Page 2 <br />2/25/91 <br />one of the larger pumps in the booster station in order to reduce major <br />water system pressure changes resulting in surges and low pressures in <br />this area. Based on our discussions with both consultants, we conclude <br />that the variable speed drive installation will not increase pressures <br />in the system nor cause any additional watermain break problems. The <br />variable speed system will, hopefully, reduce some instances of <br />watermain breakage because of the reduced surges in the system that <br />result when the large pumps are turned on and off. Also, the variable <br />speed drive will increase system efficiency resulting in lower electric <br />power costs. <br />Policy Objectives: The capital improvements suggested are contained in <br />the five -year Capital Improvement Program which the council approved in <br />December, 1990. Also, the proposed expenditures for 1991 have been <br />included in the council approved 1991 operating budgets for the sanitary <br />sewer and water utilities. Sanitary sewer and water utilities are <br />enterprise funds. Capital improvements are to be financed by user -fees <br />and not general fund tax revenues. <br />Financial Implications: As noted earlier, these items are included in <br />both the 1991 through 1995 utility Capital Improvement Program as well <br />as the 1991 operating budgets for the sanitary sewer and water <br />departments. The total construction costs for the recommended items are <br />listed. <br />Staff Recommendation: We recommend the council formally approve the <br />feasibility reports, order the projects, and direct the preparation of <br />plans and specifications for the listed improvements. Upon completion <br />of plans and specifications by our consultant, TKDA, we will present the <br />plans to the council for approval prior to bidding. We expect the plan <br />preparation process to take approximately 60 days: <br />Schedule: The work session agenda item detailed the proposed schedule <br />for these projects. If the council orders the preparation of plans and <br />specifications at the February 25, 1991, meeting, we anticipate <br />receiving bids in early May and completing the project by late fall. <br />COUNCIL ACTION: <br />Adoption of a resolution approving feasibility studies and ordering <br />listed improvements and preparation of plans for utility system capital <br />improvement projects as listed. <br />
