How Does Water Safety Work in Nepal?
Last verified: 2025-06 · Asia
1The Quick Answer
Never drink tap water in Nepal — use bottled, filtered, or purified water at all times including on trekking routes.
2What You Need to Know
Tap water throughout Nepal is not safe to drink and can cause serious gastrointestinal illness. In Kathmandu and Pokhara, refill stations selling filtered water are widely available and far cheaper and more eco-friendly than single-use plastic bottles. On treks, boil water from streams or use purification tablets and a filter; most teahouses charge a small fee for boiled water. Altitude dramatically increases dehydration risk — drink 3–4 litres per day while trekking. Avoid ice in non-tourist restaurants as it may be made from tap water.
3Practical Tips
Practical Tips
- 1Carry a quality water filter bottle (like LifeStraw or Sawyer Squeeze) on any trek to purify stream water for free rather than paying teahouse prices all the way up.
- 2Use refill stations in Kathmandu (around 5–10 NPR per litre) rather than buying plastic bottles — it saves money and reduces plastic waste.
- 3Brush your teeth with bottled or filtered water, not tap water, even in Kathmandu's better hotels.
Important Warning
Giardia and other waterborne parasites are common; a single lapse in water vigilance on a trek can ruin your entire trip with days of illness far from medical help.
