Can You Drink the Tap Water in San Juan?

San Juan's tap water is supplied by the Puerto Rico Aqueduct and Sewer Authority (PRASA) and is regulated under the US Safe Drinking Water Act, enforced by the US Environmental Protection Agency (EPA). Puerto Rico is a US territory and its drinking water standards are identical to those applied across the mainland United States. The water is sourced primarily from surface reservoirs including the Carraizo and La Plata reservoirs, treated at modern facilities, and distributed throughout the San Juan metropolitan area. The water is safe to drink directly from the tap.

San Juan's tourist districts — Old San Juan (Viejo San Juan), Condado, Isla Verde, and Miramar — are served by the same municipal supply and tap water in hotels, restaurants, and residences throughout these areas is safe. Old San Juan's historic infrastructure is well-maintained by PRASA standards. Condado and Isla Verde, which host the majority of San Juan's hotel strip and beach resorts, have modern plumbing throughout their hospitality sector. Visitors can drink tap water with confidence across all of San Juan's tourist areas.

The significant caveat for San Juan is hurricane vulnerability. Hurricane Maria in September 2017 caused catastrophic damage to Puerto Rico's water infrastructure, leaving large parts of the island without safe water for extended periods. PRASA has invested significantly in infrastructure resilience since 2017, but Puerto Rico remains in the Atlantic hurricane belt and severe storms can disrupt water safety. During or immediately after a major storm event, follow local advisories and use bottled water until the all-clear is given.

San Juan is a vibrant destination combining Spanish colonial architecture in Old San Juan, excellent beaches at Condado and Isla Verde, and a thriving food and cocktail scene. The city's cuisine — including mofongo, fresh seafood, and some of the Caribbean's best rum — is a major draw. Restaurants and bars throughout San Juan use the same safe municipal tap water, and ice is safe throughout the city's hospitality venues.

For day trips from San Juan to El Yunque National Forest, Culebra, or Vieques, tap water remains safe throughout Puerto Rico's urban and suburban areas. In El Yunque and more remote areas, stick to treated tap water or bottled water rather than consuming untreated natural water sources. US brands and Puerto Rican bottled water are available throughout the island at prices similar to the mainland.
