1. Project Background: The Guanshan Canal Main Canal, with a total length of 18.8 km, was equipped with a concrete lining in 1954. After many years of use, the structure deteriorated significantly. To maintain the irrigation functionality of the Guanshan Canal Main Canal, phased improvements were carried out over several years.
2. Construction Location: Taitung City, Taitung County.
3. Total Project Cost: NT$8,926,000.
4. Construction Period: From November 19, 2008, to April 30, 2009, with a total duration of 163 calendar days.
5. Project Details: main line lining for 293 meters, underground culvert for 12 meters, management road for 293 meters, landscaping work, retaining wall on the left side of the management road for 283.5 meters, wooden-style railing (including foundation) and cantilever retaining wall for 297.6 meters, and other related works.

1. Wooden-Style Railings: The railings along the lining were crafted in a wooden style, made on-site by hand to follow the curves of the channel, offering a unique appearance compared to typical factory-made designs.
2. New Management Road: The land alongside the canal was overrun by illegal farming activities, making management difficult. After the land was reclaimed, a management road was constructed.
3. Naturally Winding Irrigation Channel: The design followed precise measurements of elevation and curvature, resulting in a natural, winding appearance for the channel.
4. Landscaping and Greening: The surrounding area was beautified with trees, shrubs, and grass, softening the rigid appearance of the structure and attracting more birds, insects, and other wildlife, enhancing the local ecosystem.
5. To complement the overall aesthetic of Ruifeng community, the retaining walls were designed using decorative formwork.
6. The project connects and integrates the entire 18.8 km length of the irrigation channel and management road.
7. Planning, design, supervision, and safety measures were meticulously implemented to minimize environmental impacts.
8. The project showcases a space rich in ecological diversity, with beautiful scenery, greenery, and water resources for both recreation and education.
1. The project integrates with the community to provide irrigation functionality, a recreational space for local residents, and an excellent engineering environment that is easy for the Irrigation Association to manage and maintain.
2. The project minimizes sediment build-up in the channel, reducing maintenance and management costs. It also addresses leakage issues, shortens water delivery times, and improves irrigation efficiency.
3. The project connects with the main canal’s long-term improvement plan, and construction has been well-managed with no safety incidents.
