CHANDLER <br />COUNTY ADMINISTRATOR <br />FROM: TERRANCE G. PINTO <br />DIRECTOR OF UT1140 SSXR21VICES <br />PREPARED WILLIAM F. M CA , P.E. <br />AND STAFFED CAPITAL PR S ENGINEER <br />BY: DEPARTMEUTILITY SERVICES <br />SUBJECT: 900 MHZ COMMUNICATION SYSTEM <br />RETROFIT/CONVERSION OF EXISTING PUMP STATION <br />SCADA SYSTEM <br />BACKGROUND <br />As part of the total implementation of our 900 MHZ Communication <br />System, we are changing our radio communication system for pumping <br />stations (SCADA) to a 900 MHZ supplier. With the implementation of <br />a utility wide 900 MHZ system, communication will become not only <br />uniform but it will provide a more competitive way of purchasing <br />the Radio Telemetry Units (RTU) for the pumping stations as they <br />will not be proprietary as with the existing system. <br />ANALYSIS <br />The Utilities Department has budgeted for the conversion and <br />implementation of the aforementioned new SCADA communication <br />system. As indicated, the new 900 MHZ will provide expanded <br />functions at a cost savings of approximately $900.00 per unit, when <br />compared to the existing 406 MHZ system. The change will also <br />provide compatibility to the operating control system for each <br />wastewater treatment plant. <br />RECOMMENDATION <br />The staff of the Department of Utility Services recommends that the <br />Board of County Commissioners approve the commencement of the 900 <br />MHZ System implementation and conversion as outlined above changing <br />from the Data Flow System to the consolidated Data Flow Scada <br />System. <br />97 <br />November 5, 1996 BOOK 99 FACE 614 <br />
