Intense rainfall led to flooding on Xinxing Road in the Shengang District and on Hemu Road in Qingshui District, Taichung City, affecting the safety of road users. To address this issue, the Taichung City Government's Water Resources Bureau secured NT$ 34.5 million for the “Shengang District Community Farm Roads (Nongzhong Shenqing 002 and Nongzhong Shenqing 018) Drainage Improvement Project.” This project, which commenced on June 9 of the previous year and was executed in phases, has already completed the first stage, which involved installing drainage culverts and paving approximately 304 meters of road on Hemu Road in Qingshui District. By the Chinese New Year holiday, the road has been opened for pedestrians and traffic, facilitating local residents' travel for a happy holiday season.
The Water Resources Bureau noted that the red soil layer on the Dadu Plateau is made up of gravel, silt and clay. During heavy rainfall, water mixed with red soil flows onto the roads. Combined with insufficient drainage capacity of the existing roadside ditches, this often leads to flooding. Last year, the Bureau successfully secured a subsidy of NT$30 million from the central government and raised an additional NT$4.5 million to fund the drainage improvement project. The project is being executed in phases. Following the Chinese New Year, the focus will be on completing the second phase, which involves constructing 440 meters of interceptor ditches (both open and closed) along Xinxing Road in Shengang District by the end of April, before the onset of the flood season. During heavy rainfall, these interceptor ditches and drainage culverts will redirect surface runoff into the Jiuzhuang River, mitigating flooding issues on Hemu Road in Qingshui District and XinXing Road in Shengang District.
The Water Resources Bureau added that in order to prevent soil and silt from accumulating in the drainage system during rainfall, the third phase of the project will involve simultaneously installing soil-blocking structures after the Chinese New Year. These structures, spanning 790 meters along both sides of the street in the upstream catchment area, will slow down surface runoff and prevent soil erosion in the agricultural lands. This measure is expected to reduce future maintenance costs and prolong the project's effectiveness. Once completed, the project will enhance the local drainage system, expectedly improving the flooded area by about 3 hectares and ensuring the safety of the local residents' lives and property.
