RE:                                          Proposed Amendment No. 3

                     Contract No.1067

                     Parts & Repair Service for Various Pumps and Grinders

                     Vendor:  Detroit Pump & Mfg. Co.



Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Interim Chief Executive Officer (ICEO) to enter into Contract No. 1067, Proposed Amendment No. 3, “Parts & Repair Service for Various Pumps and Grinders” with Detroit Pump & Mfg. Co., with an increase of $292,882.00 for a total cost not to exceed $1,100,000.00 and an increased duration of 199 days for a total duration of 2,027 days; and authorizes the ICEO to take such other action as may be necessary to accomplish the intent of this vote. 


The Wastewater Team operates and maintains many pumps to convey wastewater including dewatering tanks, provide flushing water, etc. The wastewater that these pumps convey contains abrasive materials like rocks, gravel, and many other solids that originate from the combined sewer systems that are upstream of the WRRF and CSO facilities. The solid-bearing wastewater that our pumps convey increases the frequency of wear and damage that our pumps experience.


Wastewater pump failures can occur at any time based on the amount of gravel and solids that enter a facility, especially during a storm event. GLWA uses contractors to assist with repairs including troubleshooting or rebuilds.  This amendment will provide for continuous pump repair services while GLWA works on procurement for a replacement contract. Regular repairs and rebuilds of our pumps are required for maintaining compliance.
