The City of Bourbonnais plans to construct a water purification facility that requires $1,000,000 investment in the beginning and $20,000 O&M costs per year. The city will expect additional revenue of $70,000 per year from residents.
Assuming the city’s MARR is 10% compounded yearly and the facility is handed over after 20 years to a utility company that would pay $120,000 for the facility, compute the net present worth of the project and determine if the project is economically worthy? . [Show all factor notations involved in the calculation.]
First cost = $ 1,000,000
Annual O&M cost = $ 20,000
Annual Revenue = $ 70,000
Sell after 20 year for $ 120,000
Interest = 10%
Calculating the net present worth of the investment
The net present worth of the cash flow is negative therefore, the investment is not beneficial.
Hence, the project is not economically worthy.
