Puerto Rico’s Water Crisis Isn’t a Drought Problem. It’s a Decades-Old Infrastructure Crisis

SAN JUAN, P.R. — For more than two months now, tens of thousands of Puerto Rican residents across the capital of San Juan and its surrounding municipalities have gone without reliable running water — hauling five-gallon jugs up apartment stairwells in summer heat, paying $70 to $100 a day to secure water from public cisterns, and watching elderly and disabled neighbors end up hospitalized.

The immediate trigger was a burst pipe, but the underlying cause is decades old.

What Happened

The crisis began in mid-June, when Puerto Rico’s Aqueduct and Sewer Authority (PRASA, known locally as AAA) detected a rupture in the 72-inch Superaqueduct pipeline in Bayamón, one of the island’s most important water distribution arteries, with breaks at three separate points. While repair crews worked to stabilize the line — reinforcing it overnight with concrete and chemical accelerants — two additional outages emerged elsewhere in the system, compounding a crisis that ultimately affected more than 100,000 people across San Juan, Bayamón, Guaynabo, Caguas, Juncos, and Loíza.

Governor Jenniffer González Colón activated the National Guard in June, deploying tanker trucks to circulate through affected communities, and PRASA has coordinated with the Departments of Housing and Family, the Tourism Company, and municipal governments to distribute drinking water directly to residents.

Some communities in San Juan’s eastern corridor had already been enduring nearly a year of intermittent service before the Superaqueduct rupture, following the August 2025 failure of two pumps at the Finca Rosso I station — meaning for a meaningful share of affected residents, this crisis didn’t begin in June, but have been enduring the crisis for much longer.

The Real Number: 59%

The single most important statistic in understanding Puerto Rico’s water crisis has nothing to do with rainfall. Approximately 59% of all treated water on the island is lost before it ever reaches a resident — leaked through aging pipes, stolen via inaccurate meters and unauthorized hookups, or simply swallowed by crumbling infrastructure.

More than half of Puerto Rico’s drinking water supply has been lost this way over the past two decades. As one local politician put it, that’s the equivalent of a business losing half its inventory every year and treating it as normal operating conditions rather than a crisis.

PRASA serves roughly 3.2 million residents through a network of reservoirs, rivers, treatment plants, pipelines, and aquifers — much of it, according to engineer Carl Soderberg’s reporting in El Nuevo Día, dating back to the 1940s and 1950s and already well past its useful operational life.

The utility’s structural weaknesses compound the aging infrastructure problem: PRASA doesn’t control the electrical grid its pumping and treatment systems depend on, and it holds jurisdiction over only 8 of the island’s 36 reservoirs. Two of its key reservoirs, Dos Bocas and Guayabal, have lost 70% and 50% of their storage capacity respectively due to accumulated sediment that was never dredged.

A Drought Is Making It Worse, But Didn't Cause It

Compounding the infrastructure failure is a genuine climate factor: an intense El Niño pattern has helped push 2026 toward becoming the warmest year on record, and advancing saltwater intrusion has led Puerto Rico’s Department of Natural and Environmental Resources to formally declare the island's Southern Aquifer in critical condition.

Authorities have warned that conservation measures may be necessary if drought conditions persist through the coming months. But as El Nuevo Día’s editorial board argued this week, treating the crisis as primarily a rainfall problem is, in their words, an insult to Puerto Ricans’ intelligence — the structural crisis predates any drought by years, and a wetter season would not fix a system losing 59% of its water before it reaches anyone’s tap.

From Voluntary Appeals to Mandatory Rationing

In the weeks since the initial Superaqueduct crisis, the drought component of Puerto Rico’s water problem has escalated sharply, and Governor González Colón’s response has moved well beyond asking residents to conserve. She has repeatedly called on Puerto Ricans to cut back on non-essential water use — specifically citing car washing, hosing down driveways and sidewalks, watering plants, and filling pools — telling residents directly:

“We have to be very careful with water use... this thing of hosing down driveways, hosing down sidewalks, watering plants, washing cars, filling plastic pools — we have to be very careful.”

That appeal has since hardened into policy. González Colón signed two executive orders declaring a formal state of emergency over water use, citing severe drought conditions affecting roughly 25% of the island and moderate drought across another 36%, and activating the National Guard specifically to assist with water hauling, distribution, and purification.

Days later, her government went further, implementing actual mandatory rationing: 48-hour scheduled service interruptions beginning this past Friday for the roughly 180,000 customers served exclusively by the Carraízo reservoir, spanning San Juan, Carolina, Trujillo Alto, Gurabo, Loíza, Canóvanas, and Juncos.

The reservoir’s condition explains the urgency. Carraízo currently sits at 37 meters; once its level drops to 30 meters, water can no longer physically reach the system’s intake structures. Puerto Rico’s National Weather Service has forecast no significant rainfall over the following two weeks, and AAA’s executive director, Luis González Delgado, described 2026 as an unusually challenging year given the effects of an intensifying El Niño pattern, compounded by Saharan dust that has been suppressing rain formation over the island.

In a moment that drew notable attention, González Delgado and the governor both publicly invoked prayer as part of the response, with González Colón telling reporters: “I hope we all ask God for rain.”

The governor has so far declined to impose fines for excessive water use, saying AAA personnel need to stay focused on maintaining service and repairing leaks rather than enforcing penalties, and that she trusts residents to act responsibly.

González Colón has requested authorization from Puerto Rico’s Fiscal Oversight Board to access the island’s Emergency Reserve Fund to help finance the response, and her government has assigned dedicated agency liaisons to each affected municipality to coordinate resources directly.

A Pattern, Not a One-Time Event

This is not Puerto Rico’s first water emergency, and officials involved in the current response have acknowledged as much. A nearly identical crisis occurred in July of last year, when the rupture of a 54-inch water main left close to 200,000 people without water, drawing headlines specifically because of its impact on tourism and planned concerts.

The response then mirrored the response now almost exactly: National Guard mobilization, emergency water distribution, and public acknowledgment that deferred maintenance was the root cause. PRASA’s leadership has said the utility will launch an “aggressive agenda” of inspections and long-overdue maintenance work — language nearly identical to commitments made after prior crises.

Political & Legal Fallout

The San Juan mayor’s office has sued the island’s water authority over the crisis, and Puerto Rico’s Independence Party (PIP) has pushed the island’s government to adopt a comprehensive plan covering the entire water supply system rather than responding to individual pipe failures as they occur.

PIP representatives have specifically called for depoliticizing PRASA’s management and building accountability structures that hold the agency responsible for the kind of losses that would bankrupt a private business operating the same way.

Why This Keeps Happening

Puerto Rico’s water crisis sits alongside its long-running electrical grid failures as one of the clearest markers of the island’s compounding infrastructure debt — a burden shaped by decades of underinvestment, a 2014 government debt crisis that triggered federal oversight through the PROMESA board, and budget constraints that have repeatedly delayed the capital investment PRASA’s own engineers say is necessary.

Whether the current government’s promised inspection and maintenance push produces a lasting fix, or simply defers the next rupture to next summer, will likely depend on whether the capital investment PRASA has needed for decades actually materializes this time — something residents living through their second major water crisis in as many years have real reason to be skeptical of.
