Taipei Water Department

The Taipei Water Department and its engineering team have been recognized for their commitment to environmental sustainability and carbon reduction. Despite substantial engineering obstacles, the team has upheld outstanding quality in managing two major projects, the "1st Clean Water Transmission Mains Backup Pipeline Turnkey Project" and the "2023-2024 Hot Tapping Connecting and Stopping Valve Installation Project." These efforts have earned them the prestigious 2024 Taipei City Distinguished Public Construction Award. Deputy Mayor Lee Shu-chuan presented the awards today (16th) at the Guoguang Hall of CPC Corporation, Taiwan, with Deputy Commissioner Chen Ming-chou and Engineering Corps Chief Chen Wei-cheng receiving them on behalf of the Department.

According to the Taipei Water Department, the 1st Clean Water Transmission Mains Backup (PCCP Along Chenggong Road of Zhonghe and Yonghe District) Pipeline Turnkey Project was initiated due to the over 40-year-old 1st Clean Water Transmission Mains, which required a backup to mitigate the impact of future MRT construction and reduce water supply risks. Utilizing double shield tunnel boring machines to accelerate the project’s progress, the completed pipeline will establish a dual-pipe support mechanism, significantly reducing potential water supply risks and costs, thereby enhancing the stability and safety of the water supply in the Greater Taipei area. The project’s use of environmentally friendly shield tunnel boring methods, which minimized excavation and overcame geographical obstacles, along with the sustainable design of the pipeline, earned it the 2024 Taipei City Distinguished Public Construction Award, under the Waterworks Engineering Category (1st Class Engineering Project).

The "2023-2024 Hot Tapping Connecting and Stopping Valve Installation Project" involved the Department’s self-designed and supervised small-diameter hot tapping construction method, which allows construction without the need for water supply shutdowns. This method effectively reduces construction risks, saves water, conserves energy and cuts down carbon emissions. After installation, it enables flexible water supply management and accelerates pipeline replacement work. When combined with pipeline network improvement and district metering area (DMA) initiatives, reduces the impact of large-scale water outages. The project was self-designed and supervised by the Taipei Water Department, in collaboration with domestic and Japanese specialists. By incorporating Japanese technology and expertise, the Department successfully facilitated the local production and supply of the hot tapping method in Taiwan. In recognition of its achievements, the project was also recognized with the 2024 Taipei City Distinguished Public Construction Award, under the Waterworks Engineering Category (3rd Class Engineering Project).

The Taipei Water Department explained that the two award-winning projects have significantly enhanced the safety and stability of the overall water supply system in the Greater Taipei area. During construction, the projects minimized external impacts, established new protective systems for high-risk operations, and implemented comprehensive safety management practices. The design and supervision processes also contributed to the continuous development of the Department’s staff engineering expertise, ensuring the sustainable advancement of water infrastructure capabilities. Moving forward, the Department is committed to further improving its hardware infrastructure and fostering the growth of its technical talent, all in pursuit of providing residents with the highest quality of water in Taipei.
