Puerto Rico's Water Rationing Crisis: Drought Meets Aging Infrastructure
More than 500,000 people in Puerto Rico are living under government-imposed water rationing after the island recorded its driest July on record, leaving the Carraízo reservoir critically depleted. BBC
The rationing scheme is run by Puerto Rico's water utility, Autoridad de Acueductos y Alcantarillados (PRASA). It works by splitting affected households into two groups: each group has its water supply shut off for 48 hours on a rotating basis, meaning hundreds of thousands of residents go without running water for two days at a time. Seven regions served by the Carraízo reservoir are affected, covering 180,000 properties.
Governor Jenniffer González said the rationing was put in place due to weather conditions that left the reservoir depleted, and that the decision followed a careful evaluation of the reservoir's condition alongside weather forecasts. The US Drought Monitor confirms that most of Puerto Rico is facing moderate to severe drought, with 68% of the island under drought conditions.
The immediate trigger is a lack of rain. But the conditions making this crisis worse are man-made. PRASA loses roughly 65% of the water it produces as "lost or unbilled" — meaning water that never reaches paying customers, largely because of leaks in aging pipes. That figure means the utility delivers barely a third of its output to customers before rationing even enters the picture. In a system already losing more than half its supply, a drought of this severity worsens an existing infrastructure problem rather than creating a new one.
Puerto Rico's Department of Consumer Affairs (DACO) has responded 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 like these typically aim to prevent price-gouging during emergencies — when sellers might artificially inflate prices because demand spikes — though their effectiveness depends on enforcement details that have yet 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% loss rate is not a drought-era anomaly but a chronic condition. What the current drought exposes is the gap between what the system was designed to deliver and what it actually delivers. When reservoir levels drop below the 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 now face complete shutoffs for 48-hour windows.
The 48-hour rotating shutoff is an emergency demand-management tool, not a long-term solution. Think of it as a tourniquet: it slows the bleeding but doesn't heal the wound. It reduces the draw on the Carraízo reservoir by alternately cutting supply to half the served population, buying time for reservoir levels to stabilize. Whether that stabilization happens 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 constant 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.
In terms of 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 depends on weather patterns cooperating with a distribution system that wastes more water than it delivers.
