The End of Abundance: Economic Solutions to Water Scarcity

Why pricing water correctly matters

February 3, 2017

Turn on the tap in most of the rich world and water arrives at a price so low that nobody thinks about it. That is a triumph of engineering and a failure of economics at the same time. A price that sits near zero tells every household and every farm the same thing: this stuff is practically free, so use as much as you like.

In a past of abundance that message was harmless. There was more clean water than we knew what to do with, and the job of a utility was simply to deliver it. Scarcity changes the job. Now the water we draw today is water that someone — a neighbour, a farmer downstream, a river, a future summer — cannot use tomorrow. A price near zero hides that trade-off completely.

A price is a message, not a punishment

People often hear “raise the price of water” as a threat to the poor or a cash grab by the utility. It is neither. A price is a message about scarcity, and the beauty of a good price is that it does the hard work of rationing quietly, continuously, and without a single regulation telling anyone when they may wash the car.

When water is cheap we conserve it out of virtue. When water is priced we conserve it out of self-interest — and self-interest never forgets.

What a scarcity price looks like

A price that reflects scarcity does not have to be a flat, higher bill. The version I argue for in The End of Abundance keeps the first block of water — enough for drinking, cooking and basic hygiene — cheap or free, and then lets the price climb for everything above it. The lawn, the second pool, the thirsty industrial process: those face the real cost of scarcity. Basic needs are protected; waste is not.

The result is quiet and undramatic, which is exactly the point. Demand bends down before a crisis arrives, so we never reach the week of emergency restrictions, brown lawns and angry headlines. The price did the rationing months earlier, one invoice at a time.

The alternative is worse

The alternative to pricing is command: odd-even watering days, bans, fines, inspectors and the slow erosion of trust that comes when rules feel arbitrary. Those tools can work in a true emergency, but they are a blunt substitute for a signal that everyone already understands. We do not ration bread or petrol with inspectors. We use prices. Water deserves the same respect — precisely because it matters more.
