MEMORANDUM <br /> DATE e March 13 , 1987 <br /> TO = David Childs , City Manager <br /> F ROM : Larry Hamer, Public Works Director <br /> Z TEM = Reconditioning Well #5 <br /> I am recommending Well #5 be changed to an electric motor with an <br /> angle drive. The City' s Caterpiller engine, which runs on <br /> natural or propane gas would be the backup. <br /> History <br /> Well #5 has always been a good water source, pumping from the <br /> Jordan/Sandstone. The pump is in good condition and is <br /> overhauled about every five years. Until recent years, Well #5 <br /> was used only as a backup in case one of the other .wells went out <br /> of commission or water demands were up. <br /> The Caterpiller engine is not used as a lead source for pumping <br /> because it cannot be relied on for a season or more and the <br /> system is not filtered but is pumped directly into the <br /> distribution system. <br /> In 1987-88 the water system will be transmitted to the filter <br /> plant for treatment, which means Well #5 should also be changed <br /> so we can use it in a lead position when it is needed. <br /> NSP has indicated there will be no charge for the power service <br /> line. A new control panel will cost $5 , 400; a 150 hp motor, gear <br /> drive, labor, etc. , approximately $14,000 ; electrical hook up <br /> will cost about $4, 000, as did Well #4 . <br /> I would like to suggest that the City purchase an energy <br /> efficient motor so that we will be eligible for an NSP rebate and <br /> discount for electrical use. We should also put this well on <br /> interruptible service so we can turn off the power if NSP would <br /> need it. In this case, we could use the gas backup and would <br /> then save about $300 per month on the power cost to run the well. <br /> I recommend we purchase the control panel from the 1987 budget <br /> and the electrical and motor should be included in the 1988 <br /> budget. <br /> LH:cjk <br />
