Water, water, everywhere?
kit, reviews No Comments »After a couple of days feeling sorry for myself with a heavy cold, I decided to get out from under the bedcovers and head for the woods. With a certain amount of coughing and spluttering, I climbed into the van and made it to Broaks Wood. I took the minimal amount of kit, just a sit mat, water, and sandwiches. The weather was still an incredibly mild 17 degrees C and the sun was shining like a spring day. Just what the doctor ordered for lifting the spirits and sweating out a cold.
An ulterior motive for going out today was to test out my new pre-mac pocket water purifier. I had often thought about water purification and how I was going to address it. Being one of the key survival items, I’m surprised at myself for leaving it so long before I did.
Where I live in East Anglia UK, there is very little flowing water. We have very few flowing rivers and streams quickly dry out especially in summer. We have the lowest rainfall in the UK, so if you don’t take water with you on an excursion, it will be hard to come by. But what if you do run out? On hiking or camping trips in other parts of the country with access to running rivers, you could probably get away with collecting water a merely boiling it.
In this part of the country, it’s another matter. Looking through the web forums, I decided to buy a Premac water filter. There are several types of pre-mac, the pocket being the smallest and cheapest, but it is a throwaway version lasting about 60 litres. I have heard that if you look after them and use a secondary filter (like a pair of tights or stockings) they can last longer. Mrs Pablo might get a shock when she finds the toes of her tights cut out. Wasn’t me. The quality of the water source is obviously another factor which will increase filter longevity.
The pre-mac couldn’t be easier to use. Put the filter in the water source, and after priming, pump away until the water comes out of the outlet. I was quite surprised how quickly you could pump a litre of water. I used a baco foil tin to collect the water and you could easily use a second tin to collect the water from the source to make things easier. On the instruction label it said that the water should be left standing for 2 minutes to allow the chemicals to work. After that, you’re all set. It’s recommended that the water source is flowing and preferably over a gravel bed which really goes without saying.

I was a little dubious about drinking the water straight, and decided that in an emergency situation it could be done although boiling first would be preferable. I was a little more assured as I read on the pre-mac label that the unit had been tested and approved by the London School of Hygiene and Tropical medicine. That’s good enough for me. This little bit of kit will certainly be a permanent feature in my small utility bag.
Well, that was all I could manage this weekend. A couple of short outings but I certainly feel a lot better. The picture was taken with my phone, hence the lower quality image.
