1. What is the AS/NZS 3500 Water Tank Calculation?

The AS/NZS 3500 standard provides guidelines for water tank sizing in Australia, using a simple formula that multiplies the daily water demand by 1000 to determine the required tank capacity in liters.

2. How Does the Calculator Work?

The calculator uses the AS/NZS 3500 formula:

Where:

• \( Demand \) — Daily water demand in liters
• \( 1000 \) — Multiplication factor per Australian standards

Explanation: This formula ensures adequate water storage capacity based on daily consumption requirements as specified in Australian water standards.

3. Importance of Water Tank Sizing

Details: Proper water tank sizing is crucial for ensuring sufficient water supply, meeting regulatory requirements, and optimizing water storage efficiency in Australian residential and commercial properties.

4. Using the Calculator

Tips: Enter daily water demand in liters. The value must be a positive number representing your estimated daily water consumption.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 1000 in the calculation?
A: The factor of 1000 is specified in AS/NZS 3500 standards to convert daily demand into appropriate tank capacity while accounting for storage requirements and safety margins.

Q2: What factors affect daily water demand?
A: Household size, appliance usage, gardening needs, and local climate conditions all influence daily water consumption patterns.

Q3: Is this calculation suitable for all Australian regions?
A: While based on national standards, local regulations and specific site conditions may require additional considerations in some regions.

Q4: Can this calculator be used for commercial properties?
A: Yes, the AS/NZS 3500 standards apply to both residential and commercial water tank sizing calculations.

Q5: How often should water tank capacity be recalculated?
A: Reassessment is recommended when there are changes in water usage patterns, property expansions, or updates to local water regulations.
