Total Overhead Tank Capacity Required (Minimum)
What this tool does: This calculator estimates the minimum required capacity of an overhead water storage tank for a building based on the number of residents, their average daily water consumption, and the number of days the tank should be able to supply water without refilling.
How this tool works: Users enter the expected number of persons staying in the building, the average water consumption per person per day (in liters), and the desired number of days the tank should maintain supply without refilling. The tool then calculates the total volume of water the overhead tank must hold to support these inputs.
How the calculation works: The calculation is based on the principle of total water demand over the specified period. It multiplies the number of people by their average daily consumption and the number of days for storage.
Underlying formula:
Capacity (liters) = Number of Persons × Average Daily Consumption (liters) × Number of Days
This means if you expect 10 people, each consuming 100 liters daily, and want the tank to last 2 days without refilling, the required tank capacity is:
Capacity = 10 × 100 × 2 = 2000 liters
This calculation ensures sufficient water storage to meet needs during outages or limited supply durations.
