Core Viewpoint - The completion of the main construction of the Guanlu Reservoir marks a significant milestone for water resource management in Shandong Province, enhancing water supply capabilities for Qingdao and the Jiaodong Peninsula [1] Group 1: Project Overview - The Guanlu Reservoir, located downstream of the墨水河 in Jiaozhou, Qingdao, is the largest newly built reservoir in Shandong Province in recent years, with a total investment of 9.145 billion yuan and a total storage capacity of 211 million cubic meters [1] - The reservoir is expected to begin water storage in the second half of 2026, contributing to the construction of a modern water network in the province [1] Group 2: Benefits and Impact - Upon completion, the reservoir will alleviate the current reliance on single-channel and overloaded water supply systems, creating a dual-source complementary water supply structure that significantly enhances water resource allocation and supply security for Qingdao and the Jiaodong Peninsula [1] - The project aims to support high-quality economic and social development in the region [1] Group 3: Construction Challenges and Innovations - Since the project commenced in 2023, it has faced challenges such as high groundwater levels, limited effective construction time, and cross-seasonal operations, yet it has successfully tackled significant construction difficulties [1] - The construction process has implemented a quality closed-loop system focusing on "model guidance + standard guidelines + smart construction," promoting green construction practices and resulting in over 10 patented innovative construction methods [1]

Core Insights - The construction of the "super reservoir" in Qingdao, with a total investment of 9.145 billion yuan and a total capacity of 211 million cubic meters, is crucial for the city's future development and water security [2][3][6]. Group 1: Project Overview - The project, known as the Guanlu Reservoir, commenced full construction in December 2022 and is currently in the final stages of development [2]. - The reservoir's design capacity is classified as large (Type II), with a total capacity of 211 million cubic meters, equivalent to four Laoshan Reservoirs [4]. - The construction includes various components such as embankments, pumping stations, and river channel diversions, with innovative technologies employed to enhance durability and adaptability [4]. Group 2: Water Resource Challenges - Qingdao faces significant water resource shortages, with per capita water availability at only 186 cubic meters, far below the national average [3]. - The city's current annual water supply capacity is 670 million cubic meters, but projected demand by 2035 is expected to reach 1.6 billion cubic meters, resulting in a shortfall of 930 million cubic meters [3]. Group 3: Benefits and Impact - Once completed, the Guanlu Reservoir will provide an annual water storage capacity of 600 million cubic meters, serving as a vital water source for Qingdao and surrounding areas [6]. - The reservoir will enhance regional water supply security, supporting urban and industrial water needs while addressing the water demands of neighboring cities [6]. - The project aims to transform Qingdao's water supply system from a single-channel approach to a dual-insurance model, significantly improving strategic water reserve capabilities [6][7]. Group 4: Construction Progress - As of now, the project has completed an investment of 6.417 billion yuan, with major construction milestones nearing completion: embankment filling at 99%, pumping station at 93%, and the connecting line at 97% [7]. - The main construction is scheduled for completion by the end of 2025, with full project completion expected in 2026, marking a significant advancement for Qingdao's high-quality development [7].
