Absent: None. <br /> <br />COMMITTEE BUSINESS <br /> <br />Case #5.1 Overview of the Utility Department SCADA System <br /> <br />Utilities Supervisor Nelson reviewed the staff report. <br /> <br />Commissioner Elvig asked how thick the ice can get. <br /> <br />Utilities Supervisor Nelson said he has heard of the ice getting six feet thick, though that is in <br />extreme climates. He did not think the climate here is cold enough to create ice that thick. <br /> <br />Commissioner Elvig questioned whether there is a constant evolution of the water. <br /> <br />Utilities Supervisor Nelson explained there is a control that automates this, and demonstrated <br />how the water fluctuates. He indicated there are alerts built into the SCADA system and <br />discussed the events that would trigger an alarm. <br /> <br />Public Works Director Olson commented there is a manual check daily to be sure there are <br />ample chemicals in the tanks. If there is a chemical leak, the alarm will be set off. <br /> <br />Commissioner Elvig questioned what the security override is. <br /> <br />Utilities Supervisor Nelson responded the system is password protected, and the keys to the <br />pump house are kept by Staff. If this system fails, there is a backup system that will send a <br />notification if there was a computer crash. In addition, there is another computer as backup. <br /> <br />Public Works Director Olson and if an employee were to leave <br />the City, passwords would be changed. <br /> <br />Chairperson McGlone asked if this is tied into the wellhead protection. <br /> <br />Utilities Supervisor Nelson answered it is the reason for the wellhead protection. <br /> <br />Case #5.2 Overview of the 2011 Street Maintenance Program <br /> <br />City Engineer Himmer reviewed the staff report. <br /> <br />Chairperson McGlone noted there was a lot of curb damage last year, leaving less in the budget <br />to work with this year. He wanted to be sure the resources were not exceeded. He questioned <br />what funds would be used for pothole repair since MSA funds are depleting. <br /> <br />Public Works Director Olson explained that pothole repair would come from the General Fund. <br /> <br />Public Works Committee / February 15, 2011 <br />Page 2 of 7 <br /> <br />
