whether customers are being penalized enough for higher consumption or if they've established a standard consumption for their home no matter the rat, based on the rate fluctuations over that same period. Even when the water rates were lowered by 20% in 2008-2009, Mr. Miller reported that the City had actually seen the reverse happen with more consumption when rates increased. Mr. Miller questioned if that indicated there was not enough incentive offered to conserve water or homeowners were simply not willing to move beyond their established household standards of consumption. Reviewing summertime consumption during that same period, and also factoring in annual rainfall, Mr. Miller noted that aggregate behavior did change when there was more rainfall. While it didn't matter for some homeowners in the amount they ran their sprinkler or irrigation system compared to the amount of rainfall received, Mr. Miller noted in the aggregate it did fluctuate indicating some were making a conscious decision to adjust their sprinkling habits accordingly. However, while indicating more fluctuation in ranges, Mr. Miller questioned if it was statistically significant even though to him it seemed to indicate consumers were adjusting their behavior and consumption accordingly. However, Mr. Miller questioned again if this was due to not enough incentive to conserve or lack of interest in changing established behavior for consumption habits. Specific to water conservation, Mr. Miller noted higher tiers could be created for those deemed higher consumption customers, but noted there were few people fitting into that higher water category. Historically, Mr. Miller reported that most single-family homes in Roseville used 15,000 to 16,000 gallons of water per quarter or less than that. Based on that historical data, Mr. Miller noted that compared to other inner -ring suburb homes, Roseville's consumption was very low; and further noted that the majority of Roseville homes didn't have a built in lawn sprinkler system. While unsure how to make a determination, based on his analysis, Mr. Miller questioned if water rates were even doubled whether it would incent people to use less water. Mr. Miller suggested the most effective step may be to increase education and outreach by providing information to residents on benefits of low volume water devises, and awareness of how little water it actually takes for an established lawn to proactively incent water conservation. Chair Stenlund suggested the number of snowbirds from one winter to the neat may skew data; but Mr. Miller responded that may be, but historically from one year to the neat, his analysis had shown little change in the number of snowbirds each year. Member Seigler noted with a tiered rate structure it may actually erroneously punish households with a lot of kids or even a few kids. Mr. Miller reported that this had been found out in trying the tier system several years ago and difficulty in defining tiers to reward those making an effort to
