I remember once watching a Bert Haanstra documentary about how the biggest problem faced by civil engineers in The Netherlands was keeping the water out, not getting it in! In my final decade in the UK, I flew between Teesside and Amsterdam several times a year, and remember noting that everything visible from the North Sea coast to the runway at Schiphol was basically an enormous marsh.
Water scarcity has always been a fact of life in Southern California, but we seem to be getting into a pattern of drought years interspersed with deluge years, and of course there is no infrastructure for storing significant amounts of water. Mulholland designed his infrastructure approach (the California Aqueduct and so on) to take advantage of the fact that the Sierra Nevadas gradually discharge their snow pack into the system during the summer and fall months, which is a cycle that can't be relied on anymore. My impression is that the gains that can be made by reducing consumption per head have already been done (aerators in faucets, pushing low consumption toilets, laundry machines and dishwashers, cactus and gravel in your yard instead of grass, that sort of thing), and that the next step either has to involve reducing the population, or more and fundamentally different infrastructure (e.g. desalination of sea water, which brings its own challenges because of the amount of energy the process needs).
