Title
Approving the procurement of a vertical turbine motor in the amount of $86,805, and authorizing the City Manager to execute the same.
Summary
The Surface Water Treatment Plant currently utilizes 4-600 HP vertical turbine motors that are responsible for pumping water into the City’s water distribution system through the City’s High Service Pump Station. These pumps are absolutely critical in ensuring that the City can continue to meet system demands during peak day and peak hour situations during the summer. As part of the FY2024 budget, City staff allocated a portion of the Maintenance and Repairs line item in the operations budget to perform an evaluation and complete needed repairs as needed on the pump and motor for one of the High Service Pumps. When the motor for one of the High Service Pumps was pulled and evaluated, it was determined that the rotor was damaged which would cause a high vibration in the motor and pump which would eventually cause long-term damage to the pump causing premature failure. Due to the size of the motor and the nature of the damage, the rotor itself cannot be repaired and would need to be replaced in-kind.
Staff requested a proposal to replace just the rotor and also requested for a proposal for a new motor. The repair proposal was roughly 75% of the cost of a new motor and given that the motor windings are of an unknown status after being in service for over 17 years, the cost to repair the motor could easily become more expensive than replacing the motor entirely with a new unit. While operations staff would like to have the motor replaced soon, the High Service Pump Station is designed with a “N+1” capacity which accounts for one of the units being out of service at all time so this pump and motor being down will not affect the system’s capacity to distribute water throughout the peak summer months if there are delays with the replacement.
This item will meet the City’s Strategic Plan goal of Infrastructure as...
