139 140 The average overall usage for single-family homes in the wintertime has remained largely unchanged 141 since 2007 with a variance of only 1,000 gallons from year to year. During this same period, the water 142 usage fee initially increased, then declined, and then increased again. 143 144 On the surface, the data suggests that customer behavior and consumption patterns were not influenced 145 by changes in the water usage fees in either direction. This may have occurred because the financial 146 incentive or penalty to modify a household's behavior was not large enough. Then again, it could mean 147 that most households simply held to an established standard of personal hygiene, cleanliness, etc. 148 149 This seems to be evidenced when the water usage fee dropped from $2.35 per thousand gallons in 2008 150 to $1.85 in 2009 as part of an overall rate structure change. This effectively lowered the cost of 151 consumption by 20%. Despite these favorable circumstances, household usage remained unchanged. 152 153 Finally, we can look at the average quarterly summertime usage for single-family homes. 154 SF Homes: Avg Water Usage/Captured April - September 45 40 35 30 25 20 15 10 5 2008 2009 2010 2011 2012 2013 2014 2015 ■ Avg.
