A large water utility is planning to upgrade its SCADA system for controlling well pumps, booster pumps, and disinfection equipment for centralized monitoring and control. Phase I will reduce labor and travel costs by $28,000 per year. Phase II will reduce costs by an additional $20,000 per year, that is $48,000. If phase I savings occur in years 0, 1, 2, and 3 and phase II savings occur in years 4 through 10, what is the present worth of the upgraded system in years 1 to 10 at an interest rate of 8% per year?
