Puerto Rico Imposes 48-Hour Rotating Water Rationing as Carraízo Reservoir Runs Dry
More than 500,000 people in Puerto Rico are subject to government-imposed water rationing after the island's driest July on record left the Carraízo reservoir critically depleted. BBC
The rationing scheme, administered by Puerto Rico's water utility Autoridad de Acueductos y Alcantarillados (PRASA), splits affected households into two groups. Each group has its water supply shut off for 48 hours on a rotating basis, leaving hundreds of thousands of residents going without running water for two days at a time. Seven regions served by the Carraízo reservoir are affected, encompassing 180,000 properties.
Governor Jenniffer González said the rationing was implemented due to weather conditions that have left the reservoir depleted, and that the decision was taken after carefully evaluating the current conditions of the Carraízo reservoir in conjunction with weather forecasts. The US Drought Monitor confirms that most of Puerto Rico is facing moderate to severe drought conditions, with 68% of the island under drought.
The immediate trigger is meteorological. But the structural conditions amplifying the crisis are man-made. PRASA loses roughly 65% of the water it produces as "lost or unbilled," much of it through leaks in ageing pipes. That figure means the utility is delivering barely a third of its output to paying customers before rationing even enters the equation. In a system already hemorrhaging more than half its supply, a drought of this severity compounds an existing infrastructure deficit rather than creating a novel problem.
Puerto Rico's Department of Consumer Affairs (DACO) has responded to the rationing by issuing Order 2026-003, which controls the prices of water sales and other essential products. Wholesale price lists effective August 7, 2026, have been published on DACO's website. Price controls of this kind typically aim to prevent speculative gouging during emergencies, though their enforcement and market effects depend on implementation details that remain to be tested under current conditions.
PRASA publishes current reservoir water levels on its official website, acueductospr.com, allowing residents and officials to track the island's storage capacity in real time.
The broader context here matters. Puerto Rico's water infrastructure has long operated under strain, and the 65% non-revenue water rate is not a drought-era anomaly but a chronic condition. What the current drought exposes is the gap between the system's designed capacity and its actual delivery performance. When reservoir levels drop below thresholds that trigger rationing, the margin for error in a leak-heavy distribution network narrows quickly. Households that already experience intermittent service under normal conditions face complete shutoffs for 48-hour windows.
The 48-hour rotating shutoff is an emergency demand-management tool, not a long-term solution. It reduces draw on the Carraízo reservoir by alternately cutting supply to half the served population, buying time for reservoir levels to stabilize. Whether that stabilization occurs depends on rainfall in the coming weeks. Puerto Rico just experienced its driest July on record, and drought Monitor data shows conditions are widespread rather than localized.
For affected residents, the practical consequences are immediate and severe. A 48-hour loss of running water affects sanitation, food preparation, medical care for home-bound patients, and basic household function. The rotating structure means that even when one group's supply is restored, the other goes dry, creating perpetual uncertainty about when water will be available.
The price-control order from DACO signals that authorities anticipate secondary market pressures, bottled water shortages and potential gouging, as residents seek alternatives during shutoff periods. Whether the controls are sufficient depends on supply chain depth for alternative water sources and the scale of enforcement capacity at the consumer-protection level.
Looking at what this means for governance and infrastructure policy, the Carraízo crisis is likely to intensify scrutiny of PRASA's non-revenue water problem. A utility losing 65% of its output to leakage cannot be made resilient through rationing alone. The structural fix, pipe replacement and network modernization, requires capital investment and execution timelines measured in years, not drought cycles. In the interim, Puerto Rico's water security hinges on weather patterns cooperating with a distribution system that wastes more than it delivers.
