We Americans flush an average of 10 gallons of drinkable water down the toilet every day. That’s 3,650 gallons per person per year. 
In Tucson, a year of flushing sends the equivalent of enough energy to power a 100-watt light bulb for between 450 and 5,550 hours (depending on the toilet and water source) spiraling down the toilet, according to Tucson-based Watershed Management Group. That’s because much of the water we flush down the toilet comes from the Central Arizona Project canal, which pumps water 320 miles uphill
from Lake Havasu on the Colorado River to Phoenix and Tucson.
