Uk Flooding and Potable Water
« on: February 19, 2014, 09:14:00 AM »
Now at the outset, let me caveat by saying I take 99.99% of news media output with the dose of salt it deserves. 'Freddie Star ate my Hamster' probably remains the most relevant, well researched and accurate reportage of the last 50 years.  ;)

But I'm seeing image after image of flooded areas, towns etc in the Southern UK. Also seeing many people wandering through said flood waters with seeming impunity.  Other than the odd shot of some bottled water, there doesn't appear much if any concern of warning regards contamination in either the flood water or tap water.  Yet bitter experience of flooding up here - Moray - in previous years had such issues as a priority.

I know two Police Officers who ended up being forced to retire with very poor health after exposure ( in the line of duty ) to flood water.  Friends who have covered overseas flood disasters etc tend to place secure potable water production as a high priority - to the extent of taking personal gear in addition to official supplies.

A quick review of the Government website seems to play down most issues with helpful advice such as ' if your tap water tastes a bit funny call the water company its their responsibility'  ' and boil it for now'. So chemical contamination seems zero concern.

I have three different filter units - PreMac. Surviva Pure Canteen and a Lifesaver Unit  and a couple of Millbank Bags. Ok, so I teach Bushcraft and work outdoors, but  am I just the saddest paranoid in the village or something? You can give it to me straight  ;)

Interested to hear from anyone down there and those with hands on experience as to what I've missed  and given the Forum Section Title, interested what people use/ recommend for treating water.

The Lifesaver bottle is probably one of the best things to have considering how incredibly effective it is.

A former colleague of mine was working in local flooding a few years back and acquired some virus or other (he was wading up to his waste in flood water, which at the time I thought was a bit silly considering the sewers would have been flooded as well). He lost his voice for about 2 months and it's still reoccurring a problem for him now (weakened one half of his voice box so it can't function properly whenever he gets a bad cold).

Unless you have a proper barrier protection from flood water, I wouldn't go wading in it.

But back to your point - yes, the Lifesaver bottle is one of the best things to have http://www.lifesaversystems.com/
I don't know it all and when I think I do, I tend to find karma is just around the corner...

There was an item on R4 'Today' programme the other day about how people are dealing with bodily waste in the floods; not pleasant, and no advice or help from the authorities.  There has been discussion about outbreaks of diseases like typhoid and cholera (admittedly, in the sensationalist media...)

Provided water supply pressure is maintained, the positive pressure in the distribution system ought to keep contaminated water out of the system; certainly, when repair work is done and the pressure is turned off, the usual recommendation is to run the system through (I've received a card through the door on a couple of such occasions).

However, the University of Reading (my local), apparently beg to differ, and advise that tap water in flooded homes should not be drunk (without treatment).  Whether this is due to contamination within the system, or from contamination of the taps is unclear.

I have an inline filter from DrinkSafe Systems, but it does need a pre-filter for sediment (or use a flocculant).

Thanks for the responses - just to be clear, not looking to be doom n gloom etc, just struck me as odd it hadn't featured more 'publicly' - given secure potable water is top of the list in most such events.

Given the expertise on here I was keen to explore/ develop my knowledge from hands on experience from others - and not least those who are in the affected areas.

I have the advantage/ disadvantage - moveable feast - of a private well up at the cottage and sitting as the highest property around.  Though the 3/4 mile forest track is a weak point  and has been washed away a few times.  I stalk extensively around the headwaters of the River Lossie - which is a quiet trickle you can step across in places. Local clients - who have had the self same river flowing at 4 feet through their living room in Elgin find it hard to credit!

The UK company Drinksafe Systems seem like they have decent products. Water purification filter which handles down to 0.1 micron particles including protozoa, virae etc.

I bought their system which can be used in a number of different ways. 1. Connected to a camelbak, 2. Connected to the tap, 3. As a big straw. GBP 39 is reasonable compared to other systems.

Back in 2010 I spent almost a month in Pakistan assisting the relief operation following their devastating floods. The single biggest threat to life were not the rising waters, from which, tragically around 2,000 people died, it was the further 20,000 fatalities from waterborne contaminants, from bacterial and viral diseases to chemical pollutants and toxin from factories and warehouses which had been flooded.

Even though the waters were mostly not that deep and most certainly not fast flowing, we travelled everywhere locally using inflatable rigs which when alighting back at our base we rinsed our suits in running water then disinfectant.

When the flood waters in southern England and Wales rose they must have brought with them raw sewage. I don’t know the recorded incidence of disease from waterborne disease from this flooding and if, as I suspect it is low, why this is the case.

Krenaud, I, like Oakleaf, have not come across Drinksafe Systems product before, it looks good, how would you rate it marks out of 10?

Your hide-away sounds perfect Oakleaf. We too live in a cottage with a lengthy track, which being the Lake District, frequently has sections washed away, but no deer stalking as there are too many people ;)

Lyle, I cannot rate the Drinksafe system as I haven't been out for any longer trips outdoors since I bought it and anyway in winter water filters are a no-no since ice crystals may form and damage them.

The reason I chose it is that I wanted an alternative to my Katadyn Vario which also can handle virae. Here in Sweden filtering out bacteria and protozoa is usually enough, but it's nice with extra safety.

Bottles with built in filters are good, but then each person in the party must have their own so that's why I liked the Drinksafe. It can be used either in-line with the camelbak or as a gravity fed system to fill bottles or even connected to a tap. (Note: When using with a tap, you must put the tap on drip)

My water treatment methods have evolved over the years.
I start with a pre-filter for particulates (1.0 micron absolute), followed by a Sawyer Mini Filter (0.1 micron absolute), and then either Aquamria drops or SteriPEN Purifier for virus treatment.

In the winter, I tend to go with the pre filter, followed by SteriPEN as I don't have to worry about the unit freezing and being ruined like I do the Sawyer filter.

Review I just did on the new SteriPEN Ultra:

Food ( or rather drink?  ;) - for thought - many thanks AoP.

Plus 'repurposed' is going to be my word of the week!  Its interesting to get varying perspectives - thank you everyone taking time to read/ post etc.

I think that the answer is that the diseases have to be present in the environment anyway. Hence areas such as in Pakistan, where some of these diseases are endemic, suffer when floods occur and that this is not the case on the Somerset flood plains where these diseases are rarely, if ever, present.

Interesting perspective Callum. I'm not well enough up on biology to comment for certain.  However, same applies up here - yet that policeman was critically 'injured' but some bug carried in the water.

But unless there is a conspiracy/ cover-up of epic proportions ( and as an ex 'civil servant' and seeing the effort that goes into just getting a new stapler organised, I really dont go for conspiracy theories!  :) )  then the proof is in the pudding - not seen any reports of any major illness amongst the flooded areas.  Which would tend to support Callum's note.
