Saving water doesn’t make sense at all in a great many places where (clean) water is abundant, population is stagnant and infrastructure already exists. In other words, in many places water supply is mostly all about fixed costs and trouble with the water supply are not in any way related to consumer use of it in showers. (Agricultural use that leaves the water harder to clean up completely and an ageing population that flushes more and more drugs down toilets are more likely to crop up as issues, both unrelated to the amount of water that is used to shower.) In fact, disuse of water infrastructure can actually damage pipes and be very costly as opposed to just leaving the water running from time to time. (Just the logical consequence when the infrastructure – something that in the case of water can easily last half a century or more once built – is the main cost factor, not the water.) Obviously this is not universal and there are also a great many places where water really is a scarce resource.
