Core Viewpoint - The water supply transformation in Yuncheng County, benefiting 420,000 residents, is a significant achievement driven by Heze Ruiyuan Company, showcasing their commitment and innovation in improving public welfare [1][4]. Group 1: Project Overview - The water source replacement project, covering 22 towns and 439 administrative villages, is nearing completion by July 2025, achieving a 100% water quality compliance rate [1][8]. - The project addresses severe water quality issues, including high salinity and fluoride levels, which posed health risks and hindered local ecological and economic development [4]. Group 2: Implementation Strategies - Heze Ruiyuan Company established a special task force with local government and technical teams to implement three key measures for project advancement [6]. - New corrosion-resistant materials (PCCP and PE pipes) were utilized to enhance pipeline durability, alongside an intelligent scheduling system for real-time monitoring of water pressure distribution [6]. - A "daily scheduling, weekly summary" mechanism was established to strengthen process management, resulting in the completion of six months' worth of work in just four months [6]. Group 3: Project Impact - The project has laid 631 kilometers of pipelines, ensuring comprehensive coverage of Yuncheng County's 22 towns and streets [8]. - The water source replacement will provide clean and safe water to 420,000 residents, with fluoride and hardness levels reduced by 80%, and an expected 35% decrease in waterborne disease consultations [8]. Group 4: Long-term Sustainability - Heze Ruiyuan Company has developed a "construction and management integration" service system to ensure long-term water quality safety and transparency for residents [9]. - Monthly third-party water quality testing and advanced real-time monitoring systems are in place to detect and respond to any anomalies promptly [9]. - The introduction of the "Yunzhou Water" WeChat mini-program and hotline services enhances public access to water quality information and service requests, significantly improving resident satisfaction [9].

指标性缺水与刚性需求矛盾突出。国务院实行最严格水资源管理制度，要求严格控制取用水总量，甘肃 省政府将全省用水总量指标分配到各市州。以张掖为例，全市2015年用水总量指标23亿立方米，2020年 减少到20.11亿立方米，减幅12.6%。而为保障粮食安全，全市粮食种植面积由2015年282.36万亩增加到 2020年330.15万亩，增幅16.9%。同时，随着经济社会发展，生产、生活、生态用水持续增加，水资源 供需矛盾日益突出，总体上地下水的取水量大于补给量。 综合分析来看，甘肃河西地区地下水位下降的原因主要包括以下几方面。 河西地区水资源先天不足。河西地区属于内陆河流域，年均降水量约36毫米—200毫米，年蒸发量却高 达2000毫米—3500毫米，降水量不及蒸发量的1/10。一方面，水资源禀赋条件差、先天不足，水资源总 量42.75亿立方米，人均水资源量990立方米，约为全国平均水平的56%，资源性缺水问题十分突出。另 一方面，水资源时空分布不均衡，6月—8月降水占全年降水的59%，降水和灌溉时段错峰，极易造 成"卡脖子旱"，地下水成为抗旱的主要灌溉水源。 河西内陆河两水转换频繁。受河西内陆河流域特殊的水文地 ...
