The Woman Who Mapped the First Corridor and Never Drank From It

She was born in 2041 on a stretch of coast that fed itself easily and assumed it always would, and she died last month at eighty-three having spent her working life proving that assumption wrong on behalf of everyone who came after. The engineer who surveyed and staked the first of the great desalination corridors — the template the Makran and the Sahel lines would later follow — belonged to the generation that watched the taps stop in the 2110s and decided, with a stubbornness that now looks like foresight, to build their way past thirst. She laid pipe for cities she never lived in, sized pumps for populations not yet born, and argued in a dozen ministries that made water was worth its cost because the alternative had no cost at all, only a queue. She herself, colleagues recall, drank rainwater from a barrel behind a house on high ground her whole life; she had outrun the scarcity she engineered against before the engineering began. Asked once whether she minded building for a thirst she did not share, she said she had never built for herself. "You lay the pipe," she told a young surveyor, "for the mouth you will never meet." The corridors she drew watered past a hundred and twenty million this year. The mouths she never met are drinking still.
