Title: Consideration and possible ratification of a purchase from Intec Solutions in the amount of $36,900 to supply a 200 HP nitrification influent pump drive.

Petitioner/Presenter: Neil C. Krutz, P.E., Community Services Director/Kim Laber, Acting Maintenance Manager

Recommendation: Staff recommends City Council purchase from Intec Solutions a drive in an amount of $36,900

Financial Impact: $296,000 in appropriations is contained in the Fiscal Year 2011-2012 Truckee Meadows Water Reclamation Facility (TMWRF) operating budget for capital maintenance events. This expense will be charged to Account 604070, Capital Equipment & Furnishings under Program 131510, TMWRF Maintenance. Following quarterly reconciliations between the Cities of Sparks and Reno it is expected that the overall impact will be up to $11,575.53 for the City of Sparks and $25,324.47 for the City of Reno.

Total Costs: $36,900.00

Fund: Joint Treatment Plant Account: 604070
Program: TMWRF Maintenance (131510)
Amount: $36,900.00 Budget Status: Budget Exists

Business Impact (Per NRS 237):
A Business Impact Statement is not required because this is not a rule.

Agenda Item Brief: City staff is asking that City Council approve a purchase with Intec Solutions to replace a damaged 200 HP nitrification influent pump drive. This drive controls a 200 Hp motor that delivers secondary effluent to the six (6) towers at TMWRF. This pumping is part of maintaining compliance with TMWRF’s discharge permit.

Background: The nitrification complex at TMWRF houses four (4) 200 HP and four (4) 400 HP electrically driven pumps. The 200 HP pumps deliver secondary effluent to the six (6) towers which treat the ammonia that is present in the secondary effluent. The effluent from the towers is then returned to the nitrification facility and pumped using the 400 HP pumps to the denitrification reactors where the process releases nitrogen gas to the atmosphere. This process is essential to avoid releasing nitrogen compounds into the Truckee River in violation of our permit. Normal operation requires that two (2) 200 HP and two (2) 400HP operate at all times. One 200HP pump drive has failed leaving only (1) pump and drive for redundancy. In the event that another 200 HP drive or pump should fail TMWRF would be left without a redundant pump and drive which could potentially result in permit violations. TMWRF believes that the replacement of the drive with a unit like those that are utilized in the headworks facility is the direction staff would like to pursue. These new drives have modular components that would allow TMWRF electrical/instrumentation staff to make repairs from warehouse stock within hours of a component failure. Standardization of all the major drives at TMWRF would allow for reduced equipment down time and ease of equipment repairs in the event of a failure. Maintenance of permit related redundant equipment is paramount to TMWRF meeting its goals of protecting the public health, safety and welfare of the community. Intec Solutions is the sole dealer of the desired equipment due to restrictions in distribution from the manufacturer, effectively making the vendor the sole source for the needed equipment.

Analysis: Due to the mission-critical nature of this equipment, staff has already initiated the emergency purchase of the required equipment with the authorization of the City Manager. This staff report is written in order to ratify that action as the total cost is in excess of $25,000.00.

Alternatives: Council could direct staff to provide other alternatives.

Recommended Motion: I move to approve the purchase with Intec Solutions in the amount of $36,900 with the City of Sparks share being $11,575.53.
