But it WOULD take less time to evaporate, a saving of resources.
But as far as localised problems you're concerned about, yes I agree
with you, it would need to be considered so it would impact least in
a
particular situation. But with problems there are solutions.

Did anyone see "The Inventors" show a few months back with the small
liquid purification unit that is being used by Rotary in an aid
program in Pakistan?

This unit could clean up any sort of water and make it potable. Using
this unit it would be possible to put sea water pipes directly into
Sydney households and have a salt collection service that runs just
like the garbage service does now. Dunno why someone hasn't come up
with that idea. Maybe tehy think that households would splash
seawater around outside.
