Motnvns ViEw City of Mounds View Staff Report Item No: 9K Meeting Date: December 11, 2017 Type of Business: CB Administrator Review: illi To: Honorable Mayor and City Council From: Don Peterson, Public Works Director Item Title/Subject: Resolution 8866, 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 1960's. 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 that 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. 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. The SCADA system was originally installed in 1989, and the following actions have taken place: • Software system upgrade in 1998 • Software system upgrade in 2007 • Partial software upgrade in 2016 During these upgrades in 2016 it was highly recommended that an alarm backup dialer system be installed (this would be a land line phone dialer). Currently if the battery backup to the computer fails, no alarms would be sent out. Having a backup system would ensure that Staff would be notified of power loss and other alarms. With plans to build a new Public Works facility, the addition of a backup dialer was put on hold until the SCADA system can be moved to the new Public Works facility. (The SCADA system was relocated in 2017 to the main water treatment plant and was planned to be moved back into the new Public Works Facility in a location that all Public Works Staff is more frequently around.) Staff received a quote for relocating and updating the SCADA software program, from (AE2S) Advanced Engineering and Environmental Services Inc. for $38,975. Funding will be taken from account 700-4823-7030 (Water Fund), with a 2017 budget of $42,640 for SCADA system upgrades.
