Coi ^^cpTING JUN 2 8 2004 CITY OF ORONO REQUEST FOR COUNCIL ACTION DATE: June 28,2004 ITEM NO.// Department Approval: Name Grcgor>'A (iappa Title Director of Public Services Admini.<ttrator Reviewed: Agenda Section: Public Services Director's Report Item Description: Purchase Backup Dialenlbr the Sewer SCADA System We recently c.xpcrienced a sewer backup into the basement of a home on Baysidc Road w hich w as caused by failure of the West Luke Street lifi station. This lift station is one of the ten .stations that have the SC!ADA automated alarm system installed, fhe SC'ADA system did register the lift station malfunction and successfully sent an alarm signal to the public works garage. However, the dialer system software did not work properly, and the public works on call person was not notified of the alarm. We have been experiencing a sporadically reoccurring problem with the dialer system. The vendor is having a difficult time finding the problem because when he comes to fix the problem everything works successfully. We are continuing to work on solving this problem, but are concerned about the total reliability of the dialer system. The existing Navarre water plant control system has an alarm and dialer system, which has been functioning fine since 1 999, to notify the public works on call person of problems at the water plant. This w ater plant system could be expanded to function as a backup dialer system in the event of a failure of the SCADA .system. The SCADA system provides detailed alamis on lift station problems while the water plant backup system would only provide a general alarm notification of a problem at a particular lift station. Our recommendation is to purehasc a backup alarm dialer system for the SCADA system from Automatic Control Systems for a cost of $7,798. W'e will also continue to work on solving the problem with the SCADA system dialer. This backup dialer will provide an additional level of protection in order to further reduce the potential for sewer backups, fhe cleanup and restoration costs for one sewer backup could easily exceed the costs of the dialer system. In addition, it would prevent the homciiwner inconvenience and difficulties caused by sewer backups. COUNCIL ACTION REQUESTED: Motion to approve the purcha.se of a backup dialer for the SCADA system from Automatic Systems Company. Roseville, Minne.sota. in the amount $7,798, to be funded from the 2004 Sewer Lund Budget, w ith approval of a budget ad justment to reflect this expenditure.
