REQUEST FOR COUNCIL ACTION <br />DATE: December 12, 2016 <br />ITEM NO: 11 <br />Department Approval: Administrator Reviewed: Agenda Section: <br />Name Adam Edwards Y"-/- Public Works Director/ <br />Title Public Works Director/City Engineer City Engineer's Report <br />Item Description: Supervisory Control and Data Acquisition (SCADA) Upgrade <br />List of Exhibits <br />A. Bolton & Menk SCADA Report. <br />1. Purpose. The purpose of this action item is to gain Council approval for the SCADA upgrade <br />proposal. <br />2. Background. The City of Orono operates water and wastewater utilities that serve the City residents <br />with vital services. To monitor and control these systems the City relies on a couple SCADA systems: <br />Rockwell Automation FT View for the water system and 3 Sanitary Lift Stations and Mission Alarms for <br />9 Lift Stations. The City currently has a SCADA system that was constructed as part of projects in 1998 <br />and 2002. In the last few years, the City has started a multi-year program of upgrading lift stations. When <br />a station is upgraded, it receives a new lift station control panel with "Mission" cellular alarm monitoring <br />system. The Mission alarm monitoring has been effective and reliable in alerting the City to lift station <br />problems. The water SCADA system has become cumbersome due to changes in computer operating <br />systems. The software that was developed for the original project is difficult for the operators to use, and <br />does not include many of the enhancements that are available from current products. The older computer <br />software is no longer supportable, and can only stay in service as long as the City continues to run the <br />Windows XP operating system that resides on the SCADA computer. In December 2015 the Council <br />authorized Bolton and Menk to conduct a study of the system and make recommendation for upgrades. <br />3. Scope of Work. Based on the study and staff experience, staff developed 5 SCADA upgrade projects: <br />Utility <br />Project <br />Description <br />Water <br />1 <br />Upgrade SCADA <br />Replace two computers new desktop PCs with new <br />Computers and Software <br />SCADA software.
