Title
Resolution to Approve a Contract with Premier Pump, Inc., for Purchase of Six Effluent Pumps for the Wastewater Treatment Plant ($425,682.00)
Memorandum
Your approval is requested to award a Contract in the amount of $425,682.00 to Premier Pump, Inc., for the purchase of six vertical secondary effluent pumps for the City's Wastewater Treatment Plant (WWTP).
Funding for this project has been budgeted and is available in the approved Sanitary Sewer Fund Capital Budget.
The WWTP has six 150 horsepower secondary effluent pumps that are approximately 35 years old. Typically, two pumps are used to continuously pump secondary effluent into sand filters that comprise the plant's tertiary treatment process. Occasionally, when the Huron River is at high levels, additional pumps are used to pump secondary effluent simultaneously to the sand filters and the river.
Without sufficient secondary effluent pumping capacity, the WWTP would have to bypass tertiary treatment, risk discharging partially treated sewage into the Huron River or flood the treatment plant. Any such occurrence would be a violation of the WWTP's discharge permit and expose the City to potential fines of up to $25,000.00 per day per violation from the Michigan Department of Environmental Quality.
Over the past three years, three of the secondary effluent pumps have failed. One of the pumps was irreparable, and the other two pumps were repaired but are not reliable for long-term use. The remaining three pumps are fully functional but in a worn condition. Owing to the nature of the malfunctions and criticality of the pumps, Hubbell, Roth & Clark, Inc. (HRC) completed an engineering study to analyze the cause of the pump failure and assess the condition of the remaining pumps. The results of this study indicated the conditions of all the pumps were generally similar and their replacement was recommended.
Sttaff reviewed HRC's recommendations and concluded that due to their age an...
