Why Your Students Can (And Should) Drink Stream Water While Trekking
What is bottled water?
Bottled water is tap water from municipal water supply sources which goes through additional filtering. What you’re paying for isn’t purity; you pay extra for packaging and clever marketing.
Bottled water isn’t better
- Bottled water is treated tap water, stored in plastic for months. Studies have shown that many bottled brands contain microplastics or chemical residues.
- Bottled water is continually exposed to heat during transportation from the plains, and even on the shelf in stores. This can cause bottles to leach harmful chemicals into the water over time.
- Carrying crates of bottled water up a mountain is unnecessary. It adds to the load (porters and mules) and leaves mountains of waste behind.
- Did you know that plastic bottles take a minimum of 500 years to decompose? We think we’ve done our bit by discarding bottles in a dustbin, but they typically end up in landfills.
For perspective, during the period January 2024 to December 2025, the Indiahikes team collected a whopping 6605 kilos of waste from the mountains.
How we ensure safe drinking water on InSOUL treks
We follow strict protocols to ensure that water is managed safely and responsibly on our treks.
Drinking water comes from two main sources on a Himalayan trek: campsites and streams along the trail.
At campsites, it is standard practice to fetch water from a higher point, away from where people are. Water is either boiled or purified before being used in the kitchen or for drinking.
While on the trail, children can safely refill water from flowing streams. The water from flowing streams is clear and fresh. The trick is to prevent disturbing the stream flow while filling up water bottles.
For added precaution, consider carrying small filtration devices that you can pop into your bottle of water.
Trek organisations everywhere rely on natural streams for water, unless the terrain is dry; then we carry water from the last available source.
