However the Pittsburgh municipal government has informed PA that a surcharge of $5 per thousand cubic liters will soon be imposed for the discharge of this waste. This has prompted management to evaluate the desirability of treating its own liquid waste. P12-29. LO2, 3, 8 MBC A proposed system consists of three elements. The first is a retention basin, which would permit unusual discharges to be held and treated before entering the downstream system. The second is a continuous self-cleaning rotary filter required where solids are removed. The third is an automated neutralization process required where materials are added to control the alkalinity-acidity range The system is designed to process 600,000 liters a day. However, management ant only about 250,000 liters of liquid waste would be processed in a normal workday. The company oper- ates 300 days per year. The initial investment in the system would be $900,000, and annual operating costs are predicted to be $162.000. The system has a predicted useful life of ten years and a salvage value of $70,000 Required a. Determine the project's net present value at a discount rate of 16 percent. b. Determine the project's approximate internal rate of return. (Refer to Appendix 12B if you use the table approach.) c. Determine the project's payback period
