Consultant will help define spare parts inventory needed to improve wellfield <br />reliability. - <br />CONSULTANT will develop a table which outlines the specific requirements and <br />information on each of the wells, wellpumps, and motors. <br />CONSULTANT will evaluate standby generator capability and potential limitations <br />of existing standby power capacity. <br />CONSULTANT will evaluate the applicability of variable frequency drives (VFD's) <br />at the wells which may warrant installation of VFD's. The evaluation will consider <br />return on investment (ROI) and the additional maintenance and replacement costs <br />which can be inherent with VFD installation at wells. <br />Consultant will review existing raw water quality data with respect to the design <br />water quality used for membrane selection. Consultant will provide <br />recommendation of impacts to treatment plant or if further and additional raw <br />water quality analysis is necessary. <br />TASK 3 - SCADA SYSTEM and FIBER SYSTEM EVALUATION - WELLS <br />It is recommended to continue with the PLC upgrade project described in the Final <br />Report - Water Plant SCADA Improvements Evaluation, May 2015, and work <br />completed in early 2016 (Refer to -attached report schedule). The existing PLC and <br />control system is antiquated, has been discontinued, replacements are difficult and <br />costly to acquire, and Allen-Bradley has discontinued manufacturing and support <br />of the PLC5 hardware, which comprises the majority of the hardware at both water <br />plants. The completed system would provide all of the advantages noted <br />previously and also allow for any future changes to well sequencing. This will also <br />allow further well upgrades without installing additional CPU's at additional cost <br />at each of the wells. <br />Consultant will review fiber optic (FO) system, and identify final improvements to <br />complete the FO system to all wells at both water treatment plants. Consultant will <br />review previous construction documents and record drawings, provide field <br />investigations of each wellsite, and verify existing equipment at each well. <br />Consultant will review and identify individual well improvements to integrate FO <br />at each well and develop a summary of improvements that can be designed for <br />212 <br />FAUtilitieAUTILITY - Engineering\WATER\Wells\Admin\IRCU Floridan Well Improvements 1.29.18.docx Page 3 of 7 <br />
