On February 14, 2012 the City Council <br /> accepted the low quote from Bergerson Caswell and authorized up to $40,000 for each well. <br /> Financial Impact: The City Council authorized expenditures up to $40,000 for each well, and if any of <br /> the final cost exceeds $40,000 we will report back to the Council for further authorization. <br /> Explanation: The purpose of this item is to proceed with routine maintenance and repair work on Well <br /> 5 and Well 12. The majority of the work consists of pulling the well pump, inspecting it, replacing <br /> worn and corroded parts and reinstalling the pumps. We perform maintenance on wells at least once <br /> every ten years or every one billion gallons pumped, whichever is first. <br /> Well 5 is located at 3001 5th Street NW and has produced 960 million gallons since it was last serviced <br /> in April of 2005. Well 5 is part of the off site Twin Cities Army Ammunition Plant (TCAAP) <br /> groundwater remediation system. <br /> Well 12 is located at 2400 Mississippi Street and has produced 91 million gallons since it was last <br /> serviced in March of 2002. Well 12 is one of the City's backup wells. <br /> A well drawdown transducer will also be installed in Well 12 to measure the aquifer water level <br /> automatically. This information is reported to the Minnesota Department of Natural resources each year <br /> as part of our water appropriation permit to pump waters of the state. The current drawdown <br /> measurement is done with a manually read air line. With each well maintenance period, these air lines <br /> need to be replaced. The drawdown transducer will last longer, be more accurate and not require an <br /> operator to be in the well house to take the water level reading. <br /> Costs and Funding: The cost for the maintenance work on Well 5 will be paid from the Army 20 year <br /> operation and maintenance fund. The cost for the maintenance work and installation of drawdown <br /> transducers on Well 12 will be paid from the Water Utility fund. <br /> Grant M. yffels, . . <br /> Director of Public Works <br /> Attachments <br />
