WIAll <br /> 11" MEMORANDUM <br /> Memo To :Mayor and Council Members <br /> From :Ric Minetor, City Engineer/Director of Public Works <br /> ?°`.‘6141:± <br /> Date :July 19, 1990 <br /> Subject :Water Treatment Plant #1 Rehabilitation <br /> During the last few weeks, I have discussed the problems and <br /> concerns of attempting to retrofit the existing water treatment <br /> plant building with new equipment. A primary concern is the <br /> inability to ever expand the capacity of the plant if we do <br /> retrofit the existing building. <br /> John Stodola of Short-Elliott-Hendrickson, Inc. , the consulting <br /> engineer for this project, has prepared a preliminary plan and <br /> cost estimate for construction of a new water treatment plant <br /> building at the intersection of Bronson Drive and Edgewood Drive <br /> (the existing well #3 site) . The proposed building would house <br /> well #3 and the new treatment equipment. Expansion of the plant <br /> capacity would be allowed by expansion of the building in the <br /> future , if the expansion is needed. The building would be <br /> . constructed with tilt-up concrete wall panels for cost savings. <br /> The estimated increase in cost due to the new building is <br /> approximately $360,000. <br /> The impact to future water rates was addressed by Don Brager, <br /> Finance Director, in a previous memo. The future rates would <br /> require additional 5 cent per 1,000 gallons increases in 1992, <br /> 1993 , and 1994. Over the 5 year period, the annual rate of <br /> increase would be 7% instead of the 6% estimated during the rate <br /> study. <br /> There are some additional issues that could result in other <br /> increases in the project budget. The primary concern is whether <br /> the State Fire Marshal requires air scrubber systems on the <br /> chemical rooms. This issue' will be addressed with the State Fire <br /> Marshal in a future meeting. Any additional costs will be handled <br /> by reducing the projects covered by the bond issue rather than by <br /> increasing the bond issue. The projects eliminated would then be <br /> scheduled to be financed at a future date through regular capital <br /> expenditures in the water system. The projects that could be <br /> affected are the redevelopment of well #4 , if feasible; the <br /> transmission main from well #4 , and the TH 10 water main <br /> crossing. <br /> S <br />
