One of the best cycle touring investments we ever did was getting a Katadyn Pocket Water Microfilter.
We often ran out of water and the only thing near that looked a bit like water you wouldn’t drink as it was. We would scoop up some water with our Ortlieb “kitchen sink” and start pumping – I even managed to catch a very small fish one time.
We couldn’t just pop into a “estancia” aka farm and ask for some water, because they would often be at the end of a five or more miles long farm track. That would be 10 miles or more round trip on a very rough bit of gravel track, where we wouldn’t know if there would be water at all.
Small lakes, streams and even dirty looking puddles was our source of water. 15 minutes pumping with the Katadyn and all our water bottles were full with very nice and clean drinkable water.
If the Red Cross and the US Army, to name but a few, rely on the Katadyn – it would be good enough for us.
