5 tips for drinking water in Nepal whilst trekking
TIP 1 – HELP THE ENVIRONMENT: Many trekkers purchase their water in plastic water bottles from shops during a trek. Although this provides profit to villagers, it also causes pollution. When you discard the empty plastic bottle in a garbage bin, it usually is not taken to a refuse site... it will either be burned or left in a rubbish pile...both are not the best way to help keep the Himalayas clean. Help the environment by taking your own REUSABLE water bottle.
TIP 2 - FREE DRINKING WATER: If you collect your water from taps and hose pipes situated along the trekking routes, you will not have to pay. The water runs directly down the hills and therefore is easy to obtain. This water will need to be boiled or purified
TIP 3 - HAVE 2 WATER BOTTLES: The best tip here is to have 2 reusable water bottles... so that you always have one bottle to drink from, whilst the water in your other bottle is being purified.
TIP 4 -IMPROVE THE TASTE: Your water, once purified, will taste like chemicals. Although safe to drink, it may not taste pleasant for you. The tip here is to pour oral rehydration salts into the water which will improve the flavour and keep you healthy. The Rehydration salts are sold in packets that contain powder and are small and light to carry. Orange flavour is usually considered the best flavour and available from most chemists in Kathmandu.
When trekking it is extremely important to stay hydrated and you will be thirsty. Hydration salts will contribute to the quality of your trek by keeping you healthy and improving the taste of the water.
TIP 5 - CARRY PURIFICATION TABLETS: Having purification tablets/iodine is best because you will not have the time to boil your water. They are small, cheap and light to carry. Even if you intend on buying bottled water or boiling your water you may still need purification tablets in the event of an emergency. Follow the instructions carefully to avoid any possible infections from Giardia etc
