<br />Memo <br />SCADA SYSTEM <br />2 <br /> <br />l <br /> <br />In addition to improving our current monitoring system, the following two factors are driving <br />this process: <br /> <br />- <br /> <br />1. The unexpected and unbudgeted rate increase from our current monitoring vendor <br />and the telephone company which doubled our monthly rate. <br /> <br />2. The move ofthe O&M Department into the Ramsey County Maintenance Facility <br />in November of2004. <br /> <br />BUDGET <br />The Council adopted the 2004 CIP Budget which includes an allocation of $60,000 for the <br />purchase of a SCADA system for eight (8) Lift Stations. The remaining six (6) Lift Stations <br />would be fitted 'Yith a SCADA system at the time of their reconstruction. The Booster Station <br />and the two water towers were tentatively scheduled to receive a SCADA system in the 2006 <br />CIP Budget. Staff has determined that the one time cost to install a SCADA system for the <br />fourteen (14) Lift Stations, Booster Station, and the two (2) water towers would be $240,000. <br />Proposed funding sources would be the Water Enterprise Fund and the Sanitary Sewer Enterprise <br />Fund. The actual breakdown of funding would be as follows: <br /> <br />80% from Water Enterprise Fund or $192,000 <br />200/0 from Sanitary Sewer Fund or $48,000 <br /> <br />e <br /> <br />Currently, each of the above mentioned Enterprise Fnnds has a $1,000,000 balance. <br /> <br />Current annual expenses to monitor the fourteen (14) Lift Stations, Booster Station, and two (2) <br />water towers are as follows: <br /> <br />Monitoring System Contract & Telephone Service <br />Staff Time to visit each monitoring site during work week <br />Total Annual Cost: <br />*Based on 2004 current service rates and O&M Union salary structure. <br /> <br />$24,500.00 <br />11,200.00* <br />$35,700.00 <br /> <br />A SCADA system would pay for itself aflcr six and one-half (6.5) years based on 2004 Total <br />annual costs.
