The Corridor's First Full Season Ends, and the Word Everyone Uses Is 'Provisional'

NIAMEY / KARACHI — The desalination corridors that came online in the panic of early summer have now run a full season, and the verdict from the engineers who tend them is a single word repeated like a charm against hope: provisional. The Sahel spine and the Makran spine both held through the worst of the heat, delivering water to megacities that had rationed by the hour in June. Nobody who works the corridors will call that a triumph. "It held. I will say only that it held, and only for this season," said Tethys Hydrous Group engineer Farida Qadeer, who has said versions of this sentence all summer and refuses to upgrade it. The corridors depend on fusion power that depends on the winter build-out, on membranes that foul, on pumping stations strung across two thousand kilometers of hard country. Any one link can fail; this season, none did. Relief agencies logged a season without the standpipe riots that scarred last year. But the engineers keep the word provisional close, because the alternative — calling it solved — is the mistake that gets people killed the year the corridor finally blinks.
