从1901年到1960年，西雅图市建造了11座大型露天饮用水配送中心 水库。这些水库的规模从750万加仑到6800万加仑不等。1995年，西雅图 公用事业公司（SPU）向华盛顿州财政部提交了一份覆盖计划 卫生部（WDOH）批准。其中两个储液罐已更换为新储液罐 混凝土蓄水池和第三个用浮动膜覆盖的蓄水池。剩下的8个 在接下来的16年里，水库将被覆盖——主要是浮盖。在 同时，SPU管理着一个全面的开放式水库保护计划 WDOH批准。操作和维护人员解决了一系列问题 操作、侵入、动物和水库水质问题。制定了特别计划 在1990年的友好运动会，1993年的亚太经济会议， 以及1999年世界贸易组织会议。 本文介绍了SPU的开放式油藏保护计划，包括 安全、控制鸟类和空气污染物、水库清洁、水库出口 消毒、排除地表水和应急响应。保护 该项目在过去5年中经历了重大变化，包括向 以团队为基础的管理方法和来自社区团体不断增加的压力 以及这些网站的其他用途（如公园和电信）的倡导者 输电塔）。描述了项目变更，以及关键水质和 提供了相关的性能度量。特殊事件期间的特别规定 （亲善运动会、亚太经合组织和世贸组织）也有介绍。 包括数字。

From 1901 until 1960, the City of Seattle built 11 large open distribution drinking water reservoirs. These reservoirs range in size from 7.5 to 68 million gallons. In 1995, Seattle Public Utilities (SPU) submitted a covering plan to the Washington State Department of Health (WDOH) that was approved. Two of the reservoirs have been replaced with new concrete reservoirs and a third covered with a floating membrane cover. The remaining 8 reservoirs will be covered - primarily with floating covers - over the next 16 years. In the meantime, SPU administers a comprehensive open reservoir protection program approved by WDOH. Operation and maintenance staff have addressed a range of operational, trespass, animal and in-reservoir water quality issues. Special plans were put in place during the 1990 Goodwill Games, the 1993 Asia-Pacific Economic Conference, and the 1999 World Trade Organization meetings. This paper presents SPU's open reservoir protection program, which includes security, controlling birds and airborne contaminants, reservoir cleaning, reservoir outlet disinfection, exclusion of surface water and emergency response. The protection program has undergone a major change over the last 5 years, including transition to a team-based management approach and increasing pressure from neighborhood groups and advocates of other uses of these sites (such as parks and telecommunications transmission towers). Program changes are described and key water quality and related performance measures are provided. Special provisions during unusual events (Goodwill Games, APEC, and WTO) are also described.
