The drains and rivers in the main areas of this county are the main source of irrigating water in this county. The maintenance of water quality is thus the more important considering the protection of people’s life and property as well as the maintenance of environmental safety. The Environmental Protection Bureau of Changhua County thus planned in 2009 on facilitating the “2009 Project of Pollution Source Control and Prevention of River & Ocean Pollution” (hereinafter called the “Project”) hoping to implement the system of permit control. The pollution by the polluting sources in the County will be fully heeded and continued to be reduced, the illegal discharge and secret piping will be blocked, and their specific sources will be traced and reported for crack-down, to really make the improvement on water quality in all rivers in the County happen. So, the whole environmental quality and the water-front space will be upgraded, offering all the County’s citizens the clean and clear natural river ecology.
