科威特地处沙漠之中，常年高温、少雨、缺水。近日，记者到中建六局交通建设公司承建的南艾哈迈德 新城基础设施项目采访时发现，当前该项目最重要的一项任务就是"治水"。 一是治"地下水"。新城濒临波斯湾，项目现场地下富含渗透进来的海水。据介绍，现场地面以下平均1 —2米就是地下水。基槽一旦开挖，海水便汩汩冒出，并在潮汐作用下剧烈波动。积水最深处一度达到 2.5米。进场初期，潮汐地下水一度让项目施工陷入停滞。 经过多方研究，项目最终摸索出了6套降水（降低水位）方案，分别运用于不同工况。为了保护周围的 土壤及生态平衡，还采用了"地表回灌"措施：在降水管沟附近，用沙围出一个水池，收集泵站抽出的地 下水；这些水通过地表慢慢渗入地下，实现地下水的平衡；渗透的余水则用于路基和管沟回填的拌和用 水，也解决了沙漠地区取水难的问题。项目还建有一套小型海水淡化设备，将地下水处理后用于混凝土 等要求淡水施工的部位。 在一处基槽施工现场，记者看到两台挖掘机正在作业。而几米之外，一堆沙土相隔，可见半米深的渗透 水。项目总工程师杨贵虎说："这个对比恰好说明，治理好地下水对施工至关重要。" 二是治"雨水"。科威特常年干旱，淡水资源极度匮乏。一旦下 ...

Core Viewpoint - The construction of the South Ahmad City infrastructure project in Kuwait focuses on water management, addressing challenges related to groundwater, rainwater, and wastewater treatment [1][2][3]. Group 1: Groundwater Management - The project site has an average of 1-2 meters of groundwater, with seawater intrusion causing significant challenges during construction, including water levels reaching up to 2.5 meters [2]. - Six dewatering solutions were developed to manage groundwater levels, including surface recharge measures to maintain ecological balance and utilize excess water for construction needs [2][3]. Group 2: Rainwater Management - The project incorporates sponge city technology to collect and recycle rainwater, with plans to install approximately 76,009 rainwater collection units and over 264 kilometers of rainwater pipelines [3]. - The rainwater collection system is designed to support irrigation for green spaces, with a capacity to provide enough water for 50 acres of vegetation for a year after a single collection [3]. Group 3: Wastewater Management - The project will provide modern living conditions for at least 100,000 residents, integrating wastewater treatment and reuse into its design [3][4]. - Over 260 kilometers of wastewater pipelines will be installed, with a treatment capacity exceeding 50,000 cubic meters, allowing treated wastewater to be used for irrigation [3][4]. Group 4: Project Scale and Impact - The South Ahmad City infrastructure project covers an area of approximately 52.79 square kilometers and employs over 1,400 workers [4]. - The timely completion of the project is expected to alleviate housing pressure in the old Ahmad area, enhancing the living environment for local residents [4].

Core Insights - The recent ecological restoration efforts along the Yangtze River have garnered international attention, highlighting China's achievements in water resource management and ecological recovery [2][3][4]. Group 1: Ecological Restoration - The return of the endangered Yangtze River dolphin is seen as a significant indicator of ecological improvement in the Yangtze River, attributed to measures like the "Ten-Year Fishing Ban" [3][4]. - Reports indicate that the dolphin population has been observed over 40 times in the Wuhan section of the Yangtze River in the past five years, involving nearly 300 sightings, showcasing a remarkable recovery [3][4]. - The water quality in the Wuhan section of the Yangtze River has reached a 100% compliance rate, with biodiversity indicators such as the return of various fish species and migratory birds [4]. Group 2: Technological Integration - China's water management combines advanced technologies like quantum radar and digital twin systems for precise governance and systematic restoration [5][6]. - The Wuhan ecological environment monitoring platform utilizes 135 automatic water quality stations and drone surveillance for effective pollution tracking [5][6]. - The integration of satellite data, 5G technology, and traditional water management practices is noted as a novel approach that could provide new solutions for global watershed management [5][6]. Group 3: International Collaboration and Influence - China's water governance experience is being shared globally, with countries like Cambodia and Malaysia looking to adopt Chinese techniques for their own water management challenges [7][8]. - The collaboration between Kazakhstan and China includes comprehensive agreements on irrigation system reconstruction and water resource management [7]. - Observations from international experts highlight the potential of China's water management practices to inspire similar initiatives in other countries facing water crises [7][8].
