Where’d you get those numbers? — Water Savings
September 1, 2007
A Mechanical, Electircal and Plumbing Engineer developed Water Use Reduction Tables, which calculate average water consumption per residence compared to projected water consumption per South Waterfront residence. The water consumption per residence considers daily use (the number of times a day a specific appliance or convenience uses water), flow rate of water, usage (how the water is used by the appliance or convenience, for example, in water saving mode or standard mode) and the number of occupants to arrive at a daily water usage volume. This daily figure was then annualized.
This annual water usage for SWF was then compared to the national average water use per person per year, multiplied by the same number of occupants. The annual water savings was then equated to number of showers saved per year. The average shower was calculated at 20 gallons of water or 8 minutes of shower time with a 2.5 gallon/minute water flow.
Smartwater.com, npr.org, supplyht.com and the American Water Association were sources for this information.
