Abstract
The two strategies to prevent and treat water pollution problems are using administrational control or economical systems. From the experiences of European countries, those combine the above two strategies can improve the pollution-reduction effect, while using only administrational control can’t do so well.
In Taiwan, there were many studies about the effluent charge, and the rate they suggested depend on their point of view. This study considers the inflating of currency and referring to the way how the Environmental Protection Administration decide the rates, then obtains the rates per polluting unit from 2003 to 2005 are 920NT, 935NT and 950NT accordingly.
Because the levying objects at the first stage are industries and the sewer systems of industrial area, this study choose the industries with more complete data of water quality and pollution costs , then construct their Marginal Water Quality Abatement Cost curve to analysis and evaluate how much can the pollution-reduction improve, and the economical effect to those delivering effluent charges.
The results show that the food-manufacturing industries will raise the amount of pollution, while the textile-manufacturing industries, leather-manufacturing industries and chemical plants will reduce it. And the effluent charge delivered by each kind of industries is lower than 1% of its gross profit, means that the rate may be accepted by those delivering them. By comparing with other countries comes to the results that the rates of recent years are suitable. Because the levying objects at the first stage also inclusive of the sewer systems of industrial area, this study calculate their cost to process pollution and shows that the rate has fewer attraction for them to improve pollution-reduction.
