T O : Mayor and Councilmembers <br /> FROM : <br /> Larry Harper, Public Works Director <br /> I TEM : Well #5 Conversion <br /> I propose the City convert Well #5 over to electric power with the capability of.. :running <br /> on natural and propane gas. <br /> The conversion can be done from monies out of the 1988 budget at the same cost for the <br /> Well #4 conversion ($23,000). <br /> NSP informed me that they will run the power to Well #5 (150 hp motor) over with trans- <br /> former at no cost. <br /> RECOMMENDATIONS <br /> Recommend the City purchase the Nema, size 412. furnace pump-control , Model .87RF362MNA, <br /> 480 volt out of the 1987 budget. We were able to save on the Well #4 conversion <br /> and have enough money to get the control panel for Well #5. $23,500 was budgeted <br /> Znd $17,917.94 has been used for the conversion. The remaining $5,582.06 could be used <br /> o purchase the control panel for Well #5. We expect an additional $23,000 to be <br /> required 'in 1988 to complete this project. <br /> COMMENTS <br /> If Well #5 is converted, the City will be able to rely on it for first run operation. <br /> Also, the motor is energy efficient; there is a rebate, and lower pumping rates. <br /> According to NSP, Well #5 could be registered as an interruptable well . This would mean <br /> the well could be pumped on gas or propane for a short duration which would result <br /> in a power rate decrease. <br /> The City needs all of the wells in the- first run operation in order to meet the demands. <br /> Two quotations have been received for the panel . I recommend we accept the lowest <br /> quotation from Layne Minnesota for $5,300. <br /> :cjk6.3.87 <br />
