was, after all, putting my health and my digestive tract at risk here, but it was all for a good cause – wasn’t it
The river runs through farmland infested with rats as they scavenge spilt grain. The females may carry the Leptospirosis virus (Weil’s Disease) carried in their urine, which in turn can enter river water and prove fatal if contracted by humans through ingestion.
To add further cause for concern, there was a sewage outfall just half a mile upstream, and industrial estates dumping who knows what into the waterway beyond that.
I closed my eyes and shakily squeezed the bottle. Liquid poured from the spout and into my mouth. I took a sip, then a gulp. The water tasted good. It was crystal-clear, without any hint of an odour or of noticeable bad tastes.
I swallowed, it was done now – I’d have to wait a while and monitor myself to see if I was going to be in need of medical assistance.
I had put my health on the line to test the latest in portable water filtration systems in the Water To Go bottle...

The Function
The maker claims that this filtration system differs from anything else on the market. The filtration takes place as you drink.
Using materials apparently developed at the request of NASA, the filters contain a “charged layer membrane” containing nano alumina and carbon, which emits a positive charge when wet and attracts and holds negatively charged impurities.
The filter is said to remove 99.9% of all contaminants from water, including seriously nasty viruses and bacteria. Unfortunately, the only thing it won’t filter is sea water.
Each screw-in filter is good for around 200 litres of use and can be easily changed. Unless you keep track of the amount of water that has passed through the filter, how do you know if it needs to be replaced? The maker says: “The filter continues to do its job for much longer than 200 litres; we use activated carbon to improve taste and smell, so, as an indication, if the water tastes less good, it’s time for a filter change.”

In Use
The Water To Go bottle could hardly be easier to use; it’s a tough, flexible plastic canteen with a screw-on top, fitted with a flip-shut nozzle and a screw-in filter. All you need to do is fill it with untreated water, open the nozzle, give it a squeeze and it filters as you drink.
It takes quite a determined squeeze and suck to get a full mouthful, because the water has to pass through the filter system, but a small valve in the lid allows air in to equalise the pressure, making things a little easier.
The tests went well, by the way, and I can’t tell you how happy I am to report that there were no signs of ill-effects from drinking the filtered dirty river water. Phew!

Conclusion
I can think of a lot of applications for this product for travelling divers, but there is one huge overriding factor that will always now see the Water To Go bottle in my dive or travel bag.
Every time I fill it from a suspect water source, river or muddy puddle, it means one fewer plastic water-bottle discarded into our oceans or ending up in a landfill site, killing our aquatic inhabitants or leaching poisons into the Earth.
Yes, I’m a conservationist. I’m a diver, after all, and I love our underwater world. I’ve seen rafts of plastic bottles being washed out to sea in Far Eastern countries, and the never-ending plume of thick black smoke billowing from Rubbish Island in the Maldives, and I’m sick of it.
So in my own little way I’m making an effort to reduce plastic pollution by investing in this filtered-water bottle. It makes economic sense too, saving enough money on bottled water purchases to pay for itself in a reasonable time.
If enough people follow my example, those millions of empty plastic water-bottles dumped into the sea around the world each day may eventually become a distant memory. From a conservationist’s point of view, this product has my full attention, and it works very well.
