Can You Drink Tap Water in Peru?

Tap water in Peru is unsafe for drinking and should be completely avoided by tourists throughout the country including Lima, Cusco, Arequipa, and all other destinations. Water treatment infrastructure is inadequate and distribution systems are heavily compromised by contamination, aging pipes, and inadequate maintenance. Most Peruvians do not drink tap water and rely exclusively on bottled water or boiled water. In Lima, the capital, tap water is treated but frequently contaminated during distribution through corroded pipes and illegal connections.

Water service is intermittent in many neighborhoods with residents receiving water only certain hours or days. When pipes are empty, contamination enters the system. Hotels in Miraflores, Barranco, and tourist areas provide bottled or filtered water but bathroom tap water remains unsafe. In Cusco and the Sacred Valley, major tourist destinations for Machu Picchu, tap water is completely unsafe.

The high altitude and limited infrastructure mean water treatment is minimal. All hotels and restaurants serving tourists provide bottled water. Never drink tap water in Cusco under any circumstances. In Arequipa, Puno, Lake Titicaca area, and southern Peru, water infrastructure is very poor and tap water is consistently unsafe.

In the Amazon region including Iquitos and Puerto Maldonado, water treatment is virtually nonexistent and tap water should be completely avoided. Jungle lodges provide bottled or heavily filtered water. Peru experiences frequent waterborne disease outbreaks including cholera, typhoid, hepatitis A and E, and severe traveler's diarrhea which affects the majority of tourists who consume contaminated water. Contamination is severe year-round. Use bottled water for all drinking, brushing teeth, washing produce, and even for rinsing your mouth after showering.

Ice should be avoided everywhere except in established tourist restaurants where you can verify purification.
