $0.30 — $1.15
Seawater Desalination $0.50 — $2.50
Brackish Desalination $0.60 — $2.00
Cost Comparison — Desalination vs Alternative Water Sources
Besides improving traditional water supply infrastructure like dams and pipelines, regions today can consider alternative water production options:
Fog Harvesting $0.10 — $0.50
Atmospheric Water Generation $0.50 — $2.00
Cloud Seeding $0.10 — $5.00
Imported Icebergs $0.60 — $3.50
Current Price Range for Desalinated Water
The actual price of desalinated water entering distribution systems varies widely globally based on the above factors — ranging from $0.50 up to $2.50 per cubic meter:
- Middle East: Water from Saudi Arabia’s latest projects costs as low as $0.50/m3 thanks to cheap solar power and government fossil fuel subsidies.
- United States: Large inland brackish desalination plants in California and Texas supply water to cities like El Paso for $1–2/m3.
- Asia-Pacific: Singapore sells desalinated water to citizens at US$0.49/m3. Australian plants supply water to cities like Perth for around $1.75/m3.
- Europe: Prices in Spain range from $1.75-$2.50/m3 as exposure to oil prices and economic cycles add volatility.
Efforts to Reduce Desalination Prices
With global desalination capacity expected to nearly double again by 2030, intense focus continues on improving affordability by:
If R&D innovations continue lowering energy demands and equipment/operating costs keep improving, desalinated water prices could realistically approach $1 per cubic meter in the next decades — making it cost competitive with conventional freshwater across more geographies.
- Economies of scale: Bigger plants spread fixed costs over more water volume.
- Cheaper energy sources: Renewables and nuclear instead of fossil fuels.
- Lower lifecycle costs: Infrastructure and financing optimization.
- Next-gen technologies: Forward osmosis, biomimetics, capacitive deionization, etc.
- Government support: Subsidies, partnerships, supportive regulation.
- Carbon credits: Creating certified climate benefits to boost financing.
