US Avg: $0.005 / Gallon ($5 per 1,000 Gallons)

How the Calculations Work

Step-by-step breakdown of the underlying equations.

Shower Gallons

G_{\text{shower}} = n_{\text{shower}} \cdot t_{\text{shower}} \cdot 2.1 = 7 \cdot 10 \cdot 2.1 = 147.0\text{ gal/week}

Flush Gallons

G_{\text{flush}} = n_{\text{flush}} \cdot 7 \cdot 1.6 = 5 \cdot 7 \cdot 1.6 = 56.0\text{ gal/week}

Laundry Gallons

G_{\text{laundry}} = n_{\text{laundry}} \cdot 20 = 3 \cdot 20 = 60.0\text{ gal/week}

Weekly Usage (Gallons)

G_{\text{weekly}} = G_{\text{shower}} + G_{\text{flush}} + G_{\text{laundry}} = 147.0 + 56.0 + 60.0 = 263.0\text{ gal/week}

Annual Usage (Gallons)

G_{\text{annual}} = G_{\text{weekly}} \cdot 52 = 263.0 \cdot 52 = 13,676\text{ gal/year}

Annual Cost Impact ($)

C_{\text{annual}} = G_{\text{annual}} \cdot R = 13,676 \cdot \$0.0050 = \$68.38

Variables:

Showers/Week (n_shower): 7
Shower Length (t_shower): 10 mins
Flushes/Day (n_flush): 5
Laundry Loads/Week (n_laundry): 3
Water Utility Rate (R): $0.0050 / Gallon

Annual Water Footprint

13,676

Estimated Annual Cost: $68.38

Conservation Impact

By reducing your shower time by just 2 minutes, you would save 1,528.8 gallons per year.
