Puerto Rico Rations Water for 48 Hours Amid Severe Drought

Puerto Rico will implement water rationing measures in San Juan and other major cities starting Friday, August 7, affecting more than 180,000 customers who will be without water for 48 hours at a time under an alternating schedule. The move comes as the U.S. territory grapples with its most severe drought in over a century, with July 2026 recorded as the driest month for San Juan since records began in 1899, according to NBC News.

A Crisis Decades in the Making

The rationing plan affects sectors in seven municipalities served by the Carraízo reservoir: San Juan, Carolina, Juncos, Gurabo, Trujillo Alto, Canóvanas, and Loíza. The reservoir, built in 1953, is at critical levels — measuring 37.72 meters as of August 5, dangerously close to its minimum operational level of approximately 30 meters.

The water authority (AAA) needs to extract at least 80 million gallons daily from Carraízo to maintain adequate tank levels, but currently only extracts about 70 million gallons, creating a daily deficit of 10 million gallons. As Prensa Latina reported, the plan divides affected sectors into two zones with alternating 48-hour service interruptions beginning early Friday morning.

Governor Jenniffer González signed two executive orders on July 31 declaring a state of emergency for water use and activating the National Guard to assist with water distribution and purification. The emergency declaration came as the U.S. Drought Monitor reported that nearly 25% of Puerto Rico is experiencing severe drought, with another 36% under moderate drought conditions.

El Niño and the Climate Connection

The drought is being driven by a strengthening El Niño, a natural warming cycle in the Pacific Ocean that affects global weather patterns. The NOAA places a 97% probability that the current El Niño episode will persist until early spring 2027, with an 81% chance it will reach very strong intensity between October and December.

“We are seeing that El Niño continues to get stronger,” said María Novoa García, a meteorologist with the National Weather Service in San Juan, as reported by El Nuevo Día.

Ernesto Morales, coordinator meteorologist at the National Weather Service, explained that El Niño typically produces strong wind shear in the Atlantic that reduces hurricane activity but also limits rainfall from tropical waves. “El Niño is good news for Puerto Ricans because it tells us: ‘Look, there’s less cyclonic activity,’ but at the same time, if it’s a prolonged dry period, the intensity of this drought could be greater,” Morales said.

Rainfall in the next two to three weeks is expected to be at least 50% below average, and experts predict dry conditions persisting until at least September. The EFE news agency reported that the drought now affects 80% of Puerto Rico, with extreme drought conditions declared in the south-central and western strip of the island, covering 9.49% of its territory.

Chronic Infrastructure Problems Compound the Crisis

While the drought has dramatically worsened conditions, thousands of Puerto Ricans were already experiencing water shortages for up to a year before the crisis escalated. The lack of water unrelated to the drought prompted San Juan Mayor Miguel Romero to sue the island’s water and sewer authority in late May, with the governor acknowledging the agency’s infrastructure has lacked investment and maintenance for decades.

Romero has demanded clear information about the rationing plan, stating: “A measure of this magnitude requires a clear calendar, reliable information about the interruption and restoration periods, and special coordination to attend to vulnerable populations and essential facilities,” as reported by Metro Puerto Rico.

The mayor’s lawsuit, detailed by El Diario, cites recurrent service interruptions due to operational failures, lack of maintenance, and structural deficiencies. Puerto Rico Rep. Domingo J. Torres García has also threatened court action if the AAA doesn’t respond about chronic water problems, saying: “The people have the right to know what is happening, what the plans are and what concrete actions are being taken to address this crisis.”

Community Impact and Emergency Response

For many residents, the rationing announcement is merely a formal recognition of a crisis they’ve been living with for months. Sixty-one-year-old community leader Marcia Soler París said the rationing measures don’t really mean much because her neighborhood already was experiencing severe water shortages for months. “It’s chaos,” she said. “It’s truly pitiful.”

She worries most about bedridden and older people who are unable to haul heavy water buckets to their homes and apartments. Some communities in San Juan have been without water for more than 100 days, with residents in barrio Machuchal and Calle Loíza documenting outages lasting up to 118 days.

The emergency response includes large trucks distributing potable water with priority given to hospitals and residences for older people. Tania Conde Sterling, president of Puerto Rico’s Association of Health Services Administrators, called for calm, saying hospitals are prepared: “We do not improvise at hospitals. We have manuals of rules and procedures, as well as protocols for every type of scenario.”

San Juan Municipality has activated its first phase of response plan with a hotline (787-480-2025) for residents to report emergencies and request water tanker trucks.

Historical Precedent and Forward Look

Puerto Rico has faced severe droughts before, including in the early 1970s, 2015-2016 when approximately 400,000 utility customers received water only every third day, and 2020 when about 140,000 customers dependent on Carraízo were affected by rationing. The current crisis, however, is compounded by aging infrastructure and a Fiscal Oversight Board that cut $30 million from the AAA budget in early August.

As Infobae reported, two major reservoirs — Carraízo and Cidra — have had to make operational adjustments due to low water levels, while five others may need similar adjustments soon. The Cidra reservoir has already entered operational adjustment phase.

The governor has acknowledged the situation is largely out of the government’s hands, stating: “This situation is out of our hands. Nothing prevents this from worsening.” She has appealed to residents to use water prudently, declining to consider fines: “I appeal to the trust that the people will be prudent in the use of water.”

As Metro Puerto Rico reported, González has urged citizens to “prepare for the worst,” warning that if rain doesn’t fall copiously over Carraízo, scheduled interruptions could extend indefinitely.

With El Niño expected to intensify through December and the dry season approaching, Puerto Rico faces a precarious water future. The rationing plan is scheduled to continue on an alternating basis until conditions improve, but with 11 reservoirs reporting decreased water levels and an estimated 2.7 million people living in drought-affected areas, the territory’s water security challenges are far from over.

What to watch: Whether tropical waves bring meaningful rainfall in the coming weeks, how the AAA manages the rationing logistics across seven municipalities, and whether the infrastructure investment needed to prevent future crises materializes.
