Utilities Supervisor Nelson stated there is a UPS (Uninterruptable Power Supply) at every <br />facility location, providing enough power during an outage to initiate an alarm and continue to <br />monitor the site. <br />Public Works Superintendent Riemer asked whether there is an alarm in case of UPS failure. <br />Utilities Supervisor Nelson confirmed this, adding UPS failure contributed to the City of <br />Blaine's recent water outages. <br />Utilities Supervisor Nelson stated there are eleven Public Works staff — four Utilities employees <br />and seven on -call employees — with SCADA password access, and all activity is recorded for <br />security purposes. He added the SCADA system controller is an easily accessed online <br />application. Utilities Supervisor Nelson stated the system is securely stored on a computer in the <br />Public Works Depaitinent. He added the City's SCADA System integrator, who lives in <br />Ramsey, has a duplicate software back-up. <br />Councilmember Kuzma asked how old the computer system is that is running the SCADA <br />software. <br />Utilities Supervisor Nelson stated it is approximately five years old. <br />Councilmember Kuzma requested that City staff review the possibility of upgrading the <br />computer system. <br />Councilmember Johns asked whether the SCADA system provides an "at a glance" option for <br />viewing all facilities, rather than viewing them one at a time. <br />Utilities Supervisor Nelson stated current data is located on each individual page and must be <br />viewed separately, but any alarm messages will be visible on the bottom of the screen. <br />Councilmember Kuzma asked whether the City has a reciprocal water agreement with the City of <br />Anoka. <br />Utilities Supervisor Nelson confirmed this, adding the reciprocal water connection, located near <br />Anoka Technical College, is currently being upgraded. Utilities Supervisor Nelson stated access <br />to well station cabinets and lift stations is continuously monitored. <br />Councilmember Kuzma requested that City staff compile a review of SCADA system function <br />redundancy for discussion at the Committee's next meeting. <br />Utilities Supervisor Nelson agreed. <br />Public Works Committee / March 21, 2017 <br />Page 4 of 9 <br />
