Water Purification Options for Long-Term Camps

If there’s one thing you absolutely need when camping for the long haul, it’s clean water. Whether you’re deep in the Cederberg, parked up along the Wild Coast, or embracing total off-grid living, access to safe drinking water is non-negotiable. But lugging litres of bottled water isn’t always practical (or sustainable).

So what’s the solution? Purify your own water. In this guide, I’ll walk you through the best water purification methods for long-term camps — from budget-friendly basics to high-tech filters.

Why You Need to Purify Natural Water Sources

Streams, rivers, and even mountain springs might look clean, but they often carry harmful bacteria, viruses, or parasites like Giardia. Drinking untreated water can lead to serious illness — a real buzzkill for your backcountry bliss.

Risks include:

• Bacterial infections (E. coli, Salmonella)
• Protozoa (Giardia, Cryptosporidium)
• Viruses (Hepatitis A, Norovirus)
• Sediment and chemical contaminants

Purification helps you avoid all of that and makes your camp more self-sufficient.

Overview of Purification vs. Filtration

Pro Tip: The safest setup for long-term camping often combines filtration + purification.

5 Best Water Purification Options for Long-Term Camps

1. Gravity Filters

Example: Platypus GravityWorks, LifeStraw Mission

• Uses gravity to push water through a filter
• No pumping or squeezing
• Ideal for groups or basecamps

Pros: Low effort, filters a lot at once
Cons: Slower setup, parts need regular cleaning

2. Pump Filters

Example: MSR MiniWorks EX, Katadyn Hiker Pro

• Hand-pump water through a ceramic or carbon filter
• Great for on-the-go purification

Pros: Reliable and rugged
Cons: Manual effort, can clog with dirty water

3. UV Light Purifiers

Example: SteriPEN Ultra, CrazyCap

• Uses ultraviolet light to neutralise viruses, bacteria, and protozoa
• Lightweight and quick (90 seconds per bottle)

Pros: Kills viruses, great for clear water
Cons: Needs batteries/power, doesn’t filter sediment

4. Chemical Purification Tablets/Drops

Example: Aquatabs, Katadyn Micropur, iodine drops

• Small, cheap, ultra-portable
• Kill viruses and bacteria with chlorine or iodine

Pros: Lightweight, long shelf life
Cons: Wait time (30+ minutes), chemical taste, no sediment removal

5. Boiling

• The classic method: 1-3 minutes of rolling boil
• Requires heat source and clean container

Pros: No gear needed, kills all pathogens
Cons: Time- and fuel-intensive, no sediment removal

Gear Pairings for Best Results

Combine methods for maximum safety and versatility:

• Gravity filter + UV light = ideal for groups
• Pump filter + tablets = good for multi-day hikes
• Boiling + pre-filter cloth = best for remote, sediment-heavy sources

What I Use on My Trips

For most of my longer camp setups, I rely on a gravity filter for daily use and keep UV and tablets as backups. In the bush, redundancy is everything.

And yes, I still boil water for coffee. Something about it just tastes right.

Purifying your own water isn’t just about safety, it’s about freedom. With the right setup, you can stay longer, go further, and roam wilder.

So next time you plan a remote camping trip, don’t just pack water. Pack a way to make it yours.

Stay wild, stay hydrated.
