Brown, County Administrator <br />Vincent Burke, P.E., Director of Utility Services <br />Arjuna Weragoda, PE, Capital Projects Manager <br />Work Order No. 15 with Kimley-Horn and Associates for the Control System <br />Implementation for Well No. 4 and 7 at South County RO Plant (SCRO) <br />DESCRIPTIONS AND CONDITIONS: <br />Indian River County Department of Utility Services (IRCDUS) owns and operates six (6) Floridan supply wells <br />that are the raw water supply and source water for the SCRO water treatment facility located on Oslo Road. <br />These wells are the lifeblood of the treatment facilities, and maintaining efficient operation of these well fields <br />is critical to the sustainability of the water system. <br />On July 12, 2016, the Indian River County Board of County Commissioners (BCC) approved the award of bid to <br />All Webbs Enterprises, Inc. for the rehabilitation of wells S3, S4, S5, and S6 to restore capacity and reliability of <br />the raw water supply wells to the water treatment plant and to construct a new well 57. During the initial <br />phases of rehabilitation of well S4, it became apparent that the existing PVC casing was damaged significantly <br />from previous work to the extent of not being salvageable. Therefore, on April 4, 2017, the BCC approved <br />Change Order No. 1 to All Webb's contract to include the construction of a new well S -4R in the same vicinity <br />as the old. Currently, completion of well S7 is scheduled for the end of October 2017. Each of the new well <br />designs include variable frequency drives (VFD) and fiber optic (FO) communication, which is a more robust <br />and reliable system over the existing radio telemetry (RTU) systems currently in place at all of the existing <br />wells. With the FO design, additional programming is necessary at both the water plant and well sites to <br />provide direct communication with the water plant Programmable Logic Control (PLC). Integration of control <br />and monitoring of these wells with the other wells is the last element needed to provide full operation of these <br />two wells. Once complete, two of the seven wells at SCRO will have direct, more reliable communication with <br />plant and wells S7 and S -4R. <br />ANALYSIS: <br />Staff requested that Kimley-Horn prepare a proposal for the integration and continuous monitoring of the two <br />new wells for flow, water level, pump speed and control of pump operation through the existing plant PLC via <br />Human Machine Interface (HMI) for the two new wells at the SCRO water treatment plant. The scope is more <br />specifically described in the attached Work Order No. 15. On November 4, 2014, the BCC approved the <br />Extension and Amendment of the Continuing Contract Agreement for Professional Services with Kimley-Horn <br />and Associates. The total negotiated cost for the control system implementation is outlined in Work Order No. <br />15 for a lump sum amount of $24,992.00. <br />C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@ 641D3B79\@BCL@641D3B79.docx <br />P243 <br />
