<br />Item No. 7H <br />Meeting Date: May 29, 2007 <br />Type of Business: CB <br />WK: Work Session; PH: Public Hearing; <br />CA: Consent Agenda; CB: Council Business <br />City Administrator Review _______ <br /> <br />City of Mounds View Staff Report <br />To: Honorable Mayor and City Council <br /> From: Mike Schnur, Lead Utility Worker <br /> <br />Item Title/Subject: Resolution 6895 Approving a Contracts for the SCADA <br />(Supervisory, Control, and Data Acquisition) System <br />Upgrade No. 2 <br /> <br />Background: <br />The City of Mounds View has operated a water and sewer distribution system since the <br />early 1960’s. These are critical health and safety services vital to our everyday lives <br />that need to operate 24 hours a day, 365 days a year. Both the water and sewer <br />systems have pumping equipment that needs to operate without failure. The water <br />pumps ensure that the City has an adequate water supply for use and fire protections. <br />The sewer pumps ensure that there are no health risks or property damage due to <br />sewer back-ups. <br /> <br />These systems are monitored by the City’s SCADA (Supervisory Control and DATA <br />Acquisition) system. <br /> <br />The SCADA system was originally installed in 1989, and upgraded in 1998. This <br />system consists of computer hardware, software, and communication devices to control <br />the functions of the City’s water and sanitary sewer infrastructure systems. The SCADA <br />System monitors and controls the City’s water storage capacity, treatment plant <br />operations, all wells and boosters pumps, and sanitary sewer lift stations. <br /> <br />This system allows staff to monitor operations and be notified immediately of any <br />monitored failure. The City can also review pumping flows and tank elevations to <br />optimize efficiency and reduce power demand to save on energy bills and participate in <br />energy load management programs. <br /> <br />There are a total of ten sites where communication is needed to operate the system. <br />Five sites are external sites, located away from the City Hall and Public Works building <br />facilities area and five are internal sites located within this area. The current way for the <br />SCADA system to communicate back and forth from the five external, and five internal <br />sites, is by dedicated communication (telephone) lines. The five internal sites use City <br />owned and maintained communication lines, while Qwest provides the five external <br />communication lines. These dedicated Quest communication lines currently cost the
