Depends how much water costs; in the UK water is cheap compared to the cost of a plumber, but the UK is famously moist. I wouldn’t be surprised if plenty of more arid environments would find the cost going the other way, and preferring some combination of rainwater collection, greywater reuse, or non-water-based toilets. |
