Innovation:

1. Dual-purpose detention basin, delivering environmental and economic benefits: In the design of the sediment settling and flood detention basin, this project took into account the need to reduce excavation area and avoid waste from secondary construction. The basin was therefore designed to serve dual purposes, both as a temporary construction facility and as a permanent flood detention structure. This approach reduced excavation volumes and effectively lowered overall project costs.
2. Use of on-site stone for slope protection, combining environmental sustainability, ecology, and aesthetics: Slope protection for the sediment settling and flood detention basin was constructed using screened soil and stone sourced on site. By fully utilizing local materials, the project aligns with government energy conservation and carbon reduction policies while achieving environmental protection, ecological compatibility, and visual quality.

Challenges:

1. Hillside worksite with narrow access roads: The project site is located on hillside terrain with narrow access roads, making material transport by large construction vehicles impractical. Small vehicles were therefore used, and traffic guidance and control were strengthened. On narrow sections, half-width construction was adopted, with steel plates installed to provide temporary access, ensuring that agricultural machinery and agricultural product transport could pass safely. This approach maintained construction progress while improving operational efficiency.
2. Proactive coordination to address land use and access issues: Most of the land required for this project is owned by Taiwan Sugar Corporation, with some parcels under private ownership. Through the assistance of local and central representatives, extensive communication and coordination were undertaken. Construction commenced only after lease agreements were signed and consent letters were obtained. Multiple construction briefings and coordination meetings were held, with schedules arranged to avoid peak farming seasons, thereby gaining the understanding and support of local farmers and community representatives.
3. Overcoming terrain constraints through the use of on-site materials: For the channel bed slopes of the sediment settling and flood detention basin, natural stone masonry techniques were employed using stones excavated and screened on site. This eco-friendly and cost-effective approach creates a porous environment that addresses site constraints while achieving environmental sustainability, cost-effectiveness, and structural integrity.
4. Integration with local landscape and industries: The sediment settling and flood detention basin was designed using ecological engineering methods that respond to local needs while integrating with the landscape. Reserved water storage capacity allows the basin to store surplus water during dry periods, increasing water availability for the Dapingding area. This improves water resource utilization efficiency and supports local economic and industrial development.

Comprehensiveness:

1. Site-adaptive stone masonry methods integrating environmental protection and ecology: For the slopes of the sediment settling and flood detention basin, natural stone masonry techniques using on-site excavated and screened stones were employed. This environmentally sound and cost-effective approach creates a porous environment that addresses site constraints while integrating ecological benefits with economic and structural safety.
2. Integration with local industries and landscape for shared benefits: The sediment settling basin was designed using ecological engineering methods and integrated into the local landscape. By storing surplus water during wet periods and supplementing supply during dry periods, the project increases water availability for the Dapingding area and improves the efficiency of water resource utilization. This, in turn, supports local industries and economic development, enhances rural quality of life, and creates shared benefits for all stakeholders.
    

1. During an on-site inspection conducted on March 17, 2021, by the Engineering Supervision Task Force of the Irrigation Agency, the project was recognized for its well-considered planning and design, effective implementation of the three-tier quality management system, and high construction quality, with sound overall performance. The project received a Grade A rating.
2. Located on hillside terrain with narrow access roads, the project faced challenging site conditions. The construction team demonstrated diligence and proactive management, maintained effective project control, and carried out thorough construction briefings and coordination. Through these efforts, the project successfully overcame adverse conditions, with no occupational safety incidents or public supervision reports recorded.
3. The project adopted ecological engineering approaches and made use of on-site soil and stone materials, achieving both ecological conservation and environmental protection. By integrating local landscape and ecological features, the project was harmonized with the surrounding environment and provides a venue for ecological and environmental education, with positive outcomes.
4. Overall planning for the project was comprehensive, integrating soil and water conservation measures with local ecological conditions. The project fully implemented the core principles of irrigation management encompassing production, life, and ecology, strengthened soil and water conservation, improved regional drainage, and achieved energy conservation, carbon reduction, and ecological sustainability goals.
