In early July 2026 the town of Navojoa halted water service for a 16‑hour upgrade, marking the start of a series of short‑term cuts in Mexico. On 5 August 2026 the private utility Aguakan warned that maintenance on the Puerto Aventuras desalination plant would temporarily suspend water service in parts of Quintana Roo, urging residents to store potable water. The municipal government of Nezahualcóyotl also carried out a 72‑hour shutdown to drill a new well and close an existing one, amid reports of chronic shortages.

A broader regional report on 4 August highlighted similar measures in Puerto Rico, Bogotá and Santiago, underscoring a pattern of temporary water‑service interruptions.

Later that day, Puerto Rico’s governor announced a rotating 48‑hour water rationing plan affecting roughly 180,000 customers in San Juan and six neighboring municipalities. The move responded to a severe drought—the driest July in more than 120 years—and rapidly falling levels at the Carraízo reservoir, with water trucks prioritized for hospitals and elderly residents.

The same schedule saw Mexico’s Nezahualcóyotl 72‑hour cut proceed, a maintenance‑driven cut in Quintana Roo’s Puerto Aventuras plant, Bogotá’s utility planning multiple temporary suspensions on 5 August, and Santiago’s Aguas Andinas arranging valve‑change cuts in several communes. Together, these actions illustrate a coordinated wave of short‑term water supply disruptions across the region.
