There are three major river basins in Hsinchu County (Touqian River Basin, Fengshan River Basin and Xinfeng River Basin), which start from the central mountain range and run westward through the hinterland of the jurisdiction, collecting domestic sewage, industrial wastewater and animal husbandry wastewater on the way , to the downstream alluvial plain and then to the sea. In recent years, due to the rapid development of county government and industry and commerce, the environmental load caused by human activities has intensified, which has also led to a sharp increase in river pollution incidents.
In order to understand the changes in water quality in the river basins of Hsinchu County and improve the discharge of river water pollution, the Environmental Protection Bureau of the Hsinchu County Government publicly selected technical consultants to handle the "110-year Hsinchu County Water Pollution Source Inspection and Water Sewage Fee Collection Review Plan and Animal Husbandry Wastewater Ammonia Nitrogen Recovery" The Promotion Plan and Water Pollution Prevention and Control Permit Examination Plan", in addition to continuing the previous control operations related to water pollution prevention and control, and through the management of special inspections, expert on-site counseling mechanisms, and facility function evaluations, etc., strengthen the control of public institutions. Encourage the industry to face up to the problem of waste water disposal in the factory, and prevent the occurrence of fluke mentality and illegal discharge. A summary of the implementation progress of the current operations (statistical period from January 1, 2011 to November 30, 2011) is as follows:
