PRASA’s 48-hour rotation affects 180,000+ customers as drought and leaky pipes cripple the grid. Here is how to cope.
Puerto Rico water rationing is now a daily reality for more than 180,000 customers across San Juan and six neighbouring municipalities. The water utility PRASA flipped the switch on August 7 and 8, 2026, imposing a strict 48-hours-on, 48-hours-off rotation that officials say will last at least through the end of the month. If you live in or visit the capital area, your taps will run dry for two full days at a stretch. Plan around the schedule, stock up wisely, and know that this could stretch further. Roughly half a million people are caught in the rotation, and the underlying causes — a brutal drought and a crumbling pipe network — show no signs of easing.
Key Facts
- Affected area — San Juan plus six municipalities: Carolina, Juncos, Gurabo, Trujillo Alto, Canóvanas, and Loíza.
- Scope of impact — More than 180,000 customer accounts, roughly half a million people, per Reuters and NPR.
- Rationing schedule — 48 hours on, 48 hours off, expected to run through at least the end of August 2026.
- Drought severity — Nearly 68% of the island is in drought; over half in moderate to extreme conditions, per Reuters.
- System losses — Around 60% to 65% of water vanishes through leaks and unbilled losses, per government and expert estimates.
- Trigger event — A June pipeline rupture plus months of below-average rain pushed the Carraízo reservoir to critical lows.
Which Areas Are Cut and When: Puerto Rico water
The rationing covers the Carraízo reservoir service zone. That takes in San Juan, Carolina, Juncos, Gurabo, Trujillo Alto, Canóvanas, and Loíza.
Reuters confirmed the seven municipalities on August 6, 2026. The cycle is a straight 48-on, 48-off, so your neighbourhood either has water today or it does not.
The pattern flips every two days. PRASA has not published a firm end date, and the New York Times reports officials are watching reservoir levels before committing to anything further.
Residents in Loíza, a coastal town, face extra saltwater intrusion worries as groundwater reserves run low. That adds to the burden for families who rely on wells for backup supply.
Why the Reservoir Ran So Low
Rain has been scarce for months. Reuters put nearly 68% of Puerto Rico in drought conditions, with more than half the island in moderate to extreme drought by early August.
The Carraízo reservoir, a primary source for the capital, dropped to critically low levels. But drought is only half the story, as the pipe network is decrepit.
Government reporting cited by NPR says more than half the water supply is lost to leaks underground. Experts told the New York Times that up to 60% vanishes before it reaches a tap.
A major pipeline rupture in June made things measurably worse. It left tens of thousands without water for weeks before this rationing began.
The utility has struggled for years with aging infrastructure and underinvestment. This crisis is not sudden but the result of long-ignored repairs and climate pressures.
What the 48-Hour Cycle Means for You
When water is on, you get roughly two days of normal pressure. When it is off, expect nothing from the taps for 48 hours.
There is the possibility of extension to 72-hour cuts, according to CBS News. So do not treat the current schedule as fixed.
Fill bathtubs, large pots, and clean containers during the ’on’ window. Boil anything you plan to drink if you are unsure of storage hygiene.
For expats and nomads, this is the moment to check whether your apartment building has a cistern or roof tank. Buildings with storage often ride out the off-cycle without noticeable interruption.
Keep wet wipes and hand sanitizer handy for basic hygiene when water is off. Simple preparations reduce panic during the dry days.
The Numbers Vary: People, Accounts, and Households
You will see conflicting totals in the news, and that is because sources count differently. Reuters reports more than 180,000 customers.
CBS News says over 180,000 customer accounts. NPR estimates roughly half a million people affected.
Do not add these figures together, for they measure different units — accounts versus individuals versus households. The practical takeaway is the same: hundreds of thousands of people in the capital region are living on a two-day cycle.
What Comes Next and How to Prepare
Forecasters do not expect significant rainfall in the weeks ahead, NPR reported. PRASA has not said when rationing will end.
The practical assumption for residents and visitors is that August will be dry. There is a real chance the rotation continues into September.
If you are planning a trip to San Juan or the eastern municipalities, call your hotel or rental host directly. Ask whether the property has backup water storage.
For those living here, consider investing in a small 50- to 100-litre tank and a basic filter. A little preparation turns a two-day dry spell into an inconvenience rather than a crisis.
Municipalities are opening community filling stations at public plazas and schools. Check local announcements for the nearest spot during the off-cycle.

Frequently Asked Questions
Which areas of Puerto Rico are affected by the water rationing?
PRASA is rotating water across San Juan, Carolina, Juncos, Gurabo, Trujillo Alto, Canóvanas, and Loíza. All of these sit in the Carraízo reservoir service zone.
How long will the water rationing last in Puerto Rico?
Officials say the 48-hour on, 48-hour off schedule will last at least through the end of August 2026. No firm end date has been announced, and forecasters predict little rain in the coming weeks.
Why is Puerto Rico experiencing this water crisis?
A severe drought left nearly 68% of the island dry. Ageing infrastructure makes it worse: experts estimate 60% to 65% of water is lost to leaks and unbilled usage before reaching customers.
What should I do to prepare for the water cuts?
Store water in clean containers during the 48-hour ’on’ window. Fill bathtubs for flushing. If you are a visitor, confirm your hotel has a backup cistern or storage tank before you book.
