国家公园管理局（NPS）聘请CDM设计和建造改进项目 其Flamingo供水系统，包括完全更换其配水系统 系统弗拉明戈地区是大沼泽国家公园内最大的发达地区 （公园），包括游客中心、餐厅设施和住房 来自世界各地的游客。现有的配水系统由25000个组成 直线英尺6英寸、4英寸石棉混凝土和聚氯乙烯水管。这个 大部分配电系统建于1947年。 供水系统更换计划几乎完全采用非开挖方式 施工，最大限度地减少对宝贵的环境敏感和不可替代资源的影响 自然资源；主要的配电线路被高密度电缆取代 聚乙烯（HDPE）管道采用爆管法。聚乙烯管道 进行预氯化消毒，并在消毒前对地上管线进行细菌清理 安装。这使得新线路可以立即投入使用 尽量减少对公园游客和居民的干扰。这个项目是最大的 迄今为止，这项技术在北美的总线性镜头中的应用。 本文记录了新管道的安装情况，重点介绍了 使用爆管和预氯化技术。

The National Park Service (NPS) engaged CDM to design and construct improvements to its Flamingo water system, including the complete replacement of its water distribution system. The Flamingo area is the largest developed area within Everglades National Park (Park) and includes a visitor's center, restaurant facilities, and housing to accommodate visitors from all over the world. The existing water distribution system consists of 25,000 linear feet of 6-, 4-inch asbestos concrete and polyvinyl chloride water mains. The majority of the distribution system was constructed in 1947. The plan for the water distribution system replacement utilized almost entirely trenchless construction, minimizing impacts to valuable environmentally sensitive and irreplaceable natural resources; the main distribution lines were replaced using high-density polyethylene (HDPE) pipeline by the pipe bursting method. The polyethylene pipelines were pre-chlorinated to disinfect and bacteriologically clear the line above ground prior to installation. This allowed the new lines to be placed into service immediately with minimal disruption to the visitors and residents at the Park. This project is the largest application to date in total linear footage of this technology in North America. This paper documents the installation of the new pipelines, focusing on the use of pipe bursting and pre-chlorination techniques.
