What are the sources of drinking water supply during trekking ?

During the trek, access of drinking water is an essential consideration, and there are several sources of drinking water available along the trail. However, you must ensure that you treat the water properly to avoid any health issues like waterborne diseases.

1. Teahouses and Lodges

• Teahouses and lodges are the primary sources of drinking water during the trek. They are found at regular intervals along the trekking route,

These establishments typically provide:

• • Bottled Water: Most teahouses sell bottled water or mineral water, which is convenient but more expensive (especially as you go higher in altitude). Prices can increase dramatically at higher elevations.
  • Filtered or Boiled Water: Many teahouses provide filtered or boiled water for trekkers. The water is either treated in the lodge’s filtration system or boiled to kill any harmful microorganisms. Some places may charge a small fee for the water, but it’s generally safer than untreated sources.

2. Natural Springs and Rivers

• Along the trekking route, there are natural springs and rivers at various altitudes. While the water from these sources may appear clean, it is important to treat it before drinking, as it could be contaminated with harmful bacteria, viruses, or parasites.
  • Rivers: Freshwater streams and rivers are common along the trek, but water from these sources is not safe to drink untreated. You must purify it before drinking to avoid stomach issues.

3. Water Purification Tablets or Filters

• Given that natural water sources may not be safe to drink directly, it is highly recommended that you bring water purification tablets, a water filter, or a UV purifier to treat any water you collect from rivers or streams. Common options include:
  • Water Purification Tablets: Simple, portable, and effective in killing most harmful bacteria and viruses. Brands like Micropur or Aquamira are commonly used by trekkers.
  • Portable Water Filters: Devices like Sawyer Squeeze, LifeStraw, or Katadyn are popular and effective for filtering out harmful microorganisms from untreated water sources.
  • UV Purifiers: Steripen is a popular UV purification device that uses ultraviolet light to kill bacteria, viruses, and protozoa.

4. Bottled Water

• Bottled water is available at teahouses, especially in lower-altitude areas.  However, as you climb higher, bottled water becomes more expensive and less readily available, bottled water is hard to find and can be prohibitively costly.

5. Boiling Water (Preferred Option)

• Boiling water is one of the safest methods to ensure drinking water is free from harmful pathogens. Many teahouses provide boiled water, which is the safest option available. The water is boiled at high altitudes to ensure it is free from bacteria and viruses.
  • Some teahouses may provide this service for a fee. At higher altitudes, boiled water is often the best option, as it is generally considered safe for drinking.
