导语提要:8月31日,国务院常务会议听取城市地下管网建设情况汇报并作出专项部署。我国城市地下管网总长度约390万公里、规模居全球首位,"十五五"时期全国将建设改造城市地下管网约77万公里;会议要求从源头消除安全隐患,注重统一规划、突出建管并重,加强燃气、供水、排水、污水、供热等管网和综合管廊之间的衔接。
城市的"里子":390万公里管网的历史欠账
8月31日召开的国务院常务会议,专议题听取城市地下管网建设情况汇报。会议指出,地下管网是现代化基础设施网络体系重要组成部分,承担着供水保障、污水收集、雨水排放、燃气输送、热力供给等多重功能,要以系统思维加快推进建设,从源头消除安全隐患,提高城市功能品质。
作为城市的"里子",我国城市地下管网总长度已达约390万公里,规模居全球首位。中国城市规划学会地下空间规划分会副主任委员蒋应红解读指出,燃气、供水、排水、污水、供热等地下管网已基本覆盖大中小城市,为城镇化快速推进提供了坚实支撑;但在高速建设期过后,历史积累的结构性矛盾逐步显现,存量设施"带病运行"等问题日益突出——超期服役的管网、错接混接的排口、标准滞后的设施,都是悬在城市安全底线之上的隐患。
会议强调"从源头消除安全隐患",被业内视为治理逻辑的深层转换:将工作重心从传统的"事后应急抢修"前移至"事前风险预控与隐患排查治理",摆脱长期以来的"不坏不修、坏了再修"被动模式。这里的"源头",既是物理层面的隐患病灶,更是制度层面缺少周期性检测、强制性更新规范的系统漏洞。
"一次开挖、多网更新":统一规划破解工程碎片化
会议对建设方式提出三点明确要求:
- 注重统一规划——完善体制机制,结合实施城市更新行动,加强燃气、供水、排水、污水、供热等管网和综合管廊之间的衔接,提升整体效能。
- 突出建管并重——积极创新探索,实现可持续建设运营。
- 质量安全贯穿全过程——把质量安全贯穿建设运营全过程,打造安全可靠的民心工程。
其中"统一规划"的指向性极强:推动各地破除部门壁垒,实施多网协同改造,力争"一次开挖、多网更新",并把地下管网改造纳入城市更新、老旧小区改造和道路改造之中,避免重复开挖与工程碎片化,提升整体投资效益。"建管并重"则要求扭转"重建设、轻运维"导向,把运维模式、资金平衡、权责划分前置到规划决策环节,实现"建得成、管得好、长期受益"。
"十五五"77万公里改造:管网目标纳入城市更新规划
"十五五"时期,全国将建设改造城市地下管网约77万公里,相关目标已纳入《城市更新"十五五"规划》主要指标,实施任务列入市政基础设施提升工程,成为城市更新的重要抓手。资金端,2026年度中央财政支持实施城市更新行动已通过竞争性选拔确定部分城市,东部、中部、西部地区每个城市补助总额分别不超过8亿元、10亿元、12亿元;地方层面,吉林规划改造城市供热、供水、排水等管道1.4万公里,广西规划建设改造污水管网约1600公里、雨水管渠约2000公里。
对污水处理行业而言,管网是提质增效的"看不见的基础设施"——污水厂进水浓度偏低、汛期溢流污染的根源大多在管网。今年8月以来,监管与标准体系密集跟进:8月15日施行的《生态环境法典》将监管范围从末端出水向前延伸至管网收集、泵站调度、调蓄设施运维、污泥处置全链条,汛期进水水量波动不再简单作为污水厂出水超标的免责理由;8月28日住建部一次性公开3项城镇排水行业标准修订稿征求意见,覆盖排水管道CCTV检测与评估、管网病害等级判定、雨污分流施工质量管控等核心条款;8月主汛期台风"白海豚"及多轮极端短时暴雨又让厂网泵站联合调度的能力短板集中暴露。
"六张网"战略落子:从大规模新建转向全生命周期管控
This State Council Executive Meeting deployment also carries a deeper national strategic coordinate: this year's 4月28日 Political Bureau of the CPC Central Committee meeting explicitly proposed strengthening the planning and construction of the "Six Networks" — water network, new-type power grid, computing network, new-generation communication network, urban underground pipeline network, and logistics network, with 5月9日 State Council Executive Meeting making deployment arrangements, and 7月30日 Political Bureau meeting once again emphasizing solid implementation. The underground pipeline network is precisely the most foundational of the "Six Networks" — it determines the lifeline of the entire city.
Industry expectations indicate that as the State Council Executive Meeting deployment takes effect, China's urban underground pipeline network construction and renovation will shift from the past large-scale new construction expansion toward a model of systematic coordination, root-cause hazard elimination, integrated construction and management, and full life-cycle control that "prioritizes both stock quality improvement and incremental optimization." For pipeline network inspection and assessment, trenchless rehabilitation materials and equipment, smart pipeline networks (Digital Twin, AI monitoring), and "plant-network integrated" operation service providers, a certainty market anchored by top-level policy is opening up; for wastewater treatment operation enterprises, the systematic improvement of pipeline network quality will also directly translate into operational dividends of stable influent water quality and compliant effluent discharge.
