Quick Answer
To maintain water quality in long-term storage, regularly inspect containers for signs of contamination, such as rust, mold, or animal invasion. Treat stored water with the proper disinfection methods, and consider storing water in food-grade containers with tight-fitting lids. Proper storage and maintenance can ensure safe drinking water for years to come.
Choosing the Right Containers
When it comes to storing water, the type of container used is crucial. Food-grade containers, such as plastic buckets or glass jugs, are ideal for long-term water storage. Make sure the containers are BPA-free, as this chemical has been linked to health problems. A minimum capacity of 5 gallons per person is recommended for long-term storage, assuming a daily consumption of 1 gallon per person.
Water Treatment and Disinfection
Proper water treatment and disinfection are essential to prevent bacterial growth and contamination. Chlorine bleach is a common disinfectant, with a recommended dosage of 1-2 teaspoons per gallon. However, this method may not be effective against certain pathogens, such as cryptosporidium and giardia. For added protection, consider using a water filter or purification tablets, such as those containing chlorine dioxide or iodine.
Storage and Maintenance
Proper storage and maintenance are critical to maintaining water quality. Store containers in a cool, dry place, away from direct sunlight and potential contaminants. Regularly inspect containers for signs of contamination, such as rust, mold, or animal invasion. Every 6-12 months, treat stored water with the proper disinfection methods and replenish the water supply to maintain a safe and potable water source.
