Water Tank Size Formula:
| From: | To: |
Water tank sizing is the process of determining the appropriate capacity for a water storage tank based on household needs, daily water consumption, and desired days of supply. Proper sizing ensures adequate water availability while avoiding unnecessary costs for oversized tanks.
The calculator uses the water tank size formula:
Where:
Explanation: The formula calculates the total water requirement by multiplying the number of people by their daily water usage and the number of days the supply should last.
Details: Correct water tank sizing is essential for ensuring adequate water supply during shortages, optimizing space utilization, managing costs effectively, and maintaining water quality by preventing stagnation in oversized tanks.
Tips: Enter the number of people in your household, estimate daily water usage per person (typically 100-200 liters), and specify how many days of supply you want. All values must be positive numbers.
Q1: What is the average daily water usage per person?
A: The average ranges from 100-200 liters per person per day, depending on lifestyle, appliances, and conservation practices.
Q2: Should I add a safety margin to the calculated size?
A: Yes, it's recommended to add 10-20% to the calculated size to account for unexpected increased usage or longer periods between refills.
Q3: How does climate affect water tank sizing?
A: In hotter climates or during dry seasons, water consumption typically increases, so you may need to size up your tank accordingly.
Q4: What about outdoor water usage?
A: If you use significant water for gardening, pools, or other outdoor purposes, you should include this in your daily usage calculation.
Q5: How often should I clean my water tank?
A: Water tanks should be cleaned at least annually to prevent sediment buildup and maintain water quality, regardless of size.
