Yilan County is always proud of laying emphasis on “environmental protection”. In order to effectively improve the water quality of drainage basin, Yilan County has cooperated with the policies of Environmental Protection Administration to promote the pollution prevention and control work of rivers. But the opening of Hsuehshan Tunnel has driven the industry and commerce development and economic growth and meanwhile it has also derived many environmental pollution problems, so Yilan County is cautious and conscientious for various emerging environmental protection issues and hopes to consider both the environmental protection and economic development, which is also the topic needing to be valued and solved.

In order to effectively master and improve the water quality of various drainage basins, the methods of “inspection and control” and “guidance and improvement” are adopted concurrently to actively take the measures to prevent and control the pollution of public institutions and put an end to the discharge in violation of regulations, so as to reduce the deterioration of water pollution in various drainage basins and effectively lighten the load on water environment. In the past, people have dedicated lots of efforts to inspection and control of water pollution source, water quality monitoring of rivers and environmental education and advocacy and have also obtained good results.
