Treat microbiological risks in collected fresh water using a lidded camping pot and controlled boiling.
- 1Assess raw water; avoid chemical/salt contamination
- 2One documented treatment sequence
- 3Observe full time, clarity and equipment limits
- 4Protected clean storage and a backup supply
Site and operating requirements
- Identify intended use and likely biological, chemical and salt contamination before choosing treatment. Obtain suitable water testing.
- Keep raw-water and treated-water containers, tools and hands separate. Use clean covered storage.
Tools and measuring equipment
- Timer and route elevation map
- Heat-resistant handling tool
Output and operating conditions
Rolling boil: 1 minute; above 1,981 m elevation, 3 minutes. Cool before drinking.
Public-health method. A 1 L batch and 1.5–2 L pot are practical packing examples, not a treatment-product rating.Parts, quantities and dimensions
| Part | Quantity | Specification / dimensions |
|---|---|---|
| Lidded cooking pot | 1 | Example 1.5–2 L food-contact metal pot for a 1 L batch; leave safe headspace. |
| Outdoor stove and matched fuel | 1 set | Use intact equipment on a level noncombustible surface; follow fuel and windscreen instructions. |
| Raw and treated-water vessels | 2 | Clearly label separate containers; treated-water vessel must tolerate the filling temperature. |
Preparation and component checks
- Confirm local fire restrictions and safe stove instructions.
- Plan carried water if no dependable source exists; boiling does not create water.
Procedure
- 1
Check the route elevation, weather, fuel allowance and a backup drinking-water supply before departure.
- 2
Collect fresh water away from visible contamination; reject suspected chemical or toxic-algae sources.
- 3
If turbid, allow sediment to settle and decant through clean cloth; this clarifies but does not disinfect.
- 4
Heat outdoors. When the entire surface reaches a rolling boil, start the required 1- or 3-minute timer.
- 5
Turn off the stove, fit the clean lid and let the pot cool where it cannot be knocked over.
- 6
Transfer without touching the inside of the clean vessel; close, label and keep separate from untreated water.
Ready-to-use checklist
- Required rolling-boil time completed.
- Water cooled and stored in a clean closed vessel.
Safety and inspection
Boiling does not remove salt, fuels, metals or algal toxins. Use another source if chemical contamination is suspected. Never use a stove inside a tent, vehicle or enclosed shelter.
Verify the result
Time the rolling boil, not the initial heating period. A boiling kettle icon or hot-looking water is not a completed treatment.
Measurement log
- Source, elevation, batch volume and boil time.
- Fuel used and remaining emergency water.
Maintenance and repeat checks
- Inspect fuel connections and pot handles before each trip; replace damaged items.
- Wash and dry vessels after the trip; never return a dirty collection hose to the treated-water container.
Troubleshooting
- Flow/cycle outside the documented range or failed test
- Do not use the output for drinking. Recheck raw-water quality, batch volume, seals/media/device status and the complete source instructions. Retest after correction.
