Drinking water directly from the tap is not recommended for trekkers. Normally you can buy filtered water, mineral water, and boiled water on the trail. We request our trekkers to carry water purification tablets (if you are used to the tablets). There is a big problem of plastic bottles around the trail so it's our request that trekkers use other options. Our Guide will get fresh water from the tap if you use a purification tablet. In some places, both are not worth using in that case buying water bottles is safe.
