Is Tap Water Safe to Drink in Papua New Guinea?

Port Moresby and a handful of provincial towns are served by utilities such as Eda Ranu and Water PNG, drawing from rivers and reservoirs, but the vast majority of Papua New Guinea's population, concentrated in rural highland and coastal villages, has no piped supply and relies on rivers, rainwater, or wells.

Urban treated water quality is inconsistent due to aging infrastructure, sediment from deforestation, and periodic supply interruptions. Rural water sources are largely untreated and carry a high risk of bacterial and parasitic contamination, particularly during PNG's wet season.

Port Moresby's central business district and international hotels typically provide filtered or bottled water for guests, since even treated municipal tap water is not considered reliably safe for visitors. Rural highlands, remote coastal villages, and outer islands carry significantly higher risk, reflecting the country's stark urban-rural divide in water infrastructure.

Variable across regions, generally moderate, though data is limited outside major towns..

Most urban residents drink boiled or bottled water rather than tap water directly, and most rural Papua New Guineans rely on untreated river, rain, or well water out of necessity.

• •Drink only bottled or filtered water in Port Moresby, even at hotels, unless it has been further treated
• •The urban-rural divide is extreme — assume any water outside a major hotel or resort is unsafe untreated
• •Carry water purification tablets or a portable filter for highland or rural travel

• •Always drink bottled, boiled, or filtered water, including in Port Moresby
• •Avoid tap water entirely in rural and highland areas, where treatment infrastructure is largely absent
