Water Storage Tank Size Formula:
| From: | To: |
Water storage tank size calculation determines the required capacity of a water storage tank based on daily water demand and the number of days the supply needs to be stored. This ensures adequate water availability during periods of low supply or high demand.
The calculator uses the simple formula:
Where:
Explanation: The calculation multiplies the daily water requirement by the number of storage days needed to determine the total storage capacity required.
Details: Proper tank sizing is crucial for ensuring reliable water supply, preventing shortages during dry periods, optimizing storage costs, and maintaining water quality through appropriate turnover rates.
Tips: Enter daily water demand in liters per day and the number of storage days required. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What factors should be considered besides daily demand?
A: Consider peak usage periods, safety margins for unexpected demand increases, evaporation losses, and future expansion needs.
Q2: How does climate affect water storage tank sizing?
A: In areas with seasonal rainfall variations, larger storage capacity may be needed to cover extended dry periods.
Q3: What's the typical range for storage days?
A: Storage periods typically range from 1-7 days for municipal systems, but may extend to 30+ days for remote or drought-prone areas.
Q4: Should I include fire storage requirements?
A: For commercial and industrial applications, fire storage requirements must be added to the domestic water storage calculation.
Q5: How does tank shape affect capacity calculations?
A: While capacity is measured in volume, tank shape affects available space and may require adjustments for practical installation.
