REPAIR OF PUMP FOR WELL 113 <br /> By: John Nelson, Public Works Utilities Lead Person <br /> <br />Background: <br /> <br />Constructed in 1997, Well #3, which produces about 1600 gpm is the largest water producing <br />well in Ramsey. Recently it was observed that during start-up the 125 hp motor seemed to labor <br />excessively for approximately 30 seconds before operating speed was obtained. Staff had an <br />electrician test the draw amperage the pump motor was pulling and found rather than the <br />expected 200 amps and actual pull of 420 amps. <br /> <br />Staffcontacted EH Rennet and explained the problem. A service technician made a field analysis <br />and determined that beari.ng failure and impeller drag may cause the excessive amperage pull. <br />The technician also commented that it common for a well pump which produces the volume of <br />water such as well #3 has for 8 years to have these types of repairs needed. <br /> <br />Staff asked for a worst case estimate for repairs. That estimate totals $18,772 (Enclosed) <br /> <br />This case was approved through the Public Works Committee on February 21, 2006 and <br />recommended to go to full council the next meeting for ratification. <br /> <br />Funding: <br /> <br />As part of the water utility, this repair would be charged to enterprise fund #9601 and cost center <br />6315 (Professional Services). 2006 budget has $60,000 in this line item. <br /> <br />Staff Recommendation: <br /> <br />Contract EH Rennet to make repairs to Well Pump #3 at a cost not to exceed $19,000. <br /> <br />Council Action: <br /> <br />Motion to accept the Public Works Committee's recommendation. <br /> <br />Reviewed By: <br />City Administrator <br />Finance Director <br />Asst PW Director <br />Public Works Utilities Leadperson <br /> <br />CC 2/28/2006 <br /> <br />-5- <br /> <br /> <br />
