The 1st stage of Tamshui River Pollution Control Sequent Implementation Plan will be expired at the end of 2007; therefore, EPA raised this project to speed up the water quality improvement of the severely polluted sections and to develop the 2nd stage plan. There are three main achievement of this project. First, this project develops the strategies to improve the environment of three river bank recreation parks, the Da-Chia Park, the Hwa-Chung Park, and the Ba-Li sailboat dock. The main objective of the environmental improvement is to satisfy the sensory perception of the community, including no odor, no litter and water clarity. The strategies of the Da-Chia Park include the sludge cleaning, the upgrading of Nei-Hu WWTP nitrification performance, and the operation of existing DWF interception stations. The strategy of the Hwa-Chung Park is the supervision of sand and stone yards. The strategy of the Ba-Li sailboat dock is the litter cleaning. Secondly, this project develops the strategies to improve the water quality of severely polluted river sections. The strategies of Hsin-Tein creek are to accomplish sewer connection of 32,000 households per year, and to operate seven existing and planning DWF interception stations. The strategies of Keelung river are to accomplish the sewer connection of 13,000 households per year, and to operate nine existing and planning DWF interception stations. The strategies of Ta-Han creek are to accomplish the sewer connection of 5,000 households per year, and to build and operate both the Nan-Tz-Go and Si-San DWF interception stations. Additionally, the supervision of sand and stone yards, and the operation of onsite wastewater treatment facilities are also very important for the Ta-Han creek water pollution control. The strategy of Tamshui river is to accomplish the sewer connection of 12,000 households per year. Finally, after the goal of improving the severely polluted river sections accomplished, Taipei city government must continue the sewer connection of 20,000 households per year, Taipei county government must accomplish 40,000 households per year, Keelung city government must accomplish 2,000 households per year to meet the water quality criteria. Besides, Taipei county government must accomplish the wastewater treatment system for Sanshia and Yingge areas; and Taoyung county government must accomplish the wastewater treatment system for Shihmen and Puding areas.
