The Emergency Water Calculator is a practical tool designed to help individuals and households determine how much water they will need to store for an emergency. Whether due to natural disasters, power outages, or other emergencies, having an adequate water supply is crucial for survival. This calculator estimates the total amount of water required to sustain a group of people for a set period, ensuring that everyone in your household or group remains hydrated and has access to water for essential needs like cooking, hygiene, and sanitation.
In emergencies, water consumption can increase due to stress, physical exertion, and the need for cleanliness. This calculator helps you plan and prepare for these situations by providing an accurate estimate of the necessary water supply.
Formula of Emergency Water Calculator
The formula for calculating the amount of water needed for an emergency is:
Water Supply Needed = Number of People × Water per Person per Day × Number of Days
Where:
- Number of People is the number of individuals in your household or group.
- Water per Person per Day is the average amount of water required for each person. This is typically 1 gallon (3.8 liters) per person per day, as recommended by health authorities for basic hydration and sanitation needs.
- Number of Days is the duration for which you want to have water supplies available, often ranging from 3 days to 2 weeks, depending on the type of emergency and how long you anticipate being without regular access to water.
This formula ensures that you calculate the right amount of water for every individual in your household and how long you want to cover during an emergency.

Example of Emergency Water Calculator
Let’s go through an example to see how the Emergency Water Calculator works.
Scenario:
- Number of People = 4 (2 adults, 2 children)
- Water per Person per Day = 1 gallon (3.8 liters) per person
- Number of Days = 5 days
Using the formula:
Water Supply Needed = Number of People × Water per Person per Day × Number of Days
Water Supply Needed = 4 × 1 × 5 = 20 gallons
In this case, you would need 20 gallons (76 liters) of water to sustain 4 people for 5 days in an emergency.
If you are using metric units, this would be:
Water Supply Needed = 4 × 3.8 × 5
Water Supply Needed = 76 liters
This example shows how to calculate the water required for a specific situation, giving you a clear goal for water storage during emergencies.
