Can I Drink Tap Water in Bali?

Bali's tap water contains bacteria, viruses, parasites, heavy metals, and chemicals that pose health risks, particularly for visitors. While suitable for hygiene purposes like showering and handwashing, it should never be consumed directly. The contamination levels are attributed to inadequate treatment relative to international safety standards. Water companies report approximately 30% of distributed water contains E. coli or fecal coliforms. Bottled water is widely available and recommended for all drinking and tooth brushing.

Bali's water infrastructure struggles to meet international safety standards due to outdated treatment facilities and aging distribution systems. Seven out of ten Indonesian households consume water contaminated with E. coli according to WHO data. The primary issues include bacterial contamination (causing Bali Belly, a common tourist ailment), parasitic infections, viral pathogens, and chemical contaminants. While local establishments like hotels and restaurants employ filtration systems, individual tap water sources remain unsafe. Government regulation No. 82/2001 establishes water quality standards, but enforcement and compliance remain inconsistent across the region. The water hardness is moderate, typical for tropical island regions with mixed groundwater and surface water sources.

Visitors to Bali should assume tap water is unsafe and plan accordingly. Bottled water is inexpensive and widely available throughout the island. Carry refillable water bottles and purchase bottled water from reputable vendors. Water filtration systems in restaurants are typically reliable. Be cautious with street food vendors. In hotels, tap water is generally treated but confirm with staff before consuming.
