1. What is a Commercial Water Usage Calculator?

Definition: This calculator estimates daily water usage for commercial facilities based on number of employees and process water requirements.

Purpose: It helps businesses and facility managers estimate water consumption for planning, sustainability, and cost management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Usage — Total water usage (gallons per day)
• Employees — Number of employees
• 15 — Estimated gallons per employee per day (restrooms, breakrooms, etc.)
• Process Use — Additional water needed for business operations (manufacturing, cleaning, etc.)

Explanation: The formula accounts for both employee-related water use and operational water requirements.

3. Importance of Water Usage Calculation

Details: Accurate water usage estimates help with utility budgeting, sustainability planning, and identifying conservation opportunities.

4. Using the Calculator

Tips: Enter the number of employees and any additional process water needs in gallons per day. Both values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

A: This is an industry standard estimate for basic employee needs (restrooms, handwashing, drinking water).

Q2: What counts as process water use?
A: Any water used in operations - manufacturing, cleaning, landscaping, kitchen operations, etc.

Q3: Should I adjust the per-employee value?
A: Yes, if your business has higher water needs (e.g., restaurants might use 25 gal/employee).

Q4: How accurate is this estimate?
A: It provides a baseline. For precise numbers, monitor actual water meter readings.

Q5: Does this include outdoor water use?
