Water Tank Capacity Formula:
| From: | To: |
Water tank capacity per person refers to the amount of water storage required to meet an individual's daily needs for a specified number of days. This calculation is essential for emergency preparedness, off-grid living, and sustainable water management.
The calculator uses the simple formula:
Where:
Example: If a person uses 100 liters per day and needs a 7-day supply, the required tank capacity would be 700 liters per person.
Details: Adequate water storage is crucial for emergency situations, drought preparedness, and ensuring a reliable water supply in areas with intermittent water availability. Proper calculation helps optimize storage capacity while avoiding unnecessary costs.
Tips: Enter your estimated daily water usage per person and the number of days you want the water supply to last. Typical daily usage ranges from 50-150 liters per person depending on lifestyle and conservation practices.
Q1: What is a typical daily water usage per person?
A: Typical usage ranges from 80-120 liters per day for basic needs, but this can vary based on conservation efforts, climate, and personal habits.
Q2: How many storage days should I plan for?
A: For emergency preparedness, 3-7 days is recommended. For off-grid living, consider 14-30 days depending on water availability.
Q3: Does this calculation include water for cooking and sanitation?
A: Yes, the daily usage should include all water needs - drinking, cooking, cleaning, and sanitation.
Q4: Should I add extra capacity for safety?
A: It's recommended to add 10-20% extra capacity to account for unexpected increased usage or extended need.
Q5: How does climate affect water storage needs?
A: Hot climates may require additional water for hydration and cooling, while cold climates might need less but should account for potential freezing.
