Item No: 07J Meeting Date: June 13, 2016 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Don Peterson, Public Works Supervisor Item Title/Subject: Resolution 8598, Approving the Upgrade for the SCADA (Supervisory, Control, and Data Acquisition) Computer Program. Background/Discussion: The City of Mounds View has operated a water and sewer distribution system since the early 1960s. These are critical health and safety services vital to our everyday lives for these systems need to operate 24 hours a day, 365 days a year. Both the water and sewer systems have pumping equipment require operation without failure. The water pumps ensure that the City has an adequate water supply for public use and for fire protection. The sewer pumps ensure that there are no health risks or property damage due to sewer back-ups. The SCADA (Supervisory, Control, and Data Acquisition) is a computer system for operating the City's utility systems. It was originally installed in 1989, and upgraded in 1998, and 2007. This system consists of a computer, hardware, software, and communication devices to control the functions of the City’s water and sanitary sewer infrastructure systems. SCADA monitors and controls the City’s water storage capacity, treatment plant operations, all wells and boosters pumps, and sanitary sewer lift stations. This system allows staff to monitor operations and to be notified immediately of any monitored failure. Staff can also review pumping flows and tank elevations to optimize efficiency and reduce power demand to save on energy bills and participate in energy load management programs. In 2012, while preventive maintenance was being performed on the water tower, the water plant operations had failures and the system did not report/call out to Staff. Automatic Systems Company was called to diagnose the problem and found multiple alarms turned off in the initial set up of the SCADA program by the past vendor. Staff along with Automatic Systems, started looking into the system further in order to find if there were additional issues; the system was diagnosed and repaired. The largest issue with the SCADA system is the age of the computer and the software program, both of which are past the life expectancy. While this is no longer a proprietary software program, Automatic Systems Company has been the sole contractor the City has been using for a number of previous projects such as replacing the VFDs in the booster station, analyzing software alarm issues, repairing the outdated software program, the Groveland lift station including controls, and improvements in the software reporting alarms and functions for the lift station.
