Staff <br /> has also spoken with SEH regarding possible replacement of the existing pumps and motors. These pumps, <br /> motors and starters have never been replace since their origin in 1971. At this time, the booster pumps are <br /> utilized to supply additional water when the demand exceeds the pumping capacity of one well and operate . <br /> during periods of interruptible electrical service. The pumps may cycle on and off numerous times throughout <br /> the day, creating a high demand charge. Staff is proposing to change out both high service pumps with <br /> Variable Frequency Drive (VFD) motors which will operate more efficiently. <br /> IlkISP offers a program that will pay for 50% of the engineering expenses for this type of energy retrofit. At this <br /> time the estimated cost of the engineering study is approximately $6,500 to $7,000. Staff request Council <br /> approval to proceed with the study. Dependant upon the results of the study, staff would report back to <br /> Council with a request to proceed this year, or budget for the project in 1997. Staff request funding for this <br /> study from the Water Contingency Account 700-4123-910, transferred to the Professional Services account <br /> 700-4123-303. <br /> There are more details to this report that staff will convey to Council at the work session. <br /> Z <br /> Michael Ulrich, Director of Public Works <br /> 'RECOMMENDATION: <br /> 0erprove engineering study for pump, motor and starter replacement and electrical upgrade at the Booster <br /> tion funded by a transfer of $3500 from the Water Contingency Account 700-4123-910 to the Professional <br /> vices Account 700-4123-303. <br />
