Essential survival skills: The importance of water treatment methods for survival

  • Stored water is unreliable — municipal systems can fail, and stored water has shelf-life and maintenance limitations.
  • Urban scavenging options include draining water heaters, using rain barrels or accessing external faucets with a sillcock key—but supplies are limited.
  • Retention ponds are risky — they often contain pollutants (oil, pesticides ands ewage) requiring rigorous purification (boiling alone isn’t enough).
  • Water treatment methods preppers can employ include boiling, filtration and purification, but layered methods are often necessary.
  • Skills outweigh storage — long-term survival hinges on knowing how to purify water from any source, not just stockpiling.

Most people assume clean water will always flow from their faucets. Yet time and time again, disasters have proven this is not true. Municipal systems are vulnerable to power outages, pipe ruptures or pollution. Even stored water has limits: plastic bottles degrade and water tanks require maintenance.

For survival experts, the message is clear: Relying solely on stored water is insufficient. The ability to locate, purify and conserve water is a fundamental skill that could determine survival in an emergency.

Urban water scavenging

For city dwellers, options shrink fast. You can drain water heaters or toilet tanks, but that will only last you days. Rain barrels can help, but water collection mainly depends on weather. A “sillcock key” can help you access outside faucets around commercial buildings like schools and churches, but these sources are finite.

In extreme situations, you might have to turn to suburban retention ponds. These are permanent constructions meant to hold water flow for a limited duration. But suburban retention ponds are often contaminated with oil, pesticides and sewage, so water from this source demands rigorous purification to be useable. You’re not just going to be filtering bacteria, you’ll also be battling chemicals and heavy metals. Boiling alone won’t cut it.

The key to solving this problem is understanding water treatment methods:

  • Boiling – easiest method for killing microorganisms, such as viruses, bacteria and parasites, in water; does not get rid of chemical contaminants.
  • Filtration – removes visible contaminants (dirt, bacteria) via physical barriers like microporous filters or makeshift sand layers.
  • Purification – kills viruses and neutralizes chemicals through boiling, distillation or UV treatment.

While water filtration removes larger impurities like sediment, purification goes further by eliminating or neutralizing microscopic pathogens. But multiple treatment methods, such as pre-filtering, distilling and chemical treatment, may be necessary to make water truly safe for drinking.

In cases when water is contaminated with biological waste, experts recommend using a disinfectant like iodine or chlorine (or chlorine dioxide) after filtering to kill any remaining viruses and bacteria. Only use fresh, unscented household liquid chlorine bleach that is less than one year old. To disinfect one gallon of water, add six drops of chlorine using a medicine dropper. Two gallons will require 12 drops (about 1/8 teaspoon) and so on.

Making water from suburban retention ponds potable is a labor-intensive process, which is why in a true survival situation, someone will have to be on water duty full-time. The water would’ve to go through pre-filtering multiple times, then boiling or distilling, plus another round of filtering — or possibly more — before it can be used for anything. Having a WAPI (Water Pasteurization Indicator) on hand can make confirming the safety of your treated water much easier.

Mastering water treatment isn’t just practical — it’s indispensable. Equipping yourself with this knowledge ensures you’re prepared when safe water isn’t readily available. Whether you’re stranded in the wild or facing a disaster, mastering these techniques could mean the difference between life and death.

Water storage tips

Federal guidelines recommend storing one gallon of water per person daily — but you’ll find that’s barely enough for drinking and hygiene when SHTF. A family of four needs 120 gallons for a 30-day supply, a volume rarely stockpiled. Preparedness advocates recommend stocking bottled water, adding collapsible jugs and investing in portable water filters and/or purifiers as extra precautions.

But the ultimate solution is skill-building. While storage delays the inevitable, knowing how to make water safe — no matter the source — can ensure your long-term survival. (Related: Prepping basics: Essential tips on how to prepare for a long-term water supply disruption.)
