Drinking Water Supply During a Blackout
In a blackout, fresh drinking water may no longer reach households, as the pumps for water transport have no power. Along with your food supply, ensuring a daily water supply for at least 14 days is probably the most important task in preparing for a blackout.

For each adult in your household, you should have at least a gallon of water per day available for drinking, in addition to water needed for cooking and personal hygiene.
You can create your stock with a combination of bottled water from the supermarket and additional water tanks filled with regular tap water.
If you have access to natural water sources or a pool nearby, you can also use these for water supply. To filter contaminated water, a special drinking bottle with a built-in water filter is recommended, which can be used for easy water purification.

Notes & Usage
Bottled Still Water
The bottled water is intended as pure drinking water to cover the daily requirement of 1 gallon per person.
💡 Tip Water in bottles is not indefinitely shelf-stable. It's best to sort your water stock so that you always consume the oldest bottles in your daily routine and restock them. This way, you automatically rotate your water supply regularly.
Drinking Water in Water Tanks
The water in the tanks is intended for cooking, personal hygiene, and dishwashing - in addition to the drinking water bottles about 1 gallon per person per day. The tanks often have a practical outlet that can be used to dose the water. Tap water in containers is not long-lasting, so it is recommended to add water purification tablets for conservation and protection against bacteria. To make the tap water last longer, 2-3 water purification tablets per gallon of water should be added. With tablets, the water in the tanks is shelf-stable for about 6 months, so it should be replaced regularly.
💡 Tip It's best to label the water tanks with the filling date, so you always know when the water in one of the tanks should be replaced.
