Typhoon Doksuri had remained distant, but yesterday afternoon (29th), severe convection and torrential rains struck both remote and urban districts. The rainwater sewage engineering project on Meicun South Road in the South District, completed in February this year, has played a role in flood control. In the past, Meicun Road, Funan Street, and Meicun South Road in the South District of Taichung City were prone to flooding because of heavy rain. Last year, the city government invested about NTD 26 million to build a new rainwater sewer 515M, which has improved the flood control capacity of the area and solved the problem of easy flooding.

According to the Water Resource Bureau, 2021 torrential rains launched the community drainage project on Chenggong East Road in Wuri due to flooding caused by illegal construction and blocked drainage channels. Influenced by heat convection in the afternoon yesterday, the cumulative rainfall in three hours reached 143.5 mm, and the maximum rainfall intensity per hour was 73 mm, which exceeded the 2021 flood rainfall (56.5 mm). However, there was no report of flooding in the community, which shows that the drainage works are working! The Water Resource Bureau sent personnel to inspect the improved drainage waterways for caution after the typhoon. The pathways were found to be unobstructed, displaying no signs of silt accumulation or blockage.

Furthermore, the recent years' occurrences of extreme weather and torrential rain have inflicted significant damage to the lower structure of the downstream channel of Nantun River Drainage Yongshun Road, specifically the segment extending from Renben Bridge to the fifth section of Huanzhong Road. The Water Resource Bureau of the Taichung City Government prepared NTD 11.25 million for the reconstruction project to avoid the continuous expansion of the disaster. Completed the project in late April this year, it has improved the length of about 500 meters to ensure the drainage function of the river. Yesterday was a heavy rainfall event. However, the Nantun River drained smoothly, and there was no flooding in the surrounding area, clearly showing the project improvement benefit.
Shih-Yi Fan, Director of the Water Resource Bureau, has highlighted that in the wake of recent years' encounters with extreme weather, efforts have been made to bolster Taichung City's flood disaster preparedness and resilience. To this end, the Water Resource Bureau has established a comprehensive three-dimensional water regime monitoring network. More than 300 hydrodynamic monitoring stations have played effectiveness in yesterday's torrential rain. The Water Resource Bureau will immediately coordinate with the District Office to assist in supplying sandbags and notify the police station for traffic control after receiving the flood detection warning. It effectively shortens the disaster notification and response time and reduces the risk of disasters. This year, the bureau will deploy another 172 flooding sensing stations to increase the density of flood prevention monitors to improve the water monitoring network and make citizens feel more at ease through digital protection.

The Water Resource Bureau further articulated their intention to establish an urban vision of "resilient coexistence with water" for Taichung City, in direct response to the potential threat of water-related disasters stemming from brief yet intense rainfall episodes in the future. Besides preparing for flood control, the city government will continue to actively arrange various flood control facilities, such as accelerating the promotion of rainwater sewage engineering projects and continuously improving the intelligent flood control network. It will enhance the drainage capacity of various regions and improve the flooding situation in low-lying areas, strengthen the ability of Taichung City to defend against heavy rainfall and maintain the safety of citizens' lives and property.
