This group was selected to <br />try and approximate cities with stand -alone systems with similar age of infrastructure which can have a <br />significant influence on the cost of water and sewer services. <br />It should be noted that broad comparisons only give a cursory look at how one community compares to <br />another. One must also incorporate each City's individual philosophy in funding programs and <br />services. <br />For example, Roseville does NOT utilize assessments to pay for water or sewer infrastructure <br />replacements like many other cities do. Instead we fund infrastructure replacements 100% through the <br />rates. As a result, Roseville's water and sewer rates are inherently higher when compared to a City that <br />uses assessments to pay for improvements. Other influences on the rates include whether or not a <br />community softens its water before sending it on to customers, and the extent in which communities <br />charge higher rates to non - residential customers. <br />The following chart depicts the peer group comparison for combined water base rate and usage rate for <br />a single- family home that uses 18,000 gallons per quarter. <br />2013 Water Charge Comparison <br />� $so - <br />� $60 - <br />� <br />$40 — <br />� <br />G <br />L <br />As is shown in the chart, Roseville's total water charge is the highest in the comparison group. Again, <br />there are numerous circumstances and policy preferences that can lead to varying rates among cities. <br />One of the primary reasons why Roseville's water rates are higher is due to the significant increase in <br />infrastructure replacements, which unlike many other cities are funded solely by the rates. <br />The following chart depicts the peer group comparison for combined sewer base rate and usage rate for <br />a single- family home that uses 15,000 gallons per quarter. <br />Page 7of10 <br />
