You are considering buying pumps to handle 1.5 ML/d. Your company's risk management strategy calls for two units each capable of handling three-quarters of the total flow. You have a recent estimate for a pump that give a capital cost of $300,000 for a unit with a capacity of 500 kL/d. What is the total installed cost, if installation costs are twice the cost of the equipment? Assume a scaling factor of 0.7.
