Title: Consideration and possible approval to purchase four (4) nitrification drives for the Truckee Meadows Water Reclamation Facility (TMWRF)in the amount of $187,600 from Intec Solutions.
Petitioner/Presenter: Neil C. Krutz, P.E. – Deputy City Manager/David Bruketta – Plant Manager/Kim Laber – Maintenance Manager
Recommendation: Staff recommends City Council approval to purchase two (2) nitrification effluent pump drives and two (2) nitrification influent pump drives from Intec Solutions.
Financial Impact: There is no General Fund impact. Funding to replace these remaining drives will come from reserved appropriations in Fund 5605. This expense will be charged to Account 604070, Capital Equipment and Furnishings, under Program 131510, TMWRF Maintenance. Following quarterly reconciliation of TMWRF operating expenses between the Cities of Sparks and Reno, affecting the Sanitary Sewer Operations Fund (1630), Sparks expects a reimbursement of up to $128,749.88 from the City of Reno based on the current ownership of TMWRF (31.37% for Sparks / 68.63% for Reno).

Agenda Item Brief: City staff is asking the City Council to approve the purchase of four (4) pump drives for the Truckee Meadows Water Reclamation Facility from Intec Solutions. The replacement of these drives will complete the Nitrification Drive Upgrade Project.
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 already failed and been replaced with the newer style ABB drive. Three additional drives are currently being replaced in this year’s TMWRF Capital CIP. The replacement of these last four (4) drives will complete the replacement of all eight (8) drives in the nitrification facility. TMWRF believes that the replacement of all the drives in the nitrification facility with units like those that are utilized in the Headworks facility is the direction staff would like to pursue. These new drives have modular components that will 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.
Analysis: Staff has determined that all of the original drives need to be replaced due to the unreliability of the equipment. One drive has completely failed and the other drives have incurred an unacceptable volume of intermittent failures which potentially puts the TMWRF discharge permit in jeopardy. The replacement of the remaining four (4) drives with the newer ABB modular designed drives will significantly increase the reliability of the nitrification facility in order to meet TMWRF’s discharge permit requirements. Total cost of project Reno share Sparks share $187,600.00 $128,749.88 $58,850.12 Percentages 68.63% 31.37%
Alternatives: Council could direct staff to provide other alternatives.
Recommended Motion: I move to approve the purchase from Intec Solutions in the amount of $187,600 with the City of Sparks share being $58,850.12.
