How We Priced the First Drop, and Why It Took a Century

The question Murcia will vote on next month — whether the first liter of household water carries a price — is being treated as a crisis of the moment, but it is the latest chapter in a very old ledger. For most of the last century, piped water in the wealthier world was priced as if it were effectively unlimited: a flat charge, a forgotten bill, a tap that ran because taps ran. That assumption survived precisely as long as the climate underwriting it did. As the mean anomaly climbed toward the +2.8°C the century now carries, and as reservoirs slipped across three continents, the flat charge quietly became a fiction — and cities began, one by one, to meter what they had once given. Murcia is late to a transition that has already reshaped half the water-stressed world. What its vote really settles is not whether water gets a price, but whether the city writes the floor beneath that price before scarcity writes it for them. Every corridor city eventually holds this vote. Few get to hold it early.
