4. View results — Get a daily, monthly, and yearly water consumption breakdown in liters/gallons.

5. Download/print report — For tracking or sharing with sustainability programs.

Features of the Tool

• Activity-based breakdown — Showering, laundry, cooking, gardening, appliances, leaks.

• Customizable settings — Choose flow rates, cycle durations, household size.

• Unit flexibility — Display results in liters, gallons, or cubic meters.

• Graphical insights — Pie charts showing % water use by activity.

Example Calculation

• Shower: 10 minutes × 9 liters/minute × 2 people = 180 liters/day

• Toilet: 5 flushes × 6 liters × 3 people = 90 liters/day

• Laundry: 3 loads/week × 50 liters/load = ~21 liters/day

• Dishwasher: 5 cycles/week × 12 liters/cycle = ~9 liters/day

• Garden: 15 minutes × 15 liters/minute = 225 liters/week (~32 liters/day)

Estimated Total = ~332 liters/day (per household)
