The Truckee Meadows Water Reclamation Facility utilizes four raw sewage pumps to convey the incoming wastewater to the grit facility. These pumps were installed in 1992 and have performed beyond their useful life.  Because of the critical nature of these pumps and the inability to remove more than one from service at any given time, TMWRF Staff has implemented a serial repair program to rehabilitate one pump per year.  Raw Sewage Pump #4’s volute and base were replaced in late 2014. This purchase will address the replacement of one of the remaining pumps volute and base.

An inspection of the raw sewage pumps had determined that Raw Sewage Pump #4 needed to be addressed first and as a result was replaced prior to the start of the headworks rehabilitation project that is currently underway. Upon the completion of the headworks project a determination will be made as to which volute and base needs to be replaced next.  The parts being requested for the pumps, the volute and base, are most susceptible to wear and are common to all four pumps.   By rehabilitating and repairing the pumps the electrical and hydraulic efficiency of the equipment will improve.

Because the pump parts are proprietary they can only be purchased through the factory authorized representative, Nevada Seal and Pump. The quote cost includes the freight from the factory to TMWRF.

City Council could recommend that staff analyze alternative options.

I move to approve the purchase of replacement parts for a Raw Sewage Pump at the Truckee Meadows Water Reclamation Facility (TMWRF) from Nevada Seal and Pump in an amount not to exceed $148,517.
