Actually now living in one of aforementioned locales, I can speak to this one:
Possibilities include, I suppose, “Reduced flow for water conservation? One of the most common substances in the universe aside, you live on a garden world with over 70% hydrographic coverage‽ How in the name of the seventy sloppy-ass devils¹ of incompetence do you have a shortage of water?”
(Ongoing conversations may touch upon handy natural phenomena like evaporation and advanced space-magic technology like pipes, aqueducts, and canals.)
I present an overheard half of a conversation:
“Look, we have aqueducts. All over the state. Been building ‘em basically nonstop since we acquired title—“
“This is on top of all the water reclamation efforts. It’s not needed all the time, but when you need it, you don’t want to reengineer the entire distribution system on the fly—“
“Reservoirs are not the problem. Not everyone has weather-control satellites in place from day one, you know. There’s this phenomenon called drought.”
“Yes, we know about desalination. We’ll be on that just as soon as we have the cheap power at sufficient scale. This regulation isn’t meant to be permanent—“
“Yes, our local ecology interface matrix is grossly unbalanced. We know that. This is where we made the mistakes that taught us that, in fact.”
“Now you’re getting closer. The property rights schema for the first waves of development were misaligned to the water resources actually available—“
“We do indeed put the perverse in incentive. I’m glad you find so much amusement in our misfortune. Can we monetize that sufficiently to buy the paddles to get back down the creek? No? Then maybe—“
“Your gnostic overlay is quite right. That is a disgusting metaphor. Unfortunately it’s also appropriate, since we didn’t get rationality handed to us on a palladium platter. Welcome to Earth.”
