The input emergy of an advanced treatment plant for reducing the 1 kg of TN and TP was estimated 4.14E+14 sej/kg, 5.02E+15 sej/kg, respectively. In addition, the input emergy of constructed wetland for reduction of the 1 kg of TN and TP reduction was estimated to be 2.48E+14 sej/kg, 3.38E+15 sej/kg, respectively. The cost reducing 1 kg of TN and TP for an advanced treatment plant was estimated 197,466 won and 2,388,739 won respectively and constructed wetland was estimated 117,976 won and 1,609,213 won respectively. As a result, All of the emergy source of constructed wetland for reducing non-point source is renewable resource. If we use the constructed wetland, it results in enhancing economic value by reducing of non-point pollution, controlling a flood and providing the habitat of animals or plants. Improving water quality program in the Nakdong River Basin should be changed into an ecological treatment facilities from expansion of the sewage treatment facilities and advanced treatment plant using high cost and non-renewable energies.
