Clean drinking water is one of life’s most basic needs, yet it’s something many people take for granted. Whether you’re dealing with poor tap water, travelling to remote areas, or facing an emergency situation, knowing how to purify your water can be a real lifesaver.
Contaminated water may contain harmful bacteria, viruses, parasites, and chemicals. These can lead to serious health problems, especially if consumed regularly or in large quantities. Fortunately, there are several reliable ways to make your water safe to drink. Here are ten essential tips to help you do just that.
1. Boil It
Boiling is one of the simplest and most effective methods of purifying water. By bringing water to a rolling boil for at least one minute (or three minutes at higher altitudes), most pathogens, including bacteria, viruses, and parasites, are destroyed.
While boiling won’t remove chemicals or heavy metals, it’s ideal when you’re unsure of the biological quality of your water. Just allow it to cool before drinking, and store it in a clean container.
2. Use a Water Filter
Water filters come in a variety of forms, including jug filters, under-sink systems, tap-mounted units, and gravity-fed containers. Depending on the type, they can remove sediment, chlorine, bacteria, and even microplastics.
It’s important to choose a filter designed for your specific concerns. For example, some filters focus on improving taste while others aim to eliminate pathogens. Always replace cartridges as recommended to maintain their effectiveness.
3. Try a Portable Purification System
If you’re travelling, hiking, or camping, portable purification systems can be incredibly handy. Options include pump filters, UV sterilisers, and filter straws.
Pump filters typically use ceramic or carbon elements, while UV sterilisers use ultraviolet light to kill microorganisms. Filter straws are ultra-lightweight and allow you to drink straight from a water source while filtering it instantly.
4. Add Water Purification Tablets
Water purification tablets are compact and easy to carry, making them perfect for travel or emergencies. Most contain iodine or chlorine dioxide, which neutralise bacteria, viruses, and some parasites.
Always follow the instructions carefully regarding dosage and wait times. Be aware that some tablets can leave an aftertaste, and they may not be suitable for people with iodine sensitivity.
5. Use UV Light
Ultraviolet light devices such as SteriPENs use UV rays to disrupt the DNA of microorganisms, rendering them harmless. These devices are battery-operated and effective against bacteria, viruses, and protozoa.
They work best with clear water, as cloudy or murky water can block the light and reduce its effectiveness. For best results, pre-filter your water if necessary.
6. Activated Charcoal
Activated charcoal is known for its ability to absorb impurities and improve taste. While it may not kill bacteria or viruses, it can remove chemicals, chlorine, and odours.
Charcoal filters are often built into water jugs or bottles, and can also be made at home in a pinch. This method is best used in conjunction with others, such as boiling or chemical treatment.
7. Solar Disinfection (SODIS)
This method uses the power of the sun to disinfect water using only clear plastic bottles and sunlight. Fill a transparent PET bottle with water and leave it in direct sunlight for six hours (or up to two days in cloudy conditions).
The combination of UV rays and heat kills most harmful microorganisms. It’s a simple and eco-friendly method, though it requires patience and suitable weather.
8. Distillation
Distillation involves boiling water and collecting the steam, which is then condensed back into liquid form. This process removes most contaminants, including heavy metals, salts, and microbes.
Although it’s highly effective, distillation can be time-consuming and requires a heat source and suitable equipment. It’s especially useful when water is suspected to contain chemical pollutants.
9. DIY Sand and Charcoal Filter
In a survival situation, a makeshift filter using layers of gravel, sand, and charcoal can help remove debris and some impurities. Pour water through this layered setup using a bottle or container, and collect it at the bottom.
While this method won’t kill pathogens, it’s a good pre-treatment option before boiling or adding tablets. It also improves the water’s appearance and taste.
10. Always Store Water Safely
Purifying water is only part of the equation. Once clean, it must be stored properly to prevent re-contamination. Use food-grade, BPA-free containers with tight-fitting lids. Keep containers in a cool, dark place and label them clearly with the date.
Avoid dipping unclean hands or utensils into stored water, and clean your containers regularly to keep bacteria at bay.
Conclusion
Purifying your drinking water is not just a useful skill, it’s a crucial one. Whether you’re preparing for a camping trip, dealing with a natural disaster, or simply want safer tap water, these methods can help you stay healthy and hydrated.
Choose the techniques that best suit your needs and environment. For maximum safety, consider combining methods, like filtering followed by boiling or chemical treatment.
