1 <br />Materials and Services Proposed <br />In Control, Inc. <br />10350 Jamestown Street NE <br />Blaine, MN 55449 <br />Phone: (763) 783-9500 <br />1. Well 4 Integration (9921)— Objective: Provide duplex well functionality for the north water plant <br />with alternator sequencing. <br />a. Well 3 and Well 4 pumps to be controlled by AFDs with manually set speeds at the local device. <br />Provide alternator sequence control at the local PLC and monitor pump run status, real time <br />pump flow rates and associated alarms. Alternator to be optionally controlled through SCADA <br />system. Well control to reference pressure level of north elevated storage tank. <br />b. Programming of local controller and local operator interface and modifications to SCADA system <br />to allow remote management and monitoring will be completed. Flow to be historically logged. <br />c. Create reporting function at SCADA computer. Report to be monthly layout in Excel with daily <br />totals and min/max daily values. <br />d. Written functional description will be provided. <br />Chemical Feed Pacing (18070) — Objective: Increase accuracy of chemical treatment <br />a. Provide integration of existing chemical feed pumps to controllers at each water treatment <br />plant. Chemical pacing to be controlled from the existing flow transducers. <br />i. Compete installation and termination of wiring where required to provide control <br />signals to existing chemical pumps. Furnish new controller modules as required. Provide <br />new control screens for each chemical pump to allow operator adjustable set points. <br />Set points to be historically logged. <br />Variable control of the following pumps: <br />1. North Plant: <br />a. (1) Chlorine <br />b. (2) Fluoride <br />c. (1) Corrosion Inhibitor <br />2. South Plant: <br />a. (1) Chlorine <br />b. (2) Fluoride <br />c. (1) Corrosion Inhibitor <br />d. (1) Iron Treatment <br />3. Well Drawdown Monitoring (9129) — Objective: Provide monitoring and reporting <br />a. Complete wiring for (2) existing well drawdown measurement devices to local controller at <br />North plant <br />b. Complete wiring for (2) existing well drawdown measurement devices to local controller at <br />South plant <br />c. Integrate drawdown measurements in SCADA display with low level set point alarm. Alarm to <br />be permissive for well to operate. Drawdown levels to be historically logged <br />d. Create drawdown report to meet requirements of MNDNR in Excel format. <br />e. Provide historical trending function in SCADA to review drawdown in comparison to pump run <br />status and flow rate. <br />4. North Water Tower Low Temperature (500)— Objective: Provide monitoring <br />a. Furnish one temperature sensor. Integrate with SCADA to provide alarm notification. <br />IU SAL QN18030901-02 Orono Water System Improvements.docx Page 2 of 5 <br />
