Assistant City Engineer DATE: September 17, 2010 SUBJECT: APPROVAL OF AWARD AND AUTHORIZATION OF ISSUANCE OF A PURCHASE ORDER WITH APSCO, INC FOR TURBO BLOWERS FOR A NOT-TO-EXCEED AMOUNT OF $280,000.00 AND APPROVAL FOR THE PURCHASING MANAGER TO SIGN PURCHASE ORDER (Next Available Consent Agenda) I. RECOMMENDED ACTION A. Move to: Approval of award and authorization of issuance of a Purchase Order with APSCO, Inc. for Turbo Blowers for anot-to-exceed amount of $280,000.00; and 2. Authorize the Mayor to sign the agreement II. DEPARTMENT CONTACT PERSONS Clint Dolsby, Asst. City Engineer (Project Manager) 489-0341 Warren Stewart, PW Engineering Manager 489-0350 Tom Barry, Director of Public Works 489-0372 III. DESCRIPTION A. Background The Public Works and Planning Departments have acquired grant funding of a combined $287,000 from the Department of Energy and Idaho Power for energy Page 1 of 3 efficiency improvements at the Wastewater Treatment Plant. These grants plus an the budget amendment that was approved at the April 27, 2010 Council meeting and the budget for this project that was approved for fiscal year 2011 will fund the design and construction of the turbo blowers and energy efficiency improvements that are estimated to save more than $4,000 a month in energy costs. B. Proposed Project Air for the aeration basins at the Wastewater Treatment Plant is currently provided by three multi-stage blowers located in the blower building. The replacement of the multi-stage aeration basin blowers with high efficiency turbo blowers and aeration system efficiency improvements has the potential to save several thousand dollars per month. The procurement of the turbo blowers is the first step towards the completion of this project. Following this equipment procurement, the City plans to install the turbo blowers and implement the aeration basin efficiency improvements in fiscal year 2011. C. Contractor Selection APSCO, Inc. was the lowest bidder and is qualified to provide the specified equipment package. N. IMPACT A. Strategic Impact: This project supports the Public Works Mission and Vision for emphasizing financial stewardship and environmental sustainability. The proposed improvements are responsive, innovative, and increase operational efficiencies while saving the City several thousand dollars a month in energy. B. Service/Delivery Impact: The improvements will reduce the power consumption of the Wastewater Treatment Plant through the installation of more efficient blowers and aeration efficiency improvements. C. Fiscal Impact: Project Costs Base Bid Amount Total Cost Project Funding $280,000.00 $280,000.00 Meridian WWTP Blower Replacement (3590-96101) $280,000.00 Page 2 of 3 Total Funding $280,000.00 Construction Grant Funding Idaho Power Grant $112,000.00 Department of Energy Grant $175,000.00 Total Grant Funding $287,000.00 V. ALTERNATIVES A. The City could defer the turbo blowers and aeration basin air efficiency improvements. However, the Department of Energy Grant must be spent within a year and a half from acquisition, Public Works may run into time constraints to complete this project if it is deferred. This would also delay realization of the energy savings and operational improvements. VI. TIME CONSTRAINTS Council's approval will allow for the acquisition of the blowers in early FY11. VII.

HIGH SPEED TURBO BLOWER ASSEMBLY 1) Shaft /Air Bearing Main shaft is directly connected with impeller and hydrodynamic air foil bearings construct oil-less lubrication system. Lifting force produced by pressure gradient around the rotating shaft makes no mechanical contact between shaft and journal. This fact makes various complicated components unnecessary such as oil bearing, seal, oil filter, cooler, etc., which are used for the existing high speed turbo machine. 2) Variable Frequency Driver (VFD) The combination with the frequency modulation of inverter and PM motor controls the speed of impeller, flow rate and/or discharge pressure. 3) PM motor PM (permanent magnet) motor rotates by the electromagnetic interactions between stator oohs and the rotor made of permanent magnets. It can start under 10 % of rated current, and operate with high speed and high effiaency of 9.~r-97%. (1) PM (Permanent magnet) motor (460 Volts, 3 Phase, 60 Hz, fan cooled) (2) Start: under 10% of current at design condition. (3) Insulation: Epoxy coated Class H. (4) Maximum Ambient temperature: above 120 Deg F (5} Stator Temperature Detector: Two thermal protectors in the stator windings {one each end). Rod and tube type or similar that is sensitive to rate of rise as well as temperature. (6) Bearing: Air foil bearings. (7) Electric Standards: IEEE, ANSI, and NEMA. (8) Frequency sensing: sensorless. 4) Blower Local Control Pane! LCD Display shows some measurement dam and alarm signs as follows; -Air temperature of Intake and discharge - Differential pressure at intake fitter - Discharge pressure ... ~ S -Flow rate of air - Rotating speed -Current /Power - Error code -Accumulated running hours 5) Sensors - Sensors for the measurement of intake/discharge air temperature - Sensor for the measurement of discharge pressure - Sensor for the measurement of intake differential pressure - DC current sensor - Overheat sensor at inverter -There are motor temperaiure switches instead of sensors 6) 17-4PH Stainless Steel Cast Impeller 7) DC choke inside a package 8) I(Turbo blower designed to minimize the footprint required for installation.
