Y OF Agenda Section: <br /> REQUEST FOR COUNCIL CONSIDERATION Report Number: <br /> oOM Report Date: 5-12-95 <br /> STAFF REPORT Council Action: <br /> 1117198 <br /> IMIi D Special Order of Business <br /> CITY COUNCIL MEETING DATE June 12, 1995 ❑ Public Hearings <br /> 0 Consent Agenda <br /> X❑ Council Business <br /> Item Description: <br /> Replacement o -=Well pump motor starters <br /> Administrator's Review/Recommendation: ink <br /> - No comments to supplement this repo <br /> - Comments attached. <br /> Explanation/Summary (attach supplement sheets as necessary.) <br /> SUMMARY; <br /> At a Council work session in the recent past, staff presented information <br /> related to the well pumps, in regards to improving their electrical and <br /> operational efficiency. Staff has began to research several options <br /> presented by NSP and their findings as to the pump motors efficiencies . The <br /> specific need to research the motor starters originally was to replace the <br /> old equipment with energy efficient mechanisms . <br /> The need for replacement of the starters has now become a necessity. The <br /> starter contacts at Wells 5 and 6 have been deteriorating rapidly, to the <br /> point where the wells have failed. These failures not only cause numerous <br /> callouts, electrical contractor repairs, and possible water shortages . The <br /> contacts have been replaced once to staff' s knowledge . Replacement costs <br /> approximately 12 to 15 years ago were $3 , 000 for each location. At that <br /> time staff kept the old contacts for salvage to use in an emergency. <br /> Earlier this spring the contacts failed at well 5 . They were replaced with <br /> the contacts from well 4 , rendering it inoperable. Last week, well 6 which <br /> has been very reliable, failed due to contact wear. Staff cleaned up the <br /> last of the remaining used salvaged contacts, and was able to start well <br /> six. All contacts previously on hand, that were replaced because they were <br /> unreliable in the past, are now installed, and in use at two of the City' s <br /> main supplies of water. If one of these contacts were to fail, the City no <br /> longer has any worn out replacement parts . <br /> Past history has proven that these contacts are unreliable and badly worn, <br /> one or both of these mechanisms will fail in the near future, which will <br /> present the City with an emergency water situation. Replacement of these <br /> motor controls was recommended in the 1983 Water System CIP, prepared by <br /> then Public Works Director John Johnson. Estimated replacement costs in <br /> 1987 was $12, 000 . <br /> The demand for water is rapidly rising to the peak pumping season. While <br /> staff could utilize others wells, should wells 5 and, or, 6 fail, the City <br /> would be severely penalized by NSP for pumping during Peak Controlled <br /> Periods . <br /> (over) <br /> RECOMMENDATION; <br /> Council authorize staff to solicit quotes for new motor controls for wells <br /> 5 and 6 , and to purchase a new control system should an emergency situation <br /> occur. <br />
