Water Tank Capacity Formula:
| From: | To: |
Water tank calculation for residential buildings determines the appropriate storage capacity needed to meet the water demands of occupants. Proper sizing ensures adequate water supply while avoiding unnecessary costs for oversized tanks.
The calculator uses the formula:
Where:
Explanation: The formula calculates the total water storage needed by multiplying the number of residents by their daily water usage and the number of days the supply should last.
Details: Correct water tank sizing is crucial for ensuring adequate water supply during normal use and emergencies, optimizing space utilization, and minimizing construction costs while meeting building codes and regulations.
Tips: Enter the number of residents, average daily water usage per person (typically 100-200 liters), and the desired number of days the water supply should last. All values must be positive numbers.
Q1: What is the typical daily water usage per person?
A: Average consumption ranges from 100-200 liters per person per day, depending on lifestyle, appliances, and conservation practices.
Q2: How many days of supply should I plan for?
A: Typically 1-3 days for normal use, but consider 7-14 days for areas with intermittent water supply or emergency preparedness.
Q3: Should I include additional capacity for other uses?
A: Yes, consider adding 10-20% extra capacity for gardening, cleaning, or unexpected increased usage.
Q4: Does this calculation include fire protection water?
A: No, fire protection requirements are separate and typically mandated by local building codes. Consult relevant regulations.
Q5: How does roof area affect rainwater harvesting calculations?
A: For rainwater harvesting, also consider roof catchment area and local rainfall patterns, which may require different calculations.
