This program is commissioned by the Environmental Protection Administration (EPA) of the Executive Yuan in implementing forward-looking river water quality and environmental management in central Taiwan, with the results obtained as follows:
(I) In addition to assisting in tracking and evaluating the forward-looking program’s engineering and ecological inspections in various counties and cities in central Taiwan, the team also worked with government agencies to review and subsidize local governments to improve the water environment. The team's key tasks included assisting in reviewing grant proposals, examining their design content, budget adequacy and compliance with regulations. This year, it aided the Yunlin County Water Resources Department in applying for three forward-looking infrastructure projects and one ammonia nitrogen reduction project, and assisted in reviewing the Changhua County forward-looking batch 4 Erlin River project, and provided suggestions for refinement. Moreover, to step up publicity benefits of the forward-looking projects in counties and cities across central Taiwan, the team has finished the filming of three Bright Spot Project documentaries, on the Tungta River, Han River and Green River projects in Taichung, with a 10-minute full version and a 2-minute highlight version each, and produced the “forward-looking water and environmental projects for dummies” in an easy-to-understand way for the public in the form of the three four-panel comic strips on Environmental Aquaman, the Tungta River water environment remediation project, and the water environment remediation project for Beigang’s cobble contact treatment factory and Sinjie’s large open drainage channel, while providing data on Lukang River for making booklets for dummies.
(II) In order to enhance the construction quality and schedule control of various water quality improvement and environmental protection facilities funded by the EPA, the team has conducted 24 water environment improvement project supervision operations and compiled an annual implementation results report regarding common negligence on the part of government authorities in charge of projects, design supervisors and construction contractors (on site), for reference by the EPA and local authorities and relevant practitioners.
(III) The team performed 66 water quality and water quantity replenishment surveys (including 30 heavy metal tests) in two key river basins, namely Hsinhuwei River and Beigang River, and proposed relevant water quality improvement strategies based on these surveys. In order to reinforce the effectiveness of water quality remediation at critical monitoring stations under the central region program, the team prepared a monthly summary of deteriorating conditions at monitoring stations and conducted screening of businesses under management for potentially polluting sources upstream for the environmental protection inspectorate's enhanced audit and control. The team also assisted with collection and treatment by large farms in small ones’ place near Taiwan Sugar Co Huwei Pig Farm, the negotiation with business entities under management on the reduction of the pollution in the Chungkang River basin upstream of the Nankang River Bridge, and the co-ordination meeting on the pollution remediation of Beigang River and Hsinhuwei River, with a view to improving the water quality in the key river sections. Furthermore, the group assisted in the delineation of the sewage collection areas affected by the critical pollution monitoring stations at Hsinhuwei and Beigang rivers and the identification of the sewage collection areas upstream of the water quality monitoring station as well as the creation of a Beigang River hydrological model, which is used to estimate the flow rates of the whole river basin and to develop a reduction plan based on the model.
(IV) The team co-organized last year's (2019) performance assessment award ceremony and experience exchange seminar, this year's (2020) river pollution remediation assessment plan results review meetings, and co-hosts next year's (2021) draft assessment plan discussion; assisted in the initial review of the current year's (2020) pollution reduction plan at the critical monitoring stations, the tracking and evaluation of the effectiveness of the implementation, and the revision of the scoring principles for the next year's (2021) reduction plan, in order to establish the criteria for county and municipal governments to promote the prevention and control of river pollution, and to boost the effectiveness of local governments in pushing the actual reduction at critical monitoring stations within their jurisdiction.
(V) In an attempt to look into the composition of raw wastewater from existing flat and raised-bed barns in Taiwan, six samples of livestock raw wastewater have been taken and analyzed for six elements and three components for a pilot project on the thermal chemical energy conversion of livestock feces and urine in the southern region. Through on-site visits, the team assisted with matching among livestock farms in the vicinity of the Taiwan Sugar Co Huwei Pig Farm, which were willing to cooperate with the "large farms undertaking treatment in place of small ones" principle, and held discussions and meetings/interviews among key figures, in an effort to expedite the resourcezation of livestock feces and urine in the sewage collection areas at critical monitoring stations.
(VI) The team assisted in tracking and evaluating the total volume control projects in Miaoli County’s Fangli River, Taichung City’s Tali River and Chantsoyuen Irrigation Canal, and Changhua County’s Tunghsi No.2 and No.3 irrigation canals and Papao 1st Irrigation Canal in counties and cities across central Taiwan, and helped to conduct a "Planning, Explanation and Consultation Meeting on Total Water Pollution Control in the Chungkang River basin, Miaoli County" to consolidate data from inspection of businesses under management and water quality for evaluation. For suspended solids and other water quality worsening items at monitoring stations, the team also combined the three-dimensional inspection function of the unmanned aerial vehicle (UAV) to conduct three-day drone inspections of Chungkang River in Miaoli County, Wu River in Taichung City, and Hsinhuwei River in Yunlin County, and performed three-dimensional and real-time pollution investigations to maintain the water quality of rivers and streams in central Taiwan.
The work team has successfully completed the above-mentioned tasks, and brought forward relevant improvement actions and strategies based on the results and bottlenecks encountered in the implementation process, as well as proposals such as promoting the utilization of livestock feces and urine resources, planning a total volume control area, and carrying out in-depth collection of relevant hydrological data.
