WSIP最大的努力改善了Calaveras大坝的地震安全性,并增加了储水以减轻干旱。

十年前,旧金山的公用事业委员会制定了一个大胆的计划,为下一场地震或其他自然灾害做准备。由此产生的48亿美元的水系统改进计划(WSIP)包括整个湾区的83个单独的项目,以提高地震和交付可靠性,确保水质和增强供应。新利18备用网址

"Being part of a program that has a clear purpose and such a tremendous benefit to the public has been inspiring," Wade says.

With the program 85% complete, tough remaining projects mean WSIP faces "some of its most demanding challenges," says Emilio Cruz, SFPUC assistant general manager. "We are confident that Dan's strong leadership and water infrastructure expertise will enable us to complete this program successfully."

该市在内部管理所有WSIP项目,并将设计顾问和承包商新利18备用网址整合在一起,以与市政府工作人员合作,甚至向所有人发行了带有相同团队徽标的硬汉。这样一来,“每个人都是同一个团队的一部分,朝着同一目标迈进。”

The collaboration has resulted in innovations in design, constructibility and project management. At the Hayward Fault Seismic Upgrade, for example, designers combined multiple strategies adapted from other industries to protect an essential water pipeline during an earthquake. Housed within an underground articulated concrete "vault" box, which can flex up to 6.5 ft like an accordion, the pipeline also can rotate via two massive, 72-in. ball joints—the largest ever manufactured. A 77-ton slip joint equipped with pressure- balancing cylinders allows up to 9 ft of compression.

在其他地方,工作人员准备在旧金山湾下方七个月之前完成一条五英里长的隧道。该设计避免了沉浸管道会产生的环境影响。韦德说,与其他大加利福尼亚州公共项目不同,在整个计划中,没有任何诉讼才新利18备用网址能获得环境批准。
