Eli5: why haven’t we started considering or implementing large scale desalinization in response to our water shortages?
In: 307
The economics of desalinization make it a challenge. Plants are incredibly expensive to build, take a lot time to build so in the time it takes to design, approve, build and get on-line the drought may be long gone. And because of the costs to build, the amount of energy needed to run, the ongoing maintenance/replacement of filters, salt disposal, etc. factors to deal with the costs for the water it produces are much higher.
