Title: Consideration and possible approval of a purchase from Pacific Water Resources in the amount of $243,226.00 for one Nitrification Influent and one Nitrification Effluent pump for the Truckee Meadows Water Reclamation Facility.

Petitioner/Presenter: Neil C. Krutz – Deputy City Manager./Michael Drinkwater, P.E. – Plant Manager / Kim Laber – Maintenance Manager.

Recommendation: Staff recommends City Council approve the contract between the City of Sparks and Pacific Water Resources in the amount of $243,226.00 for redundant nitrification influent and effluent pumps

Financial Impact: There is no impact to the General Fund. There remains $803,373.48 in appropriations for this capital acquisition, contained on the Internal Project list for Fiscal Year 2015-2016. Expenses will be charged to TMWRF, Fund 5605, Account 604070, Capital Equipment and Furnishings using Program 131505, TMWRF Operations. Following quarterly reconciliation of TMWRF’s operating expenses between the Cities of Sparks and Reno, affecting the Sanitary Sewer Capital Project Fund (1631), Sparks expects a reimbursement from the City of Reno based on the current ownership of TMWRF as outlined in Attachment 1 and supported in the inter-local agreement for the operations of the facility.

Total Costs: $243,226.00

Fund: Joint Treatment Plant Account: 604070
Program: TMWRF Operations (131505)
Amount: $243,226.00 Budget Status: Budget Exists

Agenda Item Brief:

City staff is asking the City Council to approve a purchase from Pacific Water Resources in the amount of $243,226.00 for a redundant nitrification influent and effluent pump for the Truckee Meadows Water Reclamation Facility.

Background:

The Truckee Meadows Water Reclamation Facility (TMWRF) uses nitrification influent pumps to pump secondary effluent to six nitrification towers as part of the nitrogen removal process that is part of our Nevada Department Environmental Protection (NDEP) discharge permit. The plant has four influent pumps total with three pumps running leaving one pump as a redundant pump. The discharge water from the towers is pumped to the Denitrification facility with the nitrification effluent pumps. The plant also has four effluent pumps total with three pumps running leaving one pump for redundancy.

In the past the plant only used two influent and two effluent pumps to process the secondary effluent. This would allow a pump to be removed from service and still leave a redundant pump. Due to increasing pressure to reduce the annual average nitrogen discharge load the process now requires that the plant run three influent and effluent pumps which does not leave a redundant pump when a pump is removed for service. Turnaround time for pump rebuilding is four to six weeks.

Staff would like to have a spare influent and effluent pump in stock to put in immediate service when either an influent or effluent pump is removed for service. The influent and effluent pumps are also not interchangeable.

Analysis:

The nitrification influent and effluent pumps require periodic maintenance for impellor and bearing wear. Staff has determined that in order to service these units and maintain redundancy for a critical process that spare unit needs to be purchased.

Because the pumps are proprietary they can only be purchased through the factory authorized representative, Pacific Water Resources. The quoted cost includes freight from the factory to TMWRF.

Alternatives:

Council could direct staff to provide other alternatives.

Recommended Motion:

I move to approve the purchase from Pacific Water Resources in the amount of $243,226.00 for one nitrification influent and one effluent pump.
