Ensuring access to safe drinking water is essential for good health. Many households in India depend on untreated sources such as wells, borewells, and irregular municipal water supplies. The following are some simple, low-cost, and effective purification methods that citizens can easily use at home to make water safe for drinking. Simple methods for safe drinking water Boiling Boiling is one of the most reliable ways to disinfect water. How to do it: Boil water for 10–12 minutes. Let it cool in a covered container to prevent contamination. Benefits: Kills bacteria, viruses, and parasites. Cloth Filtration Useful for removing visible dirt, sand, and impurities. How to do it: Fold a clean cotton cloth 3–4 times. Pour water through it slowly. Note: Combine with boiling or chlorination for better safety. Solar Disinfection (SODIS) A zero-cost method using sunlight. How to do it: Fill clear PET bottles with water. Keep them under direct sunlight for 6–8 hours. Benefits: UV rays kill most microbes. Alum (Fitkari) Settling Helps improve clarity by settling suspended particles. How to do it: Add 1 gram of alum per litre of water. Stir well and wait 30 minutes. Note: Follow with boiling or filtration. Household Chlorination Recommended during water contamination or emergencies. How to do it: Add 2–3 drops of liquid chlorine (sodium hypochlorite) per litre of water. Wait for 30 minutes before drinking. Benefits: Effective against most germs. DIY Sand–Charcoal Filter A simple home filter for clearer and better-tasting water. How to build: Top layer: Pebbles Middle layer: Charcoal Bottom layer: Clean sand Pour water from the top and collect from the bottom. Note: Combine with boiling for best results. Clay Pot or Ceramic Candle Filters Low-cost traditional filters widely used in rural households. Benefits: Removes sediments Improves taste Keeps water naturally cool Regular cleaning is necessary. Safe Storage Tips Store purified water in clean, covered containers. Do not mix treated and untreated water. Clean storage vessels regularly with soap and warm water. Use glass or steel containers when possible.
