1. What is Water Usage Calculation?

Water usage calculation for new builds estimates total water consumption per person per day by summing fixture consumption and adding a base usage value.

2. How Does the Calculator Work?

The calculator uses the water usage formula:

Where:

• \( fixture\_consumption \) — Water consumption from fixtures (l/person/day)
• \( 5 \) — Base water usage (l/person/day)

Explanation: The equation calculates total water usage by combining fixture-specific consumption with a standard base usage value.

3. Importance of Water Usage Calculation

Details: Accurate water usage estimation is crucial for designing efficient plumbing systems, ensuring adequate water supply, and promoting sustainable water management in new building projects.

4. Using the Calculator

Tips: Enter fixture consumption in liters per person per day. The value must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: Why add 5 l/person/day as base usage?
A: The base usage accounts for general water consumption not covered by specific fixtures, such as basic hygiene and miscellaneous uses.

Q2: What are typical fixture consumption values?
A: Typical values vary by fixture type: toilets (4-6 L/flush), showers (7-10 L/min), faucets (5-8 L/min). Consult local standards for specific values.

Q3: How accurate is this calculation?
A: This provides a reasonable estimate for planning purposes. Actual usage may vary based on user behavior, fixture efficiency, and other factors.

Q4: Should this calculation be used for regulatory compliance?
A: While useful for initial planning, always verify with local building codes and water regulations for compliance requirements.

Q5: Can this calculator handle multiple fixtures?
A: The current version requires summed fixture consumption. For detailed multi-fixture calculations, consider specialized hydraulic design software.
