Water purification is a crucial aspect of disaster management, especially during emergencies when natural disasters like floods, earthquakes, or cyclones disrupt safe water supplies. Access to clean water is essential to prevent waterborne diseases such as cholera, dysentery, and typhoid, which can escalate quickly in disaster-affected areas. Various methods of water purification are applied depending on the availability of resources, the scale of need, and the type of contamination. One of the most common methods is boiling, which involves heating water to a rolling boil for a specific period, typically 5–10 minutes. Boiling effectively kills bacteria, viruses, and protozoa, making it a reliable method in most emergency situations. Its main advantage is that it requires minimal equipment—just a heat source and a container. However, boiling does not remove chemical contaminants or turbidity, so additional steps may be required if the water is heavily polluted. Another widely used method is chemical disinfection. Chemicals like chlorine, chlorine dioxide, or iodine are used to kill pathogens in water. Chlorination is particularly effective and can be applied in small-scale or large-scale settings. Tablets or liquid solutions are commonly used in disaster relief because they
