9.9.2 Repair and Replacement Costs Repair and replacement costs, shown in Table 9.3, are divided based on ownership. Maintenance costs are likely to be lower for a joint utility compared to individual development since less infrastructure will need to be maintained and administrative costs can be combined. Table 9.3 Summary of annual repair and replacement costs for Options 1, 2, and 3 9.9.3 Anticipated Water Costs Anticipated water costs are shown in Table 9.4. The average cost of 1,000 gallons (kgal) of water sold in the six -city region in 2010 was $2.07. The cost of water is expected to increase in both Individual Development and Joint Development scenarios as more infrastructure is needed to accommodate growth and maintenance costs. However, the increase in costs is less for joint development as less infrastructure is required per person served. Table 9.4 Average cost of water per 1000 gallons sold Cost per thousand gallons 2010 (average) $207 2030 Joint Development $277 2030 Individual Development $295 9.2 Analysis of Options 1, 2 and 3 9.2.9 Comparison of Capital Costs Capital Costs for Option 1 —jointly owned supply, storage and treatment system The cost estimates for Option 1 were developed using population projections and historical water use data. Using this data, the trigger charts in Figures A5 and A7 were created. The trigger charts were used to estimate when additional wells and storage would be needed. Future watermain was adapted from cities' comprehensive plans and additional watermain was added to connect all of the cities and provide looping to improve circulation where it was needed. The joint system would need specific locations of trunk watermain installed to facilitate interconnections and combine the separate distribution systems. This cost is estimated to be the same or less than individual 2030 trunk watermain costs, but the future watermain would be in slightly different locations or slightly larger in Joint Water Utility Feasibility Study 30 Option Z Option 2 Option 3 Centerville $300.000 $0 $500.000 Circle Pines $300,000 $0 $500,000 Columbus $200,000 $0 $300,000 Hugo $1.600000 $0 $2,200;000 Lexington $200000 $0 $200.000 Lino Lakes $1,700,000 $0 $2.100;000 Joint Utility $1.400,000 $5:700,000 $0 Total $5,700,000 $5,700,000 $5,800,000 9.9.3 Anticipated Water Costs Anticipated water costs are shown in Table 9.4.
