How Desalination Stopped Being a Miracle and Became a Bill

The first corridors were built the way people build in a panic — fast, expensive, and without asking what they would cost to keep. In 2117, when the Andalusian summer emptied the reservoirs and the tanker convoys were being looted on the coast roads, the first great desalination lines went in as pure salvation. Water from the sea, endless and clean, pumped inland to cities that had forgotten thirst could be fatal. No one metered a miracle. Then the bills came. Desalination is not free water; it is water made of enormous energy, and energy, even fusion energy, is a thing that must be paid for, forever, by someone. Within five years the miracle had become an invoice, and the invoice a politics: who pays, who is billed by the liter, who is floored a free minimum and who is cut off at the cap. We metered the sea because we had to, and in metering it we discovered that scarcity, once engineered away, simply changes address — from the reservoir to the ledger. The corridors saved millions. They also taught a century that no salvation stays free, and that the true price of water is only ever the second thing you learn about it.
