Interviews were conducted with management officials of the plant and Bauchi State Ministry of Water Resources. From data collected N127,900,000 was revealed as annual cost of water treatment before pollution control. The research concluded that the method proved to be applicable in the study area but needs to be improved upon, to make the value estimates credible and reliable in developing economies. Among other things, culture, as reflected in management and attitude, had been a major cause, observed to be affecting the effectiveness of the method in the study area. Finally, recommendations were made for the discounting of economic benefits
