This project runs environmental data comprehension and updating, analysis of river water and polluting sources, and estimation of emission at source points on eleven primary rivers in Taiwan (Tamsui River, Nankan River, Lao-Jie River, Jhuoshuei River, New Huwei River, Beigang River, Ji-Shuei river, Yanshuei River, Er-Jen River, A-Gung-Dian River, and Love River), then summarizes the promotion of current strategies for pollution control, and tracks and reviews the annual and stage goals of the tasks of pollution control plan. Working with the analytic results of water quality and amount survey in primary river branches, water features and regional environment, the Project also reviews the pollution reduction strategies by modification or new recommendations, and assesses the benefits of water improvement by simulating with water quality models. The related control strategies include construction of sewer systems, implementation of dry-weather sewerage interception facility, promotion of in-situ treatment facilities for water purification, reinforcement of checking and control of polluting sources, reinforcement of counseling in proper treatment of wastewater by dairy industry, and promotion of clean pigsties and assessment of biogas center setup. in order to make the control measures happen, regular meetings on the supervision and coordination in the pollution control plans in the 11 primary rivers are held to bring together the consensus of the relevant authorities to review and modify the pollution control strategy and water improvement goals on a rolling basis. Screening of two river sections with heavy metal pollution is made from the results of historical analysis of water with heavy metals, whereby to draw up strategies for reduction and management of heavy metal pollution. Additionally, the control plan of 18 central-administered rivers is reviewed and tracked for executive results.
Project analyzes the tendency of water changes in the nation’s 50 rivers and 11 primary rivers in the recent five years and 2014, and reviews the accomplishment in the yearly goals of vision of Executive Yuan-approved project of rivers “without hypoxia and smell”. Screening of critical water monitoring stations in 11 primary rivers is further made to analyze the polluting sources and the control measures at these stations and to estimate the amount of pollution needing reduction and draw up strategies for pollution reduction, as well as predict the effectiveness of water improvement by using water quality simulation.
This project gathers information on the environmental condition, operation and maintenance and benefits of environmental improvement; holds one seminar on operation and maintenance of un-polluting artificial wetlands, while summarizing the promotion of construction and executive results of river pollution control by local governments on EPA subsidies. The web pages of on-site water purification in the basins of Tamsui and Er-Jen Rivers are updated on monthly basis, with additional information on three newly completed sites posted on the website. The project gives cooperation on other activities including meeting on primary rivers, site surveys and visits.
