After an unusually hot month of May, I've been thinking about Hong Kong's drinking water. I've never had to worry about water rationing, so I take it for granted there's water in the tap. That's only a recent luxury though, as Hong Kong struggled for many years to provide its residents with enough drinking water. I'm sure many readers will remember scenes like this.
