[Reporter Yang Xinhui/Taipei Report] On October 16 last year, Taipei City was hit by heavy rain due to the circulation of Typhoon Nisha. Hundreds of vehicles outside the embankment of Bailing Bridge were soaked in water. Taipei Mayor Ke Wenzhe was in the auxiliary election in other counties and cities, and it was canceled at night The rush back to Taipei caused public grievances. Now the Taipei City Water Conservancy Department has combined the alarm system and monitoring system with the official LINE account "Lian Lian Shui Lv Taipei Water Conservancy" to provide information on rainfall, river water levels, storm sewer water levels, pumping station status, flooding points, etc. It can even simulate the flooding situation, so that the public can grasp the water situation in real time.

Huang Yiping, director of the Taipei Municipal Bureau of Public Works, said that since Taipei Mayor Jiang Wanan took office, he has continuously emphasized the need to build Taipei into a disaster-resistant and resilient city in order to ensure the safety of citizens' lives and property, and to respond to the impact of extreme climates and move towards the goal of sustainable development. Forward, as long as you subscribe to the LINE official account "Lian Lian Shui Lv Taipei Water Conservancy", you can enjoy services such as location query, local water conditions, CCTV images, evacuation information, disaster notification, siren subscription, etc., and grasp various water conditions, at critical moments Receive instant rain alerts.

Chen Guozheng, director of the Water Conservancy Department of Taipei City, said in an interview that whenever there is a heavy rain, the Water Conservancy Department has a detection system to obtain the first-time water conditions, and will immediately announce the situation through "Lianlian Water Green Taipei Water Conservancy", so that the public can also take precautions in advance , to reduce the possibility of disasters; in addition, in the past, people parked their vehicles outside the embankment, and after the city government issued an ultimatum message of "closing the door", it would be towed a few hours later. After hours, it will be towed immediately, and the car will be fined if it is not moved.

Chen Guozheng pointed out that in the past, counties and cities used to report the amount of rainfall to the outside world, but now the "Love Water Green Taipei Water Conservancy" combines the flood simulation system to announce possible floods, which is used for the first time in Taiwan. As for the system development, it is in response to extreme weather Since June last year, it has also prevented too many people from calling 1999 when floods occur, but the city government has insufficient capacity to respond.

The Taipei City Water Conservancy Department added that "Lian Lian Aqua Taipei Water Conservancy" has officially opened the subscription function. Click "Subscribe Siren" to get the current location and provide a list of administrative mileage. You can subscribe according to your needs. To achieve the goal of localizing the water regime, after subscribing, you can easily obtain the local water regime. When there is a water regime warning in the target area, the system will actively push the alarm information and provide relevant contingency measures.

In addition, the Sanitation Works Department built a "computer-aided operation and management system for sewage sewers". After testing and learning, the software system has gradually shown its benefits, which will effectively reduce the occurrence of sewage manhole cover gas flushing cases in Beishi, and "cure the symptoms and cure the root cause" Strategy.

The Ministry of Sanitation explained that the "palliative treatment" is aimed at the old-style frame covers where the main and secondary trunk pipes downstream of the sewage sewer system are prone to air scour, and the priority is to update them with the new "uplift-resistant frame covers" that meet the CNS standard. When the air inside the manhole is damaged When squeezed and impacted, the frame cover floats up to 2 cm, and automatically exhausts and releases the pressure before returning to its original position, which can prevent the frame cover from flying or bouncing.

The Health and Works Department further pointed out that "to cure the root cause" is to use technology to screen instead of manual inspections, install mobile water level gauges in the branch pipe network upstream of the sewage sewer system for monitoring, find out the hot spots where the water is full, and then carry out the improvement project; In addition, a water level gauge is added to complement the pipe network information, and more accurate weather forecasts will be introduced. Based on the experience of each heavy rain event, the system parameters will be reviewed and corrected in a rolling manner to improve the prediction accuracy and provide reference for personnel operations.

The LINE official account of the Taipei City Water Conservancy Department, "Lian Lian Shui Lu Taipei Water Conservancy", provides functions such as rainfall, river water level, rainwater sewer water level, status of pumping stations, flooding points, etc., so that the public can grasp the water situation in real time.
