F. W ASTEW A TER SYSTEM Capital Improvements for the wastewater system were identified in the same malll1er as the water system: the City's current five-year Capital Improvements Plan, known areas of potential development and capacity needed to serve the proposed future growth. The SUE growth in the wastewater service area is projected at approximately 28% over the next ten-years. Identified improvements include new interceptor mains lift stations and force mains. The additional 14,800 persons projected for the water service area will increase the average day flow by 1.7 million gallons per day (MOD), the maximum month flow by 2.2 MGD and the peak hour flow by 4.4 MOD. These values were determined using the historical per capita use from Table 6 below. Existing and proposed facilities were reviewed on this basis of demand. Table No.6 Basis of Demand for Wastewater System Analysis A verage Day 115 gallons/day Treatment Plant Maximum Month 150 gallons/day Treatment Plant Maximum Hour 300 gallons/day Collection System Peak Dry Weather (PDW) 225 gallons/day Collection System Peak Wet Weather = PDW + 225 gallons/day + III 1&1 Exhibit 4 shows the recommended system improvements required over the next ten-years for the wastewater service area and Table 7 itemizes each project and the project cost. These recommended improvements form the basis for the Wastewater System Impact Fee calculation. The total cost for the wastewater system projects including financing is approximately 84 million dollars. The utilized capacity costs are a ratio of the total project costs based upon the percent of capacity utilized during the ten-year impact fee period from 2002 to 2012. The utilized capacity cost for the recommended improvements is approximately 19.9 million dollars. Utilized costs for existing facilities with excess capacity were not included in the analysis. A Wastewater Master Plan is currently planned for the next fiscal year, which will provide a more detailed analysis of facilities required for new development and their utilized capacities. The recommendation of this report is that the C.I.P. and impact fee analysis be updated based upon the more detailed information within the next two years.
