CASE #1 <br /> <br /> REPAIR OF PUMP FOR WELL #3 <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 <br />producing well in Ramsey. Recently it was observed that during start-up the 125 hp <br />motor seemed to labor excessively for approximately 30 seconds before operating speed <br />was obtained. Staff had an electrician test the draw amperage the pump motor was <br />pulling and found rather than the expected 200 amps and actual pull of 420 amps. <br /> <br />Staff contacted EH Rermer and explained the problem. A service technician made a field <br />analysis and determined that bearing failure and impeller drag may cause the excessive <br />amperage pull. The technician also commented that it's common for a well pump which <br />produces the volume of water such as well #3 has for 8 years to have these types of <br />repairs needed. <br /> <br />Staff asked for a worst case estimate for repairs. That estimate totals $18,772 (enclosed). <br /> <br />Funding: <br /> <br />As part of the water utility, this repair would be charged to enterprise fund #9601 and <br />cost center 6315 (Professional Services). 2006 budget has $60,000 in this line item. <br /> <br />Staff Recommendation: <br /> <br />Contract EH Renner to make repairs to Well Pump #3 at a cost not to exceed $19,000. <br /> <br />Committee Action: <br /> <br />Motion to accept/reject Staff's recommendation and forward to City Council for <br />approval. <br /> <br />Reviewed By: <br />City Administrator <br />Finance Director <br />Asst PW Director <br />Public Works Utilities Leadperson <br /> <br />PW: 2/21/2006 <br /> <br /> <br />
