The Dingzhonggu Canal is located within the jurisdiction of Yangmingshan National Park. During the planning phase, a simple soil and water conservation assessment had to be conducted in cooperation with the park management. During construction, the material delivery point was 500 meters away from the work site, requiring a climb of 50 to 100 meters, with most materials being manually transported. The project site is situated in a remote mountainous area, with winding and steep footpaths for manual transport. Due to national park restrictions, the use of large machinery was prohibited, making material transportation challenging. Delivering and pouring concrete on-site was particularly difficult, and setting up pump trucks with piping was not feasible. These factors significantly increased the complexity of construction, elevated project costs, and put pressure on the project timeline. Given these challenging conditions, it is remarkable that the canal has been maintained in a smooth and winding state. This achievement is truly commendable.
