Living in an ecologically sustainable way in Hawaii for three months really changed us for the better. We think twice about everything we do now, from turning off the water while we lather up in the shower, to choosing what to buy carefully to reduce packaging and waste.
On our way to Asia, we were very concerned about the fact that you can’t drink the water. We were looking at being relegated to buying large quantities of water in 500ml-1litre plastic bottles. And all in a place where “recycling” is truly a foreign word.
I cringed at the thought of throwing away plastic bottle after plastic bottle, not to mention the money we would spend for this privilege; the privilege of having clean water.
But we managed to find a viable alternative to this wastage: a way to sterilize water on the go, and all in a small compact solution that easily fit into our bags; SteriPEN was our saviour.
SteriPEN uses ultraviolet light to eliminate all the bad stuff that makes water harmful; from bacteria to viruses. The only pre-requisite is that the water be clear to begin with – no muddy creek water allowed. So whatever came out of the taps where we were traveling was more than sufficient.
Initially we were a little apprehensive about using a tiny little light to sterilize water that had the very real potential to make us incredibly ill (even fatally so), and then to have the guts (literally and figuratively!) to drink said water. But we’re still here to tell the story, so all I can say is…it worked!
Although we had to pay about $100 for the SteriPEN, we never had to purchase water in countries where that’s conventionally the only option, and of course saved (and continue to save) the consumption of hundreds of plastic bottles.
It takes a little extra planning and effort to sterilize a few litres of water (at a whopping 90 seconds a pop) each morning and evening, and then to carry around our ultralight reusable water bottles all the time, but what a savings it has brought both our pockets and the environment.
Let’s do some math:
- We were on the road through Asia for about 45 days.
- At approximately two litres of water consumed each per day, we consumed 180 litres of water.
- Most bottled water came in 500-750ml quantities, which meant the equivalent of 270-360 bottles of water was consumed.
- The cost of a bottle of water averaged out to be a little less than 50 cents. Which meant that we saved about $150 (300 bottles times 50 cents) in buying water.
- The SteriPEN more than paid for itself during our Asian trip. And now we have it for all future travels through countries where the water isn’t safe to drink. It’s all gravy (or rather, water) from here on.
And yes – we did falter here and there. Some days we didn’t have enough water with us, or forgot to bring it along. During our entire trip, we had to buy a few bottles: 11 to be exact. Which is still better than 360 if you ask me.
We even sweetened the environmentally friendly factor by purchasing the SteriPEN Ultra model, which is USB rechargeable. No disposable batteries to worry about!
If you are planning a trip that may take you into an area where the water is not drinkable, consider the alternative to buying (and wasting) your way to hydration. I can say from experience: the little light works. Save a few bucks and a few bottles too.
2018 UPDATE: Be very careful using the SteriPEN on tap water in countries where there are heavy metals. Although the SteriPEN will take care of any ickies like bacteria and parasites, it can’t filter out particulates. After spending a year in Asia in 2017/18 drinking and sterilizing all manners of tap water, I am a bit concerned that I may have subjected myself to heavy metal poisoning – in Vietnam in particular. (This was a process that inspired a hilarious detox process in Koh Phangan).
If you want to filter and sterilize your water, consider using Grayl (which I like because you can filter/sterilize water and fill your reusable bottles for a day of sightseeing) or Life Straw (which goes everywhere with you but requires having somewhere to refill the bottle as needed…as well as always having to drink your water through a straw filter).
