Caution:- Threat to Potable water in UK.

Water companies in the UK have been given permission to REDUCE the amount of chemicals used to purify drinking water due to distribution problems i.e. not enough HGV drivers. The Environment Agency notified firms it was permitting “a temporary reduction in the dosage used to treat both waste and drinking water”.

A spokesperson for Water UK said: “We are currently experiencing some disruption to the supply in England of ferric sulphate, a chemical used at some drinking and waste water treatment sites.

Traditional chemicals for sanitizing water include:-

  • Citric Acid Solution
  • Chlorine Dioxide
  • Sodium Hypochlorite
  • Ferric Sulphate

That’s it? Nope, not even close and there are 17 pages full of all sorts of sh’t they use when filtering, purifying, and sterilizing water. and the other 77 pages list details of pipework, linings, coatings, sealants, and repair materials. (PDF LIST)

Which makes me smile as all we have to hand is common 5% household bleach, Pool Shock, iodine, and Potassium Permanganate, Aqua tabs and Oasis Water Purification Tablets. After all variety is the spice of life isn’t it.

Would you believe I almost forgot the most common treatment?
Boiling the hell out of the water.

Inevitably there are going to a few people who run their tap and get to drink water of questionable quality and that could start little outbreaks that may include:-

Typhoid, Cholera, Giardia, Cryptosporidiosis (Crypto), roundworm, liver flukes, Weils Disease (Leptospirosis), Dysentery, Escherichia Coli (E. coli), Hepatitis A&C, Botulism, and Salmonella.

All these are waterborne diseases with Crypto and Giardia tough little critters that need a minimum of a 3 minute rolling boil to kill them off. Boiling will also kill viruses and bacteria.

However, you should consider boiling a first stage treatment and chemical treatments as a safety back up.

I updated my thoughts on water purification in these links:-
Thoughts about water and Water Revisited.

Before people say there is duplication in these posts, yep you are correct.
However I advise you to read both of them.

Note, Those posts are not a definitive guide to water purification and include references to CBRN contamination.

As always you should check out anything I write to ensure I haven’t screwed up in some way, as I am not an expert in anything!
