Explanation/Summary(attach supplement sheets as necessary) Summary: In an effort to continue to enhance the efficiency and performance of the City's Water system, staff has been consulting with representatives from NSP regarding electrical rates and upgrades for the Booster Station. Staff has also spoken with SEH regarding possible replacement of the existing pumps and motors. These pumps, motors and starters have never been replace since their origin in 1971. At this time, the booster pumps are utilized to supply additional water when the demand exceeds the pumping capacity of one well and operate . during periods of interruptible electrical service. The pumps may cycle on and off numerous times throughout the day, creating a high demand charge. Staff is proposing to change out both high service pumps with Variable Frequency Drive (VFD) motors which will operate more efficiently. ---,;RVSP offers a program that will pay for 50% of the engineering expenses for this type of energy retrofit. At this time the estimated cost of the engineering study is approximately $6,500 to $7,000. Staff request Council approval to proceed with the study. Dependant upon the results of the study, staff would report back to Council with a request to proceed this year, or budget for the project in 1997. Staff request funding for this study from the Water Contingency Account 700-4123-910, transferred to the Professional Services account 700-4123-303.
