You need enough water storage to provide 1 gallon of water per person per day for at least 2 weeks.
To determine the exact amount of water storage you need, calculate it based on the number of people in your household and the duration of the storage period (ideally, two weeks or longer). Here's a step-by-step breakdown:
Calculating Your Water Storage Needs:
-
Determine the Number of People: Count the number of people who will be relying on the stored water. This includes all household members and any dependents.
-
Calculate Daily Water Needs: Multiply the number of people by 1 gallon (the recommended daily amount per person).
- Example: For a family of 4, the daily water need is 4 people * 1 gallon/person = 4 gallons.
-
Determine Storage Duration: Decide how long you want your water supply to last. A minimum of two weeks (14 days) is recommended by the Department of Environmental Quality, Division of Drinking Water.
-
Calculate Total Water Storage: Multiply the daily water needs by the number of days you want to be covered.
- Example: For a family of 4 storing water for 14 days, the total water storage needed is 4 gallons/day * 14 days = 56 gallons.
Summary:
| Step | Calculation | Example (Family of 4, 14 days) |
|---|---|---|
| 1. Number of People | Number of household members | 4 |
| 2. Daily Water Needs (per day) | Number of People * 1 gallon/person | 4 gallons |
| 3. Storage Duration | Number of days you want water stored | 14 days |
| 4. Total Water Storage | Daily Water Needs * Storage Duration | 56 gallons |
Additional Considerations:
- Pets: Don't forget to include water for your pets! The amount will vary depending on the size and type of animal.
- Climate: If you live in a hot climate, consider storing extra water, as your needs might be higher.
- Contamination: Assume stored water could be contaminated. Having extra ensures you can use some for hygiene if necessary.
- Storage Containers: Use food-grade containers designed for water storage. Avoid containers that have previously held chemicals.
- Rotation: Rotate your stored water every six months to a year to maintain its freshness.
By following these steps, you can accurately calculate the amount of water storage you need to prepare for emergencies and ensure your family's well-being.
