Dear B-A,
I have recently come across LifeStraw http://www.vestergaard-frandsen.com/lifestraw
, a small (22cm x 3.5cm), lightweight (approx 30g) tube, with a
mouth-piece at one end. It will filter out a minimum of 99.9% of
bacteria, viruses and protozoans. With a LifeStraw, you can safely
drink water from sources which you would normally hesitate to wash in.
A personal LifeStraw will purify up to 1000 litres of water ( or to
put it into context, the equivalent to one pallet of bottled water).
There is also a "family" LifeStraw, which has a grater flow rate and
is capable of purifying up to 18,00 litres of water, which would be
useful for use in semi-permanent camps.. While our town water supplies
are, usually, drinkable, having to cart your own water everywhere can
be a bit of a pain. Being able to safely drink water from just about
any creek, dam or water-hole, does have its advantages, especially if
you are stuck out in the bush somewhere. A useful thing to add to your
emergency kit. Unfortunately I don't think it will make bore water any
more palatable.
I bought a couple from the local agent http://www.lifestraw.com.au/default.asp
, cost $20.95 + p&p. I am going to Sabah next month and will try
mine out in a variety of waters. It will be interesting to see what
the Kinabatangan water tastes like.
Profits from sales of LifeStraw are used to subsidise the distribution
of LifeStraw to individuals and communities in the third world. A nice
idea, buy one and reduce your own water supply costs when birding and
help save the lives of others.
I have no affiliation commercial or otherwise with LifeStraw, apart
from being a customer who thinks it is a brilliant concept.
Cheers,
Carl Clifford
