MAFES: Brackish Water Facts - 01/27/13

The U.S. average cost for treating 1,000 liters of water is $1.10

All other things being equal, seawater is more expensive to treat than brackish groundwater due to the increased amount of TDS that have to be removed. However, seawater desalination plants sometimes have lower operating costs than inland desalination plants, largely because they can discharge concentrate streams directly to coastal water bodies. In addition, seawater desalination plants are frequently co-located with power plants to take advantage of common water intake and outfall structures and less expensive power.

Conversely, brackish water desalination facilities in inland areas may cost more to operate due to higher costs to dispose of concentration streams and higher energy costs.
