SUBMITTED BY: Max Linden, Wastewater Utility Engineer CONTACT PERSON/TELEPHONE: Max Linden, Wastewater Utility Engineer (509) 249-6814 SUMMARY EXPLANATION: Staff respectfully requests City Council consideration of a resolution declaring an emergency condition and waiving the formal bid process in order to purchase and install a VFD for the WWTP aeration blowers. The existing VFDs that serve the aeration blowers, which are vital components for the treatment process, are no longer supported by the manufacture. Numerous attempts to locate parts or repair services from other municipalities and industries, world wide, have not produced any successful results. The purchase and installation of this equipment not to exceed $70,000.

BOARD/COMMISSION RECOMMENDATION: COUNCIL ACTION: Resolution adopted. RESOLUTION NO. R-2005-146 Wastewater is in the process of updating the VFDs and blowers with new ones at this time. Unfortunately, the replacement of the VFDs and blowers will not occur for over one year and only three of the VFDs that run the four blowers are functional at this time. One VFD has been cannibalized to keep the other 3 running. Recently we have had some unanticipated break downs and one of the three remaining VFDs will now be needed to keep the other two running. If additional VFDs break down we would not be able to run the required number of blowers to maintain our activated sludge process in the aeration basins. This is especially critical when Del Monte is in full production and at other times when two blowers are required. Several effluent limits would be violated on the City of Yakima's NPDES discharge permit with out the required amount of air being delivered to the aeration basins. In addition, the safety and health of the citizens of Yakima could be jeopardized. We need to keep the remaining VFDs running for over a year until our new blowers have been installed. To get a replacement 400 hp VFD requires 6 to 8 weeks for delivery to the site and the size of VFD that is needed is not readily available. Robicon supplies the required VFD as well as having the parts and service readily available for them. Based on previous experience with Robicon we ordered the new VFD (PO # 05045) to get it shipped as soon as possible for installation in place of one of the old VFDs. The replaced VFD would then be used to supply parts to keep the other old VFDs running.
