How to determine my family’s total water storage needs?

Calculating Water Needs

To calculate your family’s total water storage needs, start by multiplying the number of people by the recommended daily water intake of 1 gallon per person. For example, a family of four would need 4 * 1 gallon = 4 gallons per day. Next, consider the number of days you want to be prepared for. A good starting point is 30 days, but this can vary depending on your specific situation. For a 30-day supply, multiply the daily water intake by 30: 4 gallons per day * 30 days = 120 gallons.

Considering Activity Level and Climate

Activity level and climate can greatly impact your family’s water usage. For example, if you have a family member who is physically active or lives in a hot and humid climate, you may need to store more water to account for increased sweating and water loss. In general, you can add 1-2 gallons per day for each additional person who is physically active, and 1-2 gallons per day for each person in a hot and humid climate. For a family of four, this would add an additional 8-16 gallons per day, bringing the total to 12-16 gallons per day.

Determining Storage Capacity

Once you have calculated your family’s total water storage needs, consider the storage capacity of your containers and the space available for storage. A good rule of thumb is to use food-grade plastic containers or water barrels with a capacity of at least 55 gallons. You can also use smaller containers, such as 1-gallon jugs, but be sure to calculate the total capacity and label each container with its contents and date. Be sure to store the containers in a clean, dry area and check the water regularly for taste, odor, and bacterial growth.
