A 50-mgpd (US) water treatment plant is proposed in 2020 for Washington. A 60-mgpd plant using the same treatment process was built in 2013 in Vancouver. Make a conceptual cost estimate based on the following information: Poor site condition in Vancouver required an additional $3,000,000 for foundation which is not anticipated for Washington. Assume the size exponent m- 0.67 Assume inflation will persist at an average of 4% per annum. Assume the location index for Vancouver is 1.17 and 1.24 for Washington A new High pressure filter process will be added at Washington at an additional cost of $4,000,000. The construction period for the new plant will be in Winter. Assume an increase of construction cost by 12%.
