Chemical Storage Level Monitoring (19165)— Objective: Increase ease of access and availability of <br />information from existing devices and enhance reporting. <br />a. Chlorine Tank Level — Chlorine is stored as a compressed liquid in two active cylinders at each <br />location. Each cylinder is located on a weigh scale with one local display. <br />i. Provide integration with existing weigh scale transmitter including wiring to main <br />controller at each water treatment plant. Cylinder weights will be displayed in SCADA <br />screens as NET Chlorine in pounds. Levels will be historically logged and trended. Low <br />Alarm set point will be available to be configured by user to generate system alarm and <br />email notification. <br />b. Fluoride Tank Level — Hydrofluorosilicic acid is stored in a bulk container that is located on a <br />weigh scale inside an isolated room at each water plant. The level is displayed locally. <br />i. Provide integration with existing weigh scale transmitter including wiring to main <br />controller at each water treatment plant. Tank weight will be displayed in SCADA <br />screens as NET Fluoride in gallons (estimated by weight) with historical recording <br />available. Low Alarm set point will be available to be configured by user to generate <br />system alarm and email notification. <br />c. Corrosion Inhibitor Tank Level — Zinc Orthophosphate (LPC -9) is stored in a bulk container that is <br />located on a weigh scale inside each water plant. The level is displayed locally. <br />i. Provide integration with existing weigh scale transmitter including wiring to main <br />controller at each water treatment plant. Tank weight will be displayed in SCADA <br />screens as NET LPC -9 in gallons (estimated by weight) with historical recording available. <br />Low Alarm set point will be available to be configured by user to generate system alarm <br />and email notification. <br />d. Iron Treatment Tank Level — Potassium Permanganate is stored in a bulk container that is <br />located on a weigh scale inside the south (Navarre) water plant. The level is displayed locally. <br />i. Provide integration with existing weigh scale transmitter including wiring to main <br />controller at the south water treatment plant. Tank weight will be displayed in SCADA <br />screens as NET KMN04 in gallons (estimated by weight) with historical recording <br />available. Low Alarm set point will be available to be configured by user to generate <br />system alarm and email notification. <br />6. Softener Regeneration Operation and Reporting (2300)— Objective: Improve operation and create <br />automated report generation. <br />a. Provide controller programing to modify existing softener regeneration such that regeneration <br />starts at an operator time set point. In the event that more than one softener regeneration be <br />required per day the regeneration cycles will start sequentially with operator set delay time. <br />b. Provide monthly report that includes the number of regeneration cycles and calculated gallons <br />for each softener and the gravity filter. Report to include daily and month values for reporting <br />to MCES. <br />c. Provide annual report for totalized values for MCES requirements. <br />7. Alarm Dialer Improvements (1000)— The existing hardware alarm dialer at the South plant requires <br />modification to work with newer remote notification system used by city staff. Provide required <br />programming modifications to the hardware dialer and modifications to the plant controller to <br />coordinate the alarm functions. <br />IU SAL QN18030901-02 Orono Water System Improve ments.docx Page 3 of 5 <br />
