San Diego 净水管线收官：8 英里钢管全线贯通，每日 3,000 万加仑净化水将送往 Miramar 水库
位于加州圣迭戈县的 San Diego 市 11 月 4 日宣布，Pure Water 净水计划北城管线（North City Pure Water Pipeline）最后一节管道已在 Scripps Ranch 社区的 Hoyt Park Drive 地下安装完成，全长 8 英里多的地下管线全线贯通。系统启用后，这条管线每天可把 3,000 万加仑净化水从 Sorrento Valley 的北城净水厂（North City Pure Water Facility）送往 Miramar 水库。
该项目总投资 1.82 亿美元，2021 年开工，内容包括 8 英里直径 48 英寸钢管与光纤设施、6 条隧道和 1 处铁路桥跨越，还在 Miramar 水库附近新建一座除氯设施，并在水库内铺设约 1 英里水下管线分配净化水。它是 Pure Water 一期 12 个重大建设项目之一，一期也是 San Diego 市历史上规模最大的基础设施工程。最后一节管道落位后，施工方将开展系统调试与测试，未来数月还会完成路缘坡道、路面重铺与标线恢复等收尾工程。
市长 Todd Gloria 表示，他上任时 Pure Water 是 San Diego 历史上规模最大、分量最重的基建承诺，如今纸面上的承诺变成了地下 8 英里钢管，项目每天在本地生产 3,000 万加仑水，减少对进口水的依赖。市公用事业局局长 Drew Kleis 说，这条管线是把净化水送往 Miramar 水库的关键一环，并感谢沿线居民与商家在施工期间的耐心。整个 Pure Water 计划 2035 年全面建成后，将满足 San Diego 近一半的本地供水需求。（来源：圣迭戈市政府）
San Diego Completes Pure Water Pipeline: Eight Miles of Steel in the Ground, 30 Million Gallons a Day Bound for Miramar Reservoir
The City of San Diego, in San Diego County, California, announced on November 4 that the final piece of pipe for the North City Pure Water Pipeline has been installed underground on Hoyt Park Drive in Scripps Ranch, completing more than eight miles of underground pipeline. Once active, the line will carry 30 million gallons of purified water per day from the North City Pure Water Facility in Sorrento Valley to Miramar Reservoir.
The $182 million project, begun in 2021, includes eight miles of 48-inch steel pipeline and fiber-optic infrastructure, six tunnels and one railroad bridge crossing, plus a new de-chlorination facility near Miramar Reservoir and about one mile of underwater pipeline inside the reservoir to distribute the purified water. It is one of 12 major construction projects in Pure Water Phase 1, the largest infrastructure undertaking in the city's history. With the final segment in place, crews will commission and test the system, and in the coming months will finish curb ramps, repaving and restriping along the route.
Mayor Todd Gloria said Pure Water was the largest and most consequential infrastructure commitment in San Diego's history when he took office, and that a promise on paper is now eight miles of steel in the ground, producing 30 million gallons locally every day and reducing dependence on imported supplies. Public Utilities Director Drew Kleis called the pipeline the critical link to Miramar Reservoir and thanked residents and businesses along the route for their patience. When fully built out in 2035, Pure Water is expected to supply nearly half of San Diego's local water. (Source: City of San Diego)
