Yilan County is always proud of its focus on “environmental protection”. To effectively improve the water quality in the drainage basin, it has, in cooperation with the policy given by the Environmental Protection Administration, been promoting the river pollution prevention and control work in recent years. However, with the industrial and commercial development and economic growth after Hsuehshan Tunnel is open to traffic, many environmental pollution problems have been caused, and moreover, Yilan County is cautious and conscientious to various rising environmental protection issues, and excepts to consider the development of environmental protection and economy, which needs to be emphasized and solved. In Yilan County, there are 7 important rivers and brooks, namely, Dezikou Brook, Lanyang Brook, Dongshan River, Xincheng Brook, Su’ao Brook, Nan’ao Brook, and Heping Brook, with a total area of the county up to 2,143.6km2; and Yilan County administrates about 551 wastewater (sewage) causes and sewage systems. To effectively grasp and improve the water quality of each drainage basin, through the methods of “regulation under audit” and “improvement under guidance”, Yilan County has actively taken the pollution prevention and control measures and stopped illegal emissions, so as to reduce the water quality deterioration conditions of each drainage basin and further to effectively reduce the load of water environment.
