This is really interesting -- the Turks in the 1990s (or perhaps it was even earlier) suggested a "Peace Pipeline" to distribute (and sell) water throughout the Middle East, including Israel, but no one (particularly the Syrians, through whose territory the pipeline would have gone) was interested per se.
The Turks also want to build a water pipeline to the Turkish zone of Cyprus. Water is an abundant resource in Turkey, and it is in short supply in the rapidly overpopulating Arab world, much of which is desert. Israel was interested in an undersea version of the pipeline, to supply water to its agriculturists, and to meet the terms of its 1994 treaty with Jordan.
Anyway, this new pipeline project is actually four pipelines in one -- crude oil, natural gas, water, and electricity (an electrical trunkline inside a pipeline). My view is that Gaza should be included in this, because a steady water supply in Gaza would pull Arabs ("Palestinians") out of the so-called West Bank, provided of course that they could get land of their own.
I expect this project will subsume the pipeline-to-Cyprus plan, such that both are completed. I also think that the Turks will find it difficult to engineer this (the pipelines are to be anchored to the seabed) without Israeli participation. Should be an interesting ten years, eh?
