How can I safely store drinking water after purifying or boiling it?
To ensure drinking water remains safe after purification or boiling, it must be stored in suitable, clean containers that protect it from recontamination. It is recommended to use containers made of sturdy plastic, ceramic, or metal, ensuring they have a small opening that can be tightly sealed to prevent the entry of contaminants. Containers should be cleaned and disinfected regularly before each use to ensure the safety of the stored water [4].
Choosing Suitable Water Storage Containers
Choosing the correct containers is a key step in maintaining the purity of drinking water. Containers should be specifically designed for food storage (food-grade) to prevent the transfer of harmful chemicals into the water [5]. It is preferable to use containers with a narrow opening to minimize the potential for water contamination during pouring, and they should ideally have a tight-fitting lid. Avoid using containers that have previously held toxic chemicals, such as bleach, pesticides, or petroleum products, as these materials may leave residues that transfer to the water [4].
Cleaning and Disinfecting Water Storage Containers
Before storing purified or treated water, it is essential to clean and disinfect the containers thoroughly. Start by washing the container with soap and water, then rinse it completely. Afterward, disinfect it using an unscented chlorine bleach solution containing 5% to 9% sodium hypochlorite. The solution can be prepared by mixing 5 ml (one teaspoon) of bleach per liter of water, or 19 ml (4 teaspoons) per gallon of water [4]. Seal the container tightly and shake it well to ensure the disinfecting solution reaches all internal surfaces. Wait at least 30 seconds, then pour out the solution and allow the container to air dry before use, or rinse it with clean, treated water [5].
Safe Storage Practices
To maintain the quality of stored water, certain important practices must be observed. Label the containers clearly as "drinking water" and include the date of treatment or storage. Containers should be stored in a cool place away from direct sunlight [4]. Avoid storing water near toxic substances like gasoline or pesticides to prevent any potential contamination. If you are filling containers at home, it is recommended to change the water every six months [5].
Handling Stored Water
When using stored water, be careful not to contaminate it. Use a clean ladle or another device to remove water from the container each time, and avoid touching the water or the internal parts of the container with your hands. These precautions help prevent introducing germs or contaminants into the clean water [5].
