CITY OF COLTON Item #18 AGENDA REPORT FOR THE COLTON UTILITY AUTHORITY MEETING OF FEBRUARY 17, 2004 TO: HONORABLE CHAIRPERSON AND UTILITY AUTHORITY MEMBERS FROM: ERIC R. FRASER, DIRECTOR OF WATER & WASTEWATER OPERATIONS SUBJECT: APPROVAL OF A CONTRACT FOR THE REPAIR OF BLOWER ENGINE NO. 3. DATE: February 9, 2004 BACKGROUND The Colton Water Reclamation Facility (CWRF) utilizes methane/natural gas burning engines that drive blowers to supply air for the biological treatment process. There are currently two gas -driven engines available for this purpose as well as one electric motor driven blower. Due to the high cost to operate the electric blower (—$650/day), it is only used in emergency situations. The engine that drives Blower No. 3 failed and needs immediate repairs to ensure process reliability. DISCUSSION/ANALYSIS The treatment process at the water reclamation plant generates methane gas that is used as a fuel source for two engines that drive blowers. Natural gas can also be purchased to operate these engines. The air produced by these blowers is utilized in the biological process and is necessary 24 -hours per day/seven days per week. Under current conditions, one gas -driven blower is needed to provide air for the biological process. Normally, one engine is operating to meet these air requirements and the other is ready to put into operation when the operating blower needs to be shut down for maintenance or as needed by the treatment process. In June 2003, maintenance staff determined that Blower Engine No. 3 needed to be rebuilt due to low compression on six of the eight cylinders. The engine was taken out of service to prevent further damage. Bids to remove, overhaul and install the engine are scheduled to be opened at 10:00 A.M. on February 12, 2004. A supplemental staff report recommending award of bid will be issued after the bids are analyzed. FINANCIAL IMPACT It is anticipated that the engine overhaul will cost approximately $65,000. Funds are available in the Wastewater Fund, under Operations Equipment Account No. 522-8200-8200-4955-0000. ENVIRONMENTAL IMPACT There is no environmental impact. CONFLICT OF INTEREST Exact Business Name: (To be included in the supplemental staff report on February 17, 2004.)
