Desalination plants.
Sorted.
Not really. Desalination is very demanding of energy; where is that going to come from? Furthermore water used for argiculture / horticulture is subject to straightforward evaporation losses, the more so in hot climates.
Desalinating water for it to evaporate to the atmosphere minutes or hours later doesn't seem to be a very intelligent solution.
