There are about 2,000 sewer accounts and 1,000 water accounts in Orono. A logical cost split could be to split the main control unit, and repeater costs 2/3 to 1/3 between the sewer and water funds respectively. The remote units at the plants and lift stations could then be charged to the appropriate funds. Below is a list of the estimated costs for budgeting purposes Cost of Main Control Unit at Public Works Building S90.000 F«timatgd Cost Repeaters at Two Water Towers $40J These costs would be split 2/3 sewer fund and 1/3 water fund Fstimated Cost for Remote Units is S8.000 per Site The Sewer Fund cost to monitor all 45 lift stations at an estimated cost of $8,000 per unit would be $360,000. The long term goal should be to eventually monitor all of the lift stations. This would virtually eliminate our dependence on neighborhood residents and the police to report alarms and notify public works. We have selected the top ten lift stations based on size and potential for property damage in the event of a malfunction. The proposed project plan is to budget for the installation of the main control unit and repeaters in 2002, remote units for the water plants, and installation of some of the lift station remote units. In subsequent years money should be budgeted for the installation of more lift station remote units based on a priority ranking of the lift stations.
