Honorable Mayor, City Council, and Staff July 27, 2009 Page 2 Based on these considerations a distribution analysis was conducted for the water users in St. Anthony. This analysis included the following: The yellow graph on the distribution table represents the dry weather water usage between January and March. This distribution will not include lawn watering, car washing, pool filling, or other water intensive activities that occur during the summer months. This graph can be established as the base water usage for day to day activities in each home. 2. The pink or purple graph to the right represents the summer usage or high water usage quarter in the year, July through September. The difference between the summer and winter usage reflects the greatest potential for water conservation through reduction in water intensive activities such as those previously mentioned. 3. The blue graph in the middle represents the average annual water usage. It is anticipated that in future years, after implementation of the tier structure that this graph will move to the left, which will represent conservation efforts by residents and businesses. The proposed tier structure for the water utility is Minimum Bill — (up to 7,500 gallons) the minimum bill in St. Anthony, which is based on the anticipated cost of the City to provide potable water to residents will be maintained at the current level of 7,500 gallons per quarter. Tier I — (7,501 — 15,000 gallons) captures more than the 90th percentile of customers in St. Anthony during dry weather consumption. This Tier break point is proposed to address the concerns about fairness and size of families. Nearly all households are contained within this tier. Tier II — (15,001 — 22,500 gallons) reflects the average annual usage in St. Anthony and is the middle ground between the low and high water demand quarters of the year. It is anticipated, that with some effort and conservation that most homes could achieve this goal of reduction during the summer, high water demand period. This offers encouragement to conserve to this level to avoid the next tier. Tier III — (22,501 — 30,000 gallons) captures most homeowners in the summer high use quarter when conservation measures are most easily implemented as previously mentioned. Establishing this as the third tier will provide significant encouragement for conscious conservation of potable water. Currently the City has no restrictions for summer water usage and it is believed that conservation will be possible by residents to reduce water usage to Tier II or even Tier I status with some effort.
