Would You Know Where to Find Safe Drinking Water?
We've all noticed it this summer. Weeks of warm weather and very little rain have left grass brown, rivers running lower than usual and reservoirs under pressure in some parts of the country. It serves as a timely reminder that water is something we often take for granted—until it isn't there.
Whether you're walking in the hills, camping for the weekend, travelling abroad or simply enjoying the outdoors, carrying enough drinking water should always be your first priority.
But what if your plans don't go quite as expected? Could you safely drink from a stream? What about a lake or a river? And what if the water coming from your tap at home suddenly wasn't safe to drink?
Knowing the answers could make all the difference.
Clear Water Doesn't Always Mean Safe Water
One of the biggest misconceptions outdoors is that if water looks clean, it must be safe. Unfortunately, that's not the case. Even crystal-clear streams can contain microscopic bacteria, parasites, viruses or contamination from livestock, wildlife or agricultural run-off further upstream. Water that appears perfectly safe can still make you seriously ill. That's why experienced walkers, campers and travellers never rely on appearance alone.
Where Would You Find Water?
If you found yourself running low on drinking water, some natural sources are better than others.
Natural Springs - Water emerging directly from the ground is generally considered one of the better natural sources. However, unless you know the spring is from a trusted drinking water source, it's still sensible to treat the water before drinking.
Fast Flowing Streams - Moving water is usually preferable to stagnant water, particularly in upland areas where there's less chance of contamination. Even so, bacteria and parasites may still be present, so treatment is always recommended.
Rivers - Although rivers are constantly moving, they collect water from a huge area. Contamination from farms, wildlife and settlements upstream can all affect water quality. Never assume river water is safe without treatment.
Lakes - Lakes may look inviting, especially in hot weather, but still water often provides ideal conditions for bacteria and microorganisms. Always treat lake water before drinking.
Ponds - If possible, avoid drinking from ponds altogether. Stagnant water carries the greatest risk of contamination and should only ever be considered as a last resort.
What About Rainwater?
Fresh rainwater collected directly into a clean container is often one of the safer natural water sources available. Rainwater collected from tents, tarpaulins or clean camping equipment can be useful if you're outdoors for an extended period. Where practical, it's still worth treating before drinking.
Safe Water Isn't Just an Outdoor Skill
When most people think about water filters and purification tablets, they picture backpacking trips, wild camping or overseas adventures.
But they're just as useful much closer to home.
The UK's drinking water supply is among the safest in the world, but occasionally things happen that interrupt it:
- Burst water mains
- Flooding
- Contamination incidents
- Storm damage
- Boil water notices
While these situations are relatively uncommon, they do happen, and they can leave households without access to safe drinking water for hours or even days. Having a way to treat water provides valuable peace of mind should the unexpected occur.
Prepared, Not Paranoid
Emergency preparedness has become increasingly popular in recent years, but it's often misunderstood. Being prepared doesn't mean expecting disaster. It simply means having sensible equipment available should everyday services be disrupted.
Many people now keep a small emergency kit at home containing essentials such as:
- Drinking water
- Water purification tablets
- A portable water filter
- A first aid kit
- Torch and spare batteries
- Portable radio
- Power bank
- Warm clothing
- Long-life food
Hopefully, you'll never need any of it. But if you do, you'll be glad it's there.
Three Ways to Make Water Safer
If you're spending time outdoors—or preparing an emergency kit—there are several simple ways to improve the safety of drinking water.
Water Filters
Portable water filters are ideal for walkers, campers, backpackers and travellers. They're lightweight, easy to carry and remove many harmful bacteria, parasites and sediment from natural water sources, making them an excellent choice when clean drinking water isn't readily available.
Water Purification Tablets
Compact enough to fit into any rucksack or emergency kit, purification tablets provide a simple backup when you're away from treated water supplies. They're particularly useful for travel, expeditions and emergency situations where carrying large quantities of water isn't practical.
Carry Water Whenever You Can
The best solution is always prevention. Plan your route. Carry enough drinking water for the conditions. Know where you can safely refill along the way. And always have a backup method of treating water if circumstances change.
Preparation Gives You Options
Nobody sets off on a walk expecting to run out of water. Equally, nobody expects a burst water main, severe weather or disruption to their local water supply. Preparation isn't about worrying. It's about giving yourself options.
Whether you're hiking through the countryside, camping with the family, travelling overseas or simply preparing for unexpected situations at home, having reliable water treatment equipment means one less thing to worry about.
