Choose a suitable container
Use unopened commercially bottled water or containers designed for food and water storage. A tight lid and a narrow opening or dispensing tap help reduce contact with hands and utensils.
Do not use containers that previously held bleach, pesticides, fuel, or other toxic substances. Consider filled weight before choosing a size: water is heavy, and one large container may be difficult to move safely.
Prepare and store it deliberately
Follow the container manufacturer and current official guidance for cleaning and sanitizing a refillable container. Fill it with safe water, close it tightly, label it as drinking water, and record the storage date.
- 1Inspect the empty container and lid for damage.
- 2Clean and prepare it using current official instructions.
- 3Fill, close, label, and date the container.
- 4Store it in a cool location away from direct sunlight and toxic substances.
- 5Keep a clean method for dispensing water without touching the inside.
